there is a lot of information out there about GPS, its potential precision, its limitations, its applications...here's a website that can allay the fears of some, reinforce the suspicions of others, and give insight to those who are interested.

Here is a good power point document about the datum stuff (or what made me think I was always 200m off when I debriefed with the GPS recorded route!!).

If anyone gets stuck teaching/learning PLGR. There's a program out there, that replicates the GPS itself. Which saves you from reading the ever so simply designed manual, and spending hours punching in random buttons.

As a result I could fire it up, change it from FIX to CONT. Plug in all the datum. Do direct nav, or setup a route, and adjust my alerts accordingly. And the "mark, mark" process. Jeez, I wish I knew about that years ago. Typing in the Grid Zone designator, and 100 000m identifier over and over was an annoyance to say the least.

...Now, if i can just remember it all....

On another note. Anyone trial the DAGR yet? Is it as userfriendly as the PLGR? :rolleyes:

Ender, perhaps you'd want to share the name of this program, or where it can be found?

Not sure the name of the program. I'd be tempted to guess it's made by Rockwell Collins though. "Inversion Trainer", rings a bell, but probably isn't right. I'll do some digging.

Edited to say: I googled and got the Rockwell site. I'm pretty sure this is the program we used. It doesnt' ring a bell, but the right answer never does.

Any 5th Group members who want a class to fill an afternoon give me a PM. I've taught GPS as a guest speaker at Austin Peay State University (that's Clarksville, for the non-Ft. Campbell guys), was trained by Trimble, and critiqued the FAA web site resulting in a change to their description of the GPS system.*

*And exactly what is the difference between triangulation and trilateration, anyway?
