I believe there is a swarm function that hidden in MP, but I have no idea what it is, how it works, or even how well it works.
I have a lot of info for you, and I'm based in the UK, I've sent you a message!
Interesting, thanks Euan. I don't suppose you have any links/leads for further investigation?
Thanks Dave. I'm messaged you back.
He's a brief explanation Euan
Thanks, thats really helpful.
Probably a courtyard is a very difficult environment for a GPS to work properly. The signals bounce off walls and arrive at the receiver twice, and/or with a delay that confuses it.
If this is right (test fly the copter in an open space, see if that makes a difference), one possible improvement could be to improve the polarization of the antenna. That will help reject multipath signals. See http://avrproject.ru/EB-500/GPS_Antennas_ApplicationNote-GPS-X-0801... , about "axial ratio" for a patch antenna, or replacing it with a helical antenna.
When did you get you Piski units? I'm still waiting!
Sorry Shaun just seen you're post. Hopefully you've got your's already. We got them about a month ago but had told them that we where up against it time wise so they may have sent ours out in one of the first batches. I know that theory are working flat out to get everything out so if you don't have you're yet I'm sure you'll get them soon.
Yes thats a bit of a worry. Even with the RTK system we'll need a lock on at least 7 satellites.We've going to start doing some testing a.s.a.p to try and workout what the reception will be like and what if anything we can to to iron out any issues.
