Turn on the receiver. After 30 to 90-seconds, you
will see the Yellow “Files” LED flash once every

observables. Check that 5 or more satellites are
tracked (the blue LED will blink 5 or more times.)

Wait an appropriate time period for data
collection:
OPUS-RS

Maximum of 2-hours
OPUS-STATIC
Minimum of 2-hours
Maximum 48-hours
4-hours suggested minimum
Remember that the data is going to be decimated
to 15-second intervals. It is best to wait at least 1-
minute longer than required to insure that the
decimation process does not leave your file too
short.
