OPERATION

INITIAL STARTUP

Both the internal GPS and WAAS receiver must perform a Cold Start the first time
you power up the system. The GPS receiver will search the sky for satellites and
download data necessary for operation. The WAAS receiver will wait until the
required almanac data is received. The cold start will take up to 15 minutes but is
only required during the initial power up.
Always make sure the antenna is connected to the receiver before powering the unit.
Connect the serial cable provided between the RPR 110 and your computer, apply
power and verify that the red power LED is on. Allow the receiver to operate while
you install the software program on your computer. Turn off all unnecessary
electrical equipment to minimize electrical noise interference.

NORMAL OPERATION

Upon completion of the initial "Cold Start", the receiver begins to operate in
"Normal Mode". The unit should be operating in full DGPS mode within a few minutes
of power on.
All configuration and WAAS data is stored in nonvolatile memory inside the RPR 110
110. Configuration changes are made with utility software.
Be aware of possible satellite obstructions, which may interfere with GPS operation.
For high precision applications, watch your Horizontal Dilution of Precision
(HDOP) and WAAS Age of Data (AOD). The HDOP should be 2 or less and the AOD less
than 15 seconds.
