IʼM A NOVICE:
A. Apply power to the receiver
B. Check $JAPP to ensure RTK application is running
C. Check $JK to ensure the subscription code is ready to work as an RTK rover (3008 or
Higher)
D. Ensure the corrections are being received on a receiver port in either DFX format at the
correct baud rate
E. Monitor the quality indicator, correction age, and reference station ID number in the
GPGGA message for performance. Monitor the standard deviations of latitude, longitude,
and height from the GPGST message to determine positioning accuracy.
WALK ME THROUGH IT SLOWLY:
1. Place the GPS antenna outside in an open area where it will be able to track as many
satellites as possible.
2. Connect the antenna to the antenna cable, and then connect the cable to the receiver.
3. Apply power to the receiver.
4. Connect your PC COM port to the receiverʼs port. Port A will be used in this workflow.
5. Select software to communicate with the Crescent based receiver. SLXmonDF or
HyperTerminal can be used, along with other choices. If you have trouble connecting,
ensure you are selecting the right port and baud rate, and ensure the correct cables are
connected properly.
6. Once connected, from a screen that allows commands to be sent to the receiver, send a
$JAPP command. The response may be like this:
