I have the below problem with the RINEX Header… Can anyone shed any light on the below?
I had to change the file extensions to get them into Leica Infinity (.obs->.19o abd .nav ->.19n). This did the trick and the data came in nicely.
Problem is that there are a couple of key pieces of information missing from the RINEX file header:
No IGS Receiver type, which is needed for the post-processing software to compensate for GLONASS inter-frequency biases.
No IGS Antenna name, which is needed for the pos-processing software to compensate for the phase center offsets.

One clue is that the RINEX file say’s it’s been converted from u-blox format, which indicates that it’s a u-blox receiver inside.
I’ve had a search through the IGS receiver and antenna lists and can’t find any u-blox stuff:
I’ve even tried hacking the RINEX header with ‘u-blox’ but Infinity doesn’t recognize it.
It might be worth checking with the manufacturer if they have the receiver and antenna types registered with the iGS or at least have antenna calibration files available (absolute or relative in ANTEX format).
