58 MiLLennium GPSCard SW Version 4.503/4.52 Command Descriptions Manual Rev 2
In support of the first two file types, NovAtel has created six ASCII log types that contain data records in RINEX
format (XOBS, XOHD, XNAV, XNHD, XKIN, and XSTA). A seventh pseudo-log type (RINEX) can be used
instead to simplify data collection. These logs produce multiple lines of output; each line ends with a NovAtel
checksum. Once collected these logs should be processed into the 2 standard RINEX files using NovAtel’s Convert
utility.
A sample session, illustrating the use of the commands and logs, would be as follows:
COM1> log com2 rinex ontime 30
(some time later - move to a new site)
COM1> log com2 xkin
COM1> rinex markernum 980.1.35
COM1> rinex antdh 3.1
(at new site)
COM1> log com2 xsta
(some time later - logging complete)
COM1> unlogall
It should be noted that the first line of this example is equivalent to these two lines:
COM1> log com2 xobs ontime 30
COM1> log com2 xnav onchanged
The use of the pseudo-log RINEX is for convenience only.
After the UNLOGALL command, the XNHD and XOHD logs are automatically generated if XNAV and XOBS,
respectively, were active.
4.4.1 Commands
RINEX
This command is used to configure the user-defined fields in the file headers.
The settings of all these fields are visible in the RCCA log. All settings can be saved to non-volatile memory on a
MiLLennium card by the SAVECONFIG command. A CRESET command will empty all text fields and reduce
to zero the antenna offsets.
