    I did a search and have read bits and pieces from different threads about similar issues. Flying last night for 20 min on clear open beach only 20 feet away from me with 7 satellites at 100 ft up (Flying in vision mode-GPS assist) My green flashing GPS lights switched to flashing yellow. Then went back to green then right back to flashing yellow. I noticed i didnt have a safe hover anymore so I brought it right back down.. THIS HAS NEVER HAPPENED With P2v or this bird before last night.
    I check the intermet for GPS issues and nothign reported. Is this another unknown?

    Was scared sh#tless...

    You did exactly the right thing in bringing it home if you weren't comfortable, although no need to panic. If the aircraft sees fewer than 5 satellites then it enters attitude hold mode (yellow flashing indicates) which means it will still hold height, hold orientation and keep itself upright and level - the only thing it can't do is keep its position over the ground as it will now drift with the wind, hence your hover situation. As to why it happened - sometimes it just does. I flew this weekend and one day 1 at take-off I was getting 8 and 9 sats, day two in the exact same location I was getting only 6. I tried moving it about 4 feet and I could get 8 again. I chalked it up to one of those things and had some great flights. :)

    I suppose there's no possibility that you accidentally toggled the S1 switch. Also could be a transient transmuter signal lost. Could your controller batteries possibly be dying?

    I apologize for cross posting, but wanted to see if anyone's got an idea about this:

    I was wondering about 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?

    I've been reading this forum for about 5 minutes this morning and this is the third time I have read this post in three different threads. Why apologize if you're just going to do the same irritating thing time after time?
