Meaning
The GPS receiver is tracking satellites and sending position data to the control box in an appropriate format, but the receiver is generating and autonomous GPS position solution.
Common causes
- Base station GPS receiver configuration, power, or cables
- Base station radio configuration, power, or cables
- Machine GPS receiver configuration
- Machine radio configuration, power, or cables
- Receiver fault
Problem isolation
- Check the GPS status of any other machines on site. If these machines also show the V. Low Accuracy message (that is autonomous) also, start troubleshooting the base station.
- Verify that the machine radio has power at radio end to the rugged radio cable. Verify that the power from GPS receiver is normal.
- Verify that machine radio is synchronized to your network. If it is not synchronized correct the channel of the radio.
- If all the machine component were verified, troubleshoot the base station.
Less common causes
- Jamming of the radio. This may be caused by close proximity to a powerful transmitter such as a radio or cell tower.
- Receiving correction from someone else’s base and radio network. Unplug your base radio and see if your machine radio will synchronize. If it does, there is a duplicate of signal from another base. Change your radio network for all on-site radios.
