A couple of questions about the current DPOS reports.
1) First my reports are now adding a 'B' to the lat/long information (see attached pdf). I am guessing that this is some kind of error, or does it have any meaning? This is new this season, I have not seen it before.
2) I suspect that this is some assumed knowledge that I am missing, if so I greatly appreciate anyone who can fill me in. I am unclear on how to know what ellipsoid is being used in reporting height. The report does not specify. How do I find that information? Since GRS80 is the recommended ellipsoid for ITRF2014 I am guessing this is what is being reported? However what ellipsoid is reported for NAD88 (the same?)? How would I know this if it is not documented on the DPOS report and since DPOS has no other documentation? Are there other documented sources it is drawing from?
I have come across mention of a CORS coordinate catalog here in the forums that DPOS potentially follows. I find the below webpage which describes the coordinate systems used by CORS but does not describe ellipsoids or geoid selections. Is there another location/document I am missing that would be relevant to this question?
3) If any DPOS documentation/manual exists I would greatly appreciate knowing about it.
Thanks!
