Thread: GPS satellite reception issues

Couple of places in NZ are a little weird as well - one area was showing me 250m underground and another had me 150m above ground. A little weird when you are trying to work out tracks and things. The new topo map reference model or datum they are using appears to be a lot better in that respect. Going to Mr Purple's maps also helped, but they do appear different to the Topo50's. On that note, is there a more recent release of the Mr Purples maps?

Must have a chat to my son - he works for Dawn Aerospace. Maybe the thrusters they make for European satellites have push some out of obit??
