Chapter 4 Using the Radian IS
The following is the factory setup for the POWERUP
configuration and an explanation of the meaning of each log:
range ontime 10.0 .............. GPS data logged every 10 seconds
rawephem onchanged ...... ephemeris data logged every time it
changes
almanac onchanged .......... almanac data logged every time it
changes
rtcaobs ontime 1.0 ............. base station GPS data transmitted
every second
rtcaref ontime 10.0 ............. base station position transmitted
every 10 seconds
avepos 0.025 ........................ the receiver will average its position
for 0.025 hours (1.5 minutes) and
then fix to this position
The first three logs (range, rawephem and almanac) are
typically used for post processing and are logged to the data
card. The last three (rtcaobs, rtcaref and avepos) are typically
used for an RTK base station, and rtcaobs and rtcaref are
transmitted to the radio out of COM port 2.
Though some of the logs in the POWERUP group are useful for
post-processing and others are useful for a base RTK system, all
logs work to your advantage because the Radian IS will
perform as a static/kinematic receiver if a radio/modem is not
present, or as an RTK base if the radio/modem is present. By
including all necessary logs for either configuration into the one
POWERUP group, you will not have to change the default logs
if your Radian IS is switched between static and RTK base.
4.5.3 Data File Naming
Although file name conventions are explained in this section,
you must refer to your Planning Reference Manual for
instructions on setting up a schedule.
