Hello, I have a basic question about understanding the .pos files created from my base station’s static observation data. There are several columns in the table, and I can’t find anywhere that explains what each of them means. Some I understand, but others I don’t:
GPST: GPS time (equivalent to UTC?)
latitude(deg): latitude
longitude(deg): longitude
height(m): height (orthometric or ellipsoidal?)
Q: ?
ns: number of satellites (?)
sdn(m): ?
sde(m): ?
sdu(m): ?
sdne(m): ?
sdeu(m): ?
sdun(m): ?
age(s): age of the fix in seconds (?)
ratio: ?
Thanks in advance for the help.
