And yes to be sure I sped time up to make sure I had at least six sats visible to me (it went up to nine visible at times) throughout many days. It didn't drop below six. Now suddenly it won't read any sats visible. Edit: Also had the receiver (Of course all 16 GPS sats had the transmitter), added a second receiver to see if that was an issue (it wasn't), redid the receivers, used a different ship with a receiver, and so on. So far no luck getting it to read anything other than zero sats visible. I'm actually proud of myself for putting that many satellites up around Kerbin. They're all separated by 90 degrees on 4 different orbital planes (0, 45, 90, and 135). Was one of the more difficult missions I've done in KSP so far! So I really wish it would work! Edit Edit: I reloaded the game and it started working again. Then I went back to the VAB and relaunched. Again, not working. I think it *might* have something to do with relaunching, or reverting the flight back to VAB (and/or back to launch, not sure on that)
