 Bigger Bigger  Smaller Smaller  Reset Reset

Hey all,

I'm working on an Arduino-based quadcopter project and want to add routing abilities to my project. I already have a slew of sensors up and working, so that leaves GPS.

Can someone recommend a relatively inexpensive, entry-level GPS unit? I'd prefer a shield, but any sort of rig works. I've been through SparkFun's collection, but was having a bit of trouble deciphering all the information.

I understand that the territory comes with a bit of a price tag, but I'm hoping to find something that works that doesn't completely eat my wallet.

Thanks in advance!

You just need a bigger wallet.

That may be true... Have you had a particularly favorable experience with a particular device?

No. All I can tell you about GPSs is 1) don't get them wet and 2) don't drop them at 60mph. Neither thing is really good for them.

I have a whole pile of non-functioning GPSs from being dropped, gotten wet, gotten smashed, etc.

I used the UP501 for a dozen projects, as it was so cheap here in South Africa,  ( $14 )  but when I tried to order again last month, they said that was an old batch and the new ones are now $38 !

They are easy to use though.

From PaulS experiences, perhaps you can make an umbrella/parachute for the gps module :-)

From my experience running a team of engineers that developed, productionized, fielded, and supported a UAV system in a combat zone I have found GPS modules to be amazingly robust when it comes to mechanical shock.  I have seem small UAVs landed into a concrete wall at full throttle and fly the same electronics in the same or another bird by a simple swap out.  Note: UAV engineers often use the term land where a customer might make the mistake of saying crash.
