Collecting Static Data
You can collect static data with either the Base or the Rover. A typical use for static data collection would be
subsequent processing in OPUS, RTX, AUSPOS or manual post processing using a tool like CGO.
Prior to using the receiver, charge the batteries or use an external power source to insure that the static occupation is
not interrupted by power failure.
The internal battery when new and fully charged will run the receiver for around 5-hours, for occupations longer than
4-hours you should provide external power to the receiver with the included battery clips.
Place a freshly charged battery into the receiver.
Place the receiver above the point you want to survey.
Rotate the receiver so the pushbutton panel faces the North.
Level the receiver.
Record the ‘Vertical Height’ from the top of the survey mark to the bottom of the receiver; alternatively you
may measure a ‘Slant Height’ to the blue rubber gasket.
At a minimum, make a careful note of the following items in your field book:
Start Time and Date
Instrument Height (HI)
PID (Point ID, Mark Name)

Turn on the receiver.
Check that 5 or more satellites are tracked (the blue LED will blink 5 or more times.)
If the receiver is not configured to automatically begin data collection, push and hold the ‘Files’ button for 1-second
to begin data collection. You will see the Yellow “Files” LED flash once every epoch (default 1-second) as the receiver
records observables.
Wait an appropriate time period for data collection:
OPUS-RS (Rapid Static)
Minimum of 15-minutes
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.
At the end of the occupation Press and hold the ‘Files’ button for one-second.
Make a note of the end time in your field book:
