GPS Update fequency and Dead Reckoning
Righto guys, Scouse Monkey is now venturing into GPS for his PC and decided USB GPS was crap and OEM GPS was the way to go but i didnt like the look of the Garmin 15-L - it seemed to be the best but was lacking.
I am now looking at some modules that update faster than the normal 1Hz and also possible dead reckoning addons.
what i need to know is:
1st - can any of the guys working on the SDKs and various GPS software tell me if any of the programs can take an update speed of more than 1Hz and if there is any control features to the recievers to change the GPS update speed. Or does the software take an update when and if it recieves it.
2nd - can people please post some links to GPS modules etc - especially if they have or are to do with dead reckoning. We have a few links but anymore would help.
So far we have nice simple systems that just need a GPS antenna, a link to the speedo pulse and a small Gryo (actually quite cheap). there are a few other optional things and some that have compasses and tilt sensors but that is OTT for now.
The deadreckoning is all done int he reciever so the PC and software doesnt even know its going on. (unless you want it too - just to prove it works).
Finally, this looks like a pretty neat tool: http://www.tycoelectronics.com/gps/software.asp
