GPS Navigation Tutorial

[skatj]

Would anyone be interested in this if I wrote one? GPS is a pretty big thing so I'm a little surprised Admin hasn't already made one

I would be totally interested!...in fact i'm looking for a GPS receiver myself for my Pocket PC which eventually will controll my robot.

please do..i would forward to it.

no need to ask man, DO IT

[airman00]

do it!

Everybody interested, go buy a EM-406A right now, without configuration, it spits out GPS data in ASCII out it's serial port at 4800 baud. After than, simply configure it so automatic is off and ask it for data yourself with simple string commands.

Just read the datasheet and the NMEA manual, everything is covered.

I'm planning to get a gps receiver module with the same exact chipset. a bluetooth enabled unit that i wish to connect with my PPC.
anyone have any suggestions?

i just got my GPS receiver on ebay. it's a bluetooth US GloSat with SirF3 chipset.i'm messing around with the GPS and my pocket PC which eventually will be the brain of my Beast Bot

parallax has a GPS for about $90 that can be configured to send out ether plane text strings or it has "smart mode"
were you send it a request for some data (time data, heading, longitude ...) and if the data is available it sends it back I just got one and it works great I am planing on using it for a robot that follows way points.

Everything from parallax is a rip-off... just learn NMEA and get a $60 receiver from sparkfun which tracks 20 satellites and lets you configure it the way you want to configure it.

whats NMEA?

I cant find anything called NMEA related to electronics on google

PLZZZZ write a tutorial!!!

[skatj]

hey guys, I've been really busy and will probably still be until AP exams are over, so sorry!! I will get around to this ASAP

airman: NMEA is a standard format in which GPS strings are output. This way when you parse string outputs from a receiver you know exactly which character(s) will give you exactly what information you need (altitude, heading, lat/long, etc).

I haven't actually used NMEA before, since the parallax gps receiver has a "smart mode"where you simply request specific information with predefined functions, so my tutorial will focus more on the navigational math part when I finally make it.

edit: don't have time to find a really good website, but try googling "NMEA strings", "NMEA string parsing", or something like that, you might get more results

Havent u written a tutorial yet???

[Webbot]

Why resurrect a thread that is about 4 years old !!!

Just use WebbotLib it has GPS/NMEA support built in. If you have questions then start a new thread.
