(these versions as of Feb 2003)Brooke's Comment - Although this is a P code capable receiver, since SA was turned off May, 2, 2000 it's questionable how the position accuracy compares to a civilian 12 channel receiver like the Garmin hand held units. For military operations the Anti Spoof (AS) part of using a key may have an advantage against a sophisticated enemy, it's of little use against a not so sophisticated enemy. Hopefully the GRAM will be a 12 channel receiver.Follow-up comment: This 5 channel GPS receiver is the most sensitive I've worked with. It will lock up on signals that are right on the horizon whereas the Garmin 12 channel III Plus and the Motorola 8 channel VP Oncore receivers need the sat to be maybe 10 to 15 degrees above the horizon.

GPS has two classical applications: position and time and the PLGR is used for both of these.Position
Provides position information using both L1 and L2 with SPS and PPS capability thus will provide position in combat conditions.Note: The PPS Anti Spoof capability is effective against spoofing, but in my opinion it's more likely the enemy would use a jammer rather than a spoofing transmission. A jammer will just cause the GPS receiver to not lock hence it will not update the position.Once the satellite almanac has been loaded and you are in Figure Of Merit (FOM) mode 1 (the best condition) then in SETUP you can change from CONTionious mode to STandBY mode then into AVeraGe mode. (You can not go directly from CONT to AVG mode, but must first go into STBY mode. Then in the POSition menus you will find a screen that shows the averaged position. At my location it shows:Note 2: The PLGR seems to choose satellites that are dispersed horizontally, rejecting a satellite that is overhead. This may be part of the SETUP and depends on what you are trying to learn. This PLGR mode would be good for Lat & Lon but poor if Elevation was important.
* The averaging function stops at 32400.

Note1 - There appear to be two different elevations (either around 280 or 250 meters), this is probably my error or a difference in the elevation reference.
Time
Modern frequency hopping radios like the SINCGARS VHF low band radio and the "Have Quick" UHF military aircraft radios both depend on very accurate time as part of the frequency hopping scheme. The PLGR supports both of these radio systems in terms of precise time synchronization. It has a 10 micro second resolution.
There are two ways to use the Have Quick time code. With a direct wire connection or over the aircraft radio. When over the radio the code needs to be send as audio tones rahter than as DC voltage levels.
Have Quick II has a bit period of 600 us and an HCMOS output level.
The Have Quick time code specifications are:
SS-110990
ICD-GPS-060 - uses the MIL-STD-1553 aircraft bus to distribute time
STANAG 4430
SINCGARS TOD
The SINCGARS Time Fill cable is the Rockwell p/n 426-0141-070 (NSN 6150-01-375-8666)
It's a 6 contact U-229 on both ends type cable just over 3 meters long indicating that the radio can be left in a vehicle and the PLGR moved to somewhere outside (maybe even a man standing on the roof?).
The RT-1439 and RT-1523 will NOT accept time from any fill device, like a PLGR.
The RT-1523A and newer SINCGARS radios accept time fill.
Have Quick TOD
The NSN 6150-01-375-8665 CAGE: 13499, P/N: 426-0141-040 Cable is for loading the Time Of Day into a Have Quick RT-1319 225 - 400 MHz radio. This is for the frequency hopping, not the voice crypto. The radio connector is a Bendix-9137 JMS27467T15B35S 1467830 only sockets 10 and 11 are connected. The GPS receiver connector is a standard military AUDIO MC329G2 6 pin type.
One application of the RT-1319 is as a part of the GRC-206 system which uses the O-1814 Rubidium Frequency Standard to maintain Time Of Day for the Have Quick part of the UHF air band radio. Pin 11 related to the RT-1319 is ground.

Have Quick data protocols comes in a number of flavors. They all start with the basic Time Of Day data then there are additional data fields for Day Of Year, and another that adds Time Figure Of Merit after DOY. SINCGARS has a slightly different way of computing the calendar. So there are different time fill formats and or signal levels available on the PLGR J1 and J2 connectors.
Also see the O-1814/GRC-206 Rubidium Oscillator web page for more on Have Quick time code.
Target Finder (Gun Laying)

Gun Laying and Positioning System (GLPS): M67 (NSN 6675-01-430-1965) (EIC: 3XA)
31 October 2000
The M67 consists of:
Laser Rangefinder MRF2000-2 covering 30 to 2500 meters,
T502S Theodolite -
The combination of Theodolite and range finder is called a Total Station (Wiki) in the surveying business.
SKK3-08 Gyroscope (for North Finding)
PLGR GPS receiver and related poles and tripods.
The heart of this system is the North Finding Gyro. The PLGR is an accessory that allows finding Lon & Lat.
The Target Finder function in the PLGR is based on Way Point calculation using either Slant Range Calculations (SR-CALC) or Range Calculation (RNG-CALC).
Status
This is something I don't understand. When viewing the status of the received satellites (MENU -> Status) then up or down arrow to this page:
PLGR Status page with ID column showing 4 satellites
SV is the Space Vehicle number
CN is the Carrier / Noise ratio, ie. signal strength
CD is CoDe: CA, P or Y
ST is Status:
I = InterferencePhoto taken using built-in antenna indoors so SV#s 06, 09, 18 and 14 are in Search status.
R = Recovery
S = Search
T = Track
Left arrow showing all 5 channels being tracked.
But the left most channel always seems to be in P code mode. Is this a bug in the PLGR or . . . let me know.
Sometimes when the helmet (or any external) antenna is connected all the CoDe values are CA. But right after a new satellite shows up in channel one it's code shows as "P" for example SV 09 showed P but when SV06 showed up it was CA. Channel 1 seems to be used to search for satellites rather than track them and so defaults to P mode.
The tan case PLGR draws about 150 mA so you can estimate battery life. The green case PLGR draws about 75 ma, 1/2 the current of the tan case units. The OD green case PLGR is supposed to draw maybe 1/2 the current.Main
This is a plastic cased receiver and they have done the same thing that was done in the SDU-30 marker light. That is to require a special battery with both contacts on the same end. By doing this they don't need to use a metal cap and can keep the power circuitry shorter. But the problem is then placed on the battery vendor to bring both contacts to one end..6 Volt Lithium Sulfur dioxide BA-5800A/U NSN 6135-01-440-7774.
The old BA-5800/U NSN 6665-99-760-9742 is obsolete. Probably because the lack of a charging prevention diode allowed it to explode when using in equipment, like the PLGR, that has provision to charge the battery.If you use AA-alkaline or AA-lithium (? chemistry) batteries, you'll need eight of them, plus battery holder, NSN 6160-01-3854358.
BA-5800 Battery Adapter holds 8 each AA cells and can be used with either 4 or 8 cells to supply 6 Volts nominal..
BB-2800 (NSN: 6140-01-490-5372) is a Li-Ion rechargeable battery and can be charged using the PP-8498/U charger that comes in what looks like a small suitcase very similar to the PP-8444()/U. Supposed to be fielded in early 2003.
Ni-MH rechargeable (NSN: 6140-01-400-2902). The PLGR has a charging circuit for this battery and maintains it charged when external power is connected. GPS Pathfinder magazine Issue 10 No. 3 says that only this particular battery will be charged. But they don't say how that's accomplished. It may be that in July 2003 the BB-2800 was not yet fielded and so there was not any rechargeable BA-5800 size battery. Note that the BA5800 battery adapter contains combining diodes and will not allow charging current into the AA cells. This means it's safe to use as a backup while an external power supply is being used.
Ni-MH cells are not amenable to "trickle" charging. If a DC trickle charge is used the battery will overheat and it's life may be as short as a few months. The proper way to maintain a Ni-MH battery is to use a pulse method where the duty cycle is about 1/500.
If you know more about the charger in a PLGR please let me know.
Memory
This Hold Up Battery keeps the crypto key alive, almanac, ephemeris and error log. This AA size 3.6 Volt Lithium battery has conventional construction with positive on one end and negative on the other end. The battery compartment cap is metal. Positive in first, negative is cap/spring.
Because the error log is maintained by the memory battery you should leave the memory battery installed when returning a unit for repair.

Note
Although this battery is the size of a standard AA cell, a standard AA cell is 1.5 Volts and is way below what a 3.6 Volt cell is even when dead. Don't bother trying a 1.5 AA cell, it will not work.
SAFETY
Note there are 3 ways a PLGR can be connected to a military vehicle battery system.
(1) connect across both batteries for a 24 volt power source. This is OK
(2) connect across the 12 volt battery that tied to chassis ground. This is OK.
(2) DO NOT DO THIS! connect across the 12 volt battery that's not grounded. This will cause the Memory battery to explode! DO NOT DO THIS!
There is a permanently attached antenna that probably is a quad helix. In addition you can connect an external antenna to the connector on the back. Helmet Antenna AS-4334/U and Remote Antenna AS-4333N are made by Spectra Systems, Inc. FL.
The PLGR uses 5 Volt antennas. The newer DAGR uses 3.3 Volt antennas.
The PLGR is a L1 frequency only receiver, yet many of the antennas are dual frequency (L1, L2). Why is that? Let me know.
Indoor Operation Without the Special Antenna Connector
In order to use my roof mounted house GPS antenna and 4 way power divider to feed the PLGR GPS signals without the special RF PLGR cable, I just used the antenna from my Garmin GPS III Plus. It looks like a miniature PLGR antenna and even has a flat side just like the PLGR. By taping the Garmin antenna to the PLGR antenna the PLGR works very well. In fact the PLGR will lock onto signals that my Motorola VP Oncore receivers can not lock onto.The connector needed to make up an external antenna is a Combo-D series made by Positronics Industries, model CBD5W1F20 00X with the coax insert FS4202D

This antenna has 22 dB gain and takes 5 Volts on the center conductor at about 50 ma. So the PLGR could also power most 5 Volt external antennas using an adapter cable to get from the DB-9 shell coax to a standard coax connector.
Helmet Antenna Mount.

There is a pocket to hole the antenna with a Velcro closure. Note that the antenna should be installed in the pocket with the active face opposite to the closure so that the metal hooks on the end of the elastic bands will grab the helmet edges without a twist in the elastic band. The metal clip with square corners has a label "BACK". The other two metal clips with angled ends have no label.
The PLGR has a 15 pin "D" series connector that is the same type used on PC video connections. The digital interface is in RS-422 protocol thus providing greater distance and higher speed than can reliably obtained from RS-232. There is also a standard RS-232 interface for use with a PC. There are also timing inputs and outputs to support precision time transfer.
One use for this interface is to couple the PLGR with a military VHF low band radio like a SINCGARS or Bowman. This allows the position of the radio to be sent, automatically in some cases. It also allows traget coordinates or Close Air Support messages to be sent (requires bearing and distance between user and target typically from a Laser Range Finder).
The data protocol is defined in ICD-153. It's a binary protocol and an expanded version is used for the DAGR.

This is an octopus type cable with a DB type 15 socket and a 765K plug on one end to attach to the PLGR (no threaded connector for this application) and at the other end there is a standard 9 socket DB serial connector that connects directly to a computer, but in addition there is also a DIN type 5 socket connector that connects to a power supply to power the PLGR.
( Not sure about this: so that a battery is not needed on the PLGR, as would be the case when it's returned for reprogramming.)
It's more likely that the 12.0 +/- 0.5 Volt external power supply is required to programming the EPROM used in the PLGR (Wiki).
The DAGR can be reprogrammed with a simple DAGR/PLGR to DAGR/PLGR serial data cable, i.e. the DAGR does not need the programming voltage.

By tying the computer DB9 connector pins 1, 4, 6, 7(RTS) and 8(CTS) together the computer thinks is has hardware handshaking (Request To Send from the computer drives the Clear To Send input). A power supply with a DIN 5 pin plug supplies both power to the PLGR and the 12 Volts needed for the EEPROM programming. Looking into the end of the DIN connector with the alignment notch at 12:00 o'clock the pins are numbered starting at 3:00 o'clock and going clockwise: 1, 4, 2, 5, 3.
Since the programming voltage ground is completed through the EXT power jack on the PLGR, the external power plug must be installed, even of there is a main battery in the PLGR.
This cable should also work for use with the PC mission planning software.

Using a simple LabVIEW program and the above programming cable I can see data coming out of the PLGR.
I used the Collins MicroTracker Designer's Guide binary data format information, which seems to match this data. I expect that each manufacturer has their own GPS binary data protocol that's used on all their products. That's the case with Motorola and Trimble.
There is a simple message that is sent out about once every 5 seconds, it is in Collins binary format:

I got this on eBay advertised as a "Rockwell PLGR-II GPS Crypto Adapter Cable".
The unopened plastic bag has a label: 12499ASSY-988-3116-001 REV A (this line is also molded into the DB-15 connector plastic) MFR TSE-J 7-24-98
p/n 988-3116-001 is listed on the PLGR-II+ADK Rockwell web page as a "crypto adapter cable", but is not listed on the PLGR+96 web page.
The cable itself has a DB-15(f) connector on one end and a 329G2 6-pin AUDIO connector on the other end. The AUDIO connector mates with "J1" on top of the PLGR, or with a crypto fill device.
The most likely way this is used is to connect the AUDIO connector to the fill device and the DB connector to the PLGR.
Note that most computers have a DB-9(m) connection and so this cable will not fit. It will connect to the end of a computer monitor cable, i.e. this is the same connector that's on a computer for the video monitor.
The DB-15(m) connector DOES fit the J2 Data Connector** on the back of the PLGR.

Takes 9 to 32 Volts, positive on the center contact. BUT the negative lead must be ground, it can not be higher. If the "hot" battery in a dual battery system is used for the PLGR smoke will come out of the wiring. THe PLGR has an internal switching mode power supply so it's current draw varies with the input voltage. At 9 Volts in the current is about 200 ma and at 27 VDC in it's about 80 ma, in either case about 1.9 watts.NSN 6150-01-375-8661 p/n 426-0144-010The manual says the mating connector is a Switchcraft RA-765 which is part of a cord assembly. The 765K (Red handle) or 760K (Black handle) pug do fit properly. The "K" suffix means a threaded locking ring, the parts without the locking ring are 765 or 760.
The Radio Shack 5.5 x 2.5 mm 274-1573 DC Power Plug can be used for external power. But it does not have the screw down locking collar and so may very well fall out.
The Switchcraft 761K does NOT fit, it's too long. Switchcraft parts with an "S" prefix have a Small hole and will NOT fit the PLGR.
Collins DC Power cord with spade lugs one end and the special PLGR screw lock connector on the other end. Only one line fused. I don't know which lead is fused. If it's in the hot (+) lead there's a possible problem connecting the two leads to the "hot" 12 Volt battery in a 24 volt system then connecting something grounded to any ground point on the PLGR. This lets the smoke out of the PLGR!
WARNING There are no fuses inside the PLGR so when using external power you should supply a fuse, or better fuse both leads.
SAFETY Do Not connect the external power cable to the top (non grounded) battery in a military vehicle 24 volt system. Doing so will cause the memory battery to explode.
Hint When using external power it's good to also have a main battery installed, although not necessary. The reason is that if you have a power glitch in the external power the receiver shuts down and restarts. This is very time consuming and annoying but does not happen when you have a main battery to ride out the external power glitch.

- holds PLGR, remote antenna & cables, spare batteries.
A number of problems:
- The LCD can only be read with your eye below the bottom edge of the PLGR. You can not read the display when looking down from the top, like when it's mounted on a vehicle.
- The memory battery cap is very difficult to reinstall and, being a seperate part is easy to loose.
- The use of non standard batteries is bad enough, but using a "AA" size battery for the memory battery that's non standard must cause a lot of problems. Too bad since there is plenty of room in the box to use 3 each standard 1.5 V AA cells.
- Non standard connectors on the rear panel for: external power, digital I/O and antenna, these all could have been done using standard connectors.
- case is larger than it needs to be, making it awkward to carry.
- The displayed time is often wrong. Sometimes by one second and at others up to 41 seconds off. There is no indication that there is a time error.
Master Reset
If the PLGR fails to turn on, before returning for repair, try a master reset.
Remove both the main and hold up batteries.
Short the external power connector center pin to it's shell for a few seconds.
Install the correct 3.6 volt hold up battery and a main battery, both checked to be sure they are good.
Press the green ON button.On the very early versions of the PLGR it's possible that the time displayed is off (in my case by 41 seconds) and every other indication says the receiver is working properly. This is a large enough error that it would keep frequency hopping radios from working. By doing a master reset the displayed time because aligned with Zulu (UTC). This is a serious problem that probably was fixed in later firmware versions.

There are two ribbon cables going from the front panel to the rear printed circuit board. The white ribbon fits into a socket on both ends and the dark orange ribbon cable fits into a socket on the front panel PCB.The display was erratic and after a random time the display would change to some pattern or it would break up into gibberish. The receiver would not run for more than about 10 minutes without display problems.
By using a small philips screw driver to remove the 6 screws on the back and slightly separating the front panel from the back-box you can access the ribbon cables. They can be removed from the sockets by raising the socket clamp bar about 1/32". Then the ribbon cable can be slid from the socket. One side of the ribbon cable has metalized "fingers" that can be cleaned by using a fresh soft pencil eraser and then cleaning the rubber particles with something that will not leave any residue. DO NOT USE YOUR FINGERS TO CLEAN. Clean all 3 ribbon ends.
Pressing Up or Down causes the cursor to move Right
This caused by being in Number Lock mode. To get back into arrow mode press Num Lock so you see "P" in the lower right corner of the display.

This is a 12 channel using the NightHawk signal processor and Phoenix RF front end.
With the ADK (Azimuth Determination Kit) add on, angles can be determined to better than 3 mils and with a dual receiver system to better than 1/2 mil. A mil (1/64000 of a circle) is about 1 yard at 1,000 yards range.

GRAM - GPS Receiver Application Module
Standardized military GPS receiver used for embedding into systems. GRAM is actually a family of products, with varying physical configurations and functionality. Current planning calls for a minimum of three configurations VME bus and SEM-E for avionics applications, and PCMCIA for ground-based vehicle applications. This form is likely to be the most commonly-used for Army customers.

4. SUMMARY OF PROBLEM -
A. THE GLOBAL POSITIONING SYSTEM (GPS) JOINT PROGRAM OFFICE (JPO) HAS REPORTED THAT C-17, VH-60, AND HH-60 AIRCREWS HAVE REPORTED ERRORS WITH THE NAVIGATION SOLUTION IN THE RECEIVER 3A. THE FAILURE MANIFESTS ITSELF AS A GRADUAL NAVIGATION POSITION SOLUTION RUN-OFF (AS GREAT AS 20-40 NM) WITH NO WARNING TO THE OPERATOR. THE RECEIVER WILL CONTINUE TO INDICATE A FIGURE OF MERIT (FOM) OF 1 DURING THE RUN-OFF. THIS OCCURRED DURING THE FIRST MISSION AFTER CRYPTO KEYS WERE LOADED TO ACTIVATE THE RECEIVER'S SELECTIVE AVAILABILITY/ANTI SPOOF (SA/AS) FEATURES. ALTHOUGH THE REPORTED ANOMALIES HAVE OCCURRED WITH THE RECEIVER 3A, THE FAILURE MODE IS COMMON TO OTHER RECEIVERS INCLUDING THE 3S, UH, OH, C4, AND MANPACK RECEIVERS USED IN THE V1, V2, AND V3 CONFIGURATIONS OF AN/ASN-149 GPS SETS. THE PROBLEM IS CAUSED BY CORRUPTED DATA IN THE RECEIVER AND CAN OCCUR WHEN THE RECEIVER BECOMES AUTHORIZED TO OPERATE IN ENCRYPTED (P(Y)CODE) MODE. AUTHORIZATION OCCURS WHEN A PREVIOUSLY-LOADED GUV OR CVW KEY IS VERIFIED BY THE RECEIVER. GUV KEYED RECEIVERS RE-VERIFY THEIR KEY EACH ZULU DAY. CVW KEYED RECEIVERS ARE VERIFIED FOR THE DURATION OF THE CVW KEY.AVIACONVERSIA GPS Jammer

MOTOROLA, INC., Plaintiff-Appellant, v. The UNITED STATES, Defendant-Appellee. This is an interesting case where Motorola sued the U.S. claiming that they were not treated in a fair manner, since after burning a lot of Motorola's time and money during the specification stage the U.S. required a sample unit of a commercially available GPS receiver as part of it's bid package thereby eliminating Motorola from the bidding.
