Hello, all I have a couple of GPSDOs (KS, z3805a) hooked up to a fixed outdoor antenna through an HP 58516 splitter. I notice that when I powercycle the GPSDOs (which I generally try to avoid), the position they come up with differs from time to time in at least the last three digits (and height in particular varies with up to 30m).
I would like to get a better idea of what my actualt antenna location is, so that I can manually set the position in the GPSDOs. For that purpose I set up a Ublox M8N with logging in U-center, and I've collected about 250K readings over several days. For each reading I also log number of SV's used, as well as HDOP, VDOP. PDOP, thinking I would filter the list and end up with a subset of really good fixes.The idea is then to average the "best readings" and use that as my position. My question is twofold; 1) is this for some reason a bad idea? And 2) How do I average the numbers? I can not put my finger on it but it "feels wrong" to average lat, long and height independently. Any hints are greatly appreciated. Thank you!
