GPS Not Stable

[BlackTracer]

Am I the only one who notices a drop in satellites once the motors fire up??

Power up the PV2+ and wait. I get between 8 and 10 on a good evening. Fire up the motors and it drops to between 5 & 7.

I get no drop in number of sats after starting up and taking off. I always get more satellites after a time especially if I climb above 30 feet. If I take off with 7, which is typical where I have been flying, I get 11 and sometimes 13 soon after liftoff. Then they are maintained throughout the flight. BTW the thing is so stable with that many sats. When I fly around my neighborhood (i walk my phantom like some walk thier dog) which is heavily treed, sats range from 6 to 11 even when flying under heavy trees. I am very impressed with the gps system. It has worked well for me.

Ok. Thanks. I only have 5 flights so I'll just have to hope mine gets more dog-like.

Does anyone "in the know" have any idea whether it would be possible to replace the GPS receiver with a GLONASS compatible one?

I was wondering about the same. Maybe replace the GPS Antenna with one that has a higher gain?

I think this one below can be used to replace the P2V+ GPS antenna. However, am looking for something with more gain.

Like these, but not sure if these are too thick..

These are Glonass Antennas

This one is slighly thicker (by 2mm), but am thinking might work:

Anyone have experience with this?

could be a good idea to look inside for bad contacts ... interferences could be triggered by vibrations and disturb the gps

This sounds like a soulution if it works, so if anyone trie this out let us know!

Seconded. I'd pay good money to get a better satellite count more often and faster.
