Military Tech: GPS and Networking 185

    Many /.'ers are probably already familliar with APRS for position reporting over ham radio. APRS has some serious limitations, though, and there's an effort to develop a new, extensible, open protocol at opentrac.org [opentrac.org]. Things are just starting to take off, with prototype hardware in use and a couple of test programs written. Check it out and see what you can contribute.

              Slow? resource intensive?

              GPS uses triangulation, essentially, although it's a lot easier since it sends out a timestamp. To triangulate a unit, you would have to have 3 stations be time-synchronized and all would have to know they heard the same signal -- which is undoubtedly coded making it EASIER to know it was the same.

              In other words, tank A sends out an encrypted digital message of "here is my location". If 3 stations hear the signal and timestamp it to the nanosecond, they can them compare the signal--without knowing what it actually broadcast--and tell it was the same broadcast. Using the time data and and the exact location of each station, it's a simple matter to plot the location of the transmission. The farther apart the 3 stations, the better the accuracy. More stations would lead to more accuracy, plus you'd couldn't shut it down by bombing a single tower as long as 3 remained.

              This would essentially be a reverse-gps. It's only resource-intensive and slow if you have a single unit driving around with a directional antenna, like the FCC did to locate pirate stations. If you can synchronize the clocks and timestamp signals accurately, it's almost trivial to pinpoint the location.

          Civilian models are designed to be lightweight, waterproof, and reasonably accurate. Some will average selective availability to get a statistically more accurate reading. A 12-channel chip is the size of a dime. The newer ones with integrated map data are excellent.

          Military models have decryption software (basically a 3DES chip, I believe) which can listen to the encrypted channels broadcast by the birds but from what I understand, the MAIN DIFFERENCE is that military models have a more accurate clock than the civilian models. Because of this, even with SA disabled, they get triple the accuracy with 7 fewer channels.

The old units can only track five satellites at once, and signals from four satellites are required to establish a three-dimensional position. In addition, current G.P.S. receivers are somewhat vulnerable to enemy equipment that beams false G.P.S. signals to indicate the wrong location, a technique known as spoofing.

The important part here is that the PLGR's most common use (determining position for individual soldiers and vehicles) doesn't need a 3D position. Your position (including elevation) can be plotted on any map using only two coordinates. 3D positions are only important for aircraft, air defense, and artillery.

In other words, this is not some plastic Taiwanese el-cheapo GPS receiver you paid $300 for at wiggliesneatshit.com. Do you have any clue how much time and money it takes to build one-off mil-spec equipment in low volumes that the military routinely requires?

    I've actually found detailed technical information about the unit you're talking about. It's here [fas.org] and it's a damned interesting read. For instance, does your spiffy little 12 channel unit happen to have any anti-jamming/spoofing features? Exactly how many artillery shell concussion shock waves will your unit survive while your crew is firing the ol' 155mm? The DoD is so happy with the things they are trying to extend the warranty!

    The fact that some units have more modern equipment than others is a perfectly normal, healthy way to run a military. Some of you paying attention to our recent deployment to Iraq have learned that the Army's 4th Infantry Division has only just now arrived in theater. This happens to be the Army's "showcase" Division. If it's the latest, the 4th ID has got it. It's not that our government didn't want to deploy the 4th, but Turkey didn't cooperate and the whole outfit had to be floated around the Mediterranean. Basically, the most advanced ground force on Earth arrived just in time to become traffic cops. Meanwhile, the old fashioned 10-year-old PLGR units are probably exactly what the 3rd ID used to actually get the job done.

    You show me someone astonished by military procurement practices and I'll show you an ignorant fool. The next time you have the urge to compare your knowledge of equipment/technology to that of a military, just assume your wrong and shut up.
  • Here are two screenshots (reg req?) of FBCB2 [nytimes.com], a battlefield force-viewing program.

    Can someone tell me what OS it's running on?

    Plainly FBCB2 is using X11 windows to draw the display. But the open "Start" menu in the lower-left strongly resembles Microsoft Windows(tm), except for the replacement of the "Flying Window" logo with a yellowish blob.

    It seems excessively fragile to be running two boxes for the software and it's display- could it be that FBCB2 is a Unix program, but the Army has adapted a Micros
    • the WM looks like FVWM95??
    • Can someone tell me what OS it's running on?

      Looks like it runs on many different systems. Given that it is platform agnostic, the GUI likely is a motif app and what you see is a X server running on winblows. Look here [fas.org].

      • Given that it is platform agnostic

        Where do you get that?

        The slide says "integrated into the various platforms at brigade and below". But in that context (and in general when discussing military planning), a "platform" is anything which can have a gun put on it (tanks, APCs, helicopters, ships, etc. Even people)

        Is there any other source suggesting it's cross-platform in a software sense?

      (Yes Virginia, the dumb terminal is alive and well.)

      Said configuration is so common it's almost obscene. My first Job out of college was at one of Lockheed Martin's many branches.

      • So I've little doubt that it's pretty common in the actual military as well.

        I doubt it strongly. If you worked for a defense contractor long, you know there is a HUGE difference between the equipment used in stateside research labs and what is deployable in the field.

        Software thats going to be run in actual military combat should always be compact, embedded systems code. We all know the story of the battleship running Windows NT, which only demonstrates why this is a bad idea- and the military is usual

          Point taken, and correct. I guess I should clairfy that by "the field", I didn't mean combat. The project I worked on was development of automated test and diagnostic equipment that was mostly the business of the REMFs. Our stuff didn't go into combat. If the fancy toy

      He was running WinNT and even had an instance of Winamp running.

      Don't be foolish enough to believe the DoD would actually use Microsoft products for any of it's software needs.

      Interestingly enough, the Army's most powerful tanks, the M1A2, don't run FBCB2, they run the older and incompatible system which I believe is called IFIS. The 3rd Division in Iraq had M1A2s with IFIS and the recently deployed 4th is outfitted with FBCB2. The 4th is considered the Army's most "wired" division.

      • Hmm, I didn't spend much time at Stottler Henke's booth at IITSEC (although they passed out a great little invitation card, featuring an infantryman with an RS-232 port out the side of his neck).

        Slashdot readers might like to know that the primary platform for the OTB [onesaf.org] software referenced in that paper is Linux. (In fact, at one point the recommended distribution was Progeny Debian).
