GPS catastrophic failure
I was seeking a geocache (Czech Golf Courses #3: Klanovice, http://www.geocaching.com/seek/cache_details.aspx?guid=2adc1035-eb7c-4eaa-87b2-75a26c8e0d58) today, and pretty strange things happened with GPS: I got pretty close to cache, spent 5 minutes trying to get some signal. It got some: GPS was telling me I'm 9km above ground and 150km from my true position. Ouch. Cold start was needed, but did not help much. Now GPS was only wrong by about 300meters. [Did it have something to do with only 2D fix and billionton having no way to set my altitude?] I spent maybe an hour running in circles, then got to some meadow and got good 3D fix. Things worked okay from that point on.
