PLGR to Toughbook.

[Riftweaver]

Well, here comes a good one.....


I have a PLGR and I also have a Toughbook. Along with the PLGR, I have the communication cord that goes between it and a COM port on a computer. If I use Google Earth, how does it get the signal from the PLGR to pinpoint location?

I am unsure if my cable is good or not. I also don't know if there is any additional software needed.

You have to set the plgr data out to nema and then google earth to the correct com port and speed the plgr is set at.

I will try to work on this during the upcoming weekend. Thanks for the tips.

I can give better, detailed information on how to do it next week when I'm in front of the equipment.

It would be interesting to compare plugger performance to a modern GPS's performance. Interested? I have a toughbook coming this week that I can plug into my multiconstellation GNSS.

Only thing the plgr has over modern gps devices is the ability to receive additional military frequencies to help avoid jamming.

Other than that a gps is a gps.

Somewhat, but civilian GNSS tech hasn't stood still either (like military moving from PLGR to DAGR). The Ublox Neo-M8N chipset in my receiver can receive from: GPS/QZSS L1 C/A, GLONASS L10F, BeiDou B1 SBAS L1 C/A, Galileo E1B/C constellations (not just US based GPS), and it supports all of the SBAS types: WAAS, EGNOS, MSAS - and has an INDOOR receive sensitivity of -167db (and I put a Tallysman TW3710 dual band GNSS high-rejection SAW-filtered/LNA antenna). With more constellations available, more control points for each constellation available, and with various GPS signal encoding schemes used (and the GNSS receiver can receive from multiple and correlate simultaneously), the jamming is much harder.

It's not just the frequencies that help reject jamming - the signal type also helps. It's like the difference between analog cell phones vs. CDMA digital cell phones, where analog signals would fade and could be overridden by a noise source on the same frequency, while the CDMA type tolerate noise better and in digital form will reach further.

[EDIT:] To clarify, I'm most interested in differences with receive sensitivity and tracking stability (in-motion, and static). [/EDIT]

Ok I made a video just on doing this with google earth, microsoft map point and Ubuntu FoxtrotGPS.

Will post them in a separate thread, http://www.steelsoldiers.com/showth...k-and-use-a-RAMS-mount-to-create-a-moving-map
