GPS + mag combo wanted
« on: November 02, 2015, 04:58:44 pm »
Hello Im searching for a GPS/mag combo for Revolution board or sparky.
Are there any recommandations what to chose?
Can I use one thats meant for pixhawk?

I have bought at least 4 different GPS/mag units from eBay.

- Get a Ublox GPS/mag.
- Be aware that next LP release is planned to have external I2C mag support
- Be aware that next LP release may have Sparky2 FC support, and Sparky2 has more sensor ports available than Revo (and way more than Nano).
- Be aware that we are seeing problems with the Neo8 GPS's.  The GPS position can jump a fairly long way between two consecutive location packets.  If you want something right now vs. being safe and waiting for further testing on this (and can solder some plugs on), I would get a Neo7 from eBay like this one.  This looks like the Neo7 that I have that is my current top pick.
- If size matters, the Neo8 is smaller, and you can get even smaller GPS's than the Neo8, but my experience is the smaller, the lower performance (smaller antenna).
- There is some Ublox testing that shows that Neo8 with it's higher sat count does better in city "concrete canyons".
- are you going to stack it on an e.g. Revo or mount it on a pole?  There is a Neo6 that can be modified a little to make it stackable.
- are you OK with soldering different ends on the GPS cable?  If not, you can search around and find one for OpenPilot for maybe $10 more.

Here are some standard Flexi/Main connectors.  20 for $6 shipped.  That's enough to last a while.

Here is some tiny heat shrink tubing to help you make nice cables.  1M for $1 shipped.

For reference, the Neo8 being discussed

Thank you for that quick answer!
I have time to wait so should be nö problem waiting for next release to come and still have to chose a board...
Soldering and making cables an stuff ist part of my daily work, so no problem on this side.
Size doesnt matter that much and im going to mount it on a pole with 4-6inch high so that mag is far away from any cables or esc.
Thanks for the links that will really help me!
Answering from mobile device so im keeping it short...sorry for that!
I really have to thank the whole developer Team and all the experienced an wise guys here, its the first time contact with this software family for me thats why I have to ask much things hope Im learning quick...  ;-)
