Hello everyone i was wondering which gps module/ kit would be good for making a gps guided robot.? i want to make a robot capable of navigating from point a to point b by itself but there seems to be a lot of modules for sale. so far i have found: http://www.ebay.com.au/itm/1PC-Ublox-NEO6MV2-GPS-Module-Aircraft-Flight-Controller-For-Arduino-New/350849933793?_trksid=p3984.m2206&_trkparms=aid%3D222002%26algo%3DSIC.FIT%26ao%3D1%26asc%3D31%26meid%3D2230964419490146483%26pid%3D100052%26prg%3D1023%26rk%3D1%26rkt%3D9%26sd%3D350849933793%26
The best way to judge a module is to see which chipset it uses and look for chipset reviews. One of those units definitely claims to have a backup battery, which is definitely worth having (acquisition times faster from cold).
Sometimes you need an external antenna, that's an important factor.
Sometimes you want fast update, modules can be 1 update/sec, 5 update/sec, 10 update/sec, typically, so check that spec.
But basically they should all be interchangeable if them speak standard NMEA sentences (watch out for 3.3V v. 5V issue though).
Thanks for your reply. i will definitely look into that. :stuck_out_tongue_closed_eyes: Have you come across a tutorial about gps robots you highly recommend? Thank you
What sort of robot did you have in mind ?
The main problems with using GPS for experimental robots are (a) it doesn’t work well indoors and (b) the random errors in position calculations of roughly 2-3 metres create a lot of practical difficulting in using GPS for small-scale and low speed applications.
