What to do if Topcon HiPER GD receiver does not power up?
- L
  Linda StephensAug 23, 2025
  If your Topcon GPS receiver isn't powering on, there might be a few reasons. First, the receiver could be in Zero Power Mode; try pressing the Reset key. If you're not using an external power source, the batteries may be discharged, so connect a fully charged external power source. If you are using an external source, the internal batteries might be drained; charge them overnight. If the issue persists after charging, the charger or internal batteries could be defective. In this case, contact TPS Customer Support for advice.

What to do if Topcon HiPER GD GPS receiver does not start data logging?

  Jennifer HernandezAug 29, 2025
  If your Topcon GPS receiver isn't starting data logging, it could be due to a lack of free space for files; download receiver files to a computer and delete files. Alternatively, the receiver may have already logged 512 files into the internal memory; delete unnecessary files.

Why does Topcon HiPER GD have poor satellite geometry?
- B
  Blake MillerAug 28, 2025
  Poor satellite geometry (high PDOP/GDOP values) in your Topcon GPS can stem from several causes. The elevation mask might be above 15 degrees; lower the elevation mask. There may be a poor connection between the receiver and antenna; ensure the cable is undamaged and securely connected. The Base and Rover modems could be set to different radio channels; set them to the same channel. Finally, a discrepancy might exist between the differential standards used at the Base and Rover receivers; ensure they use the same corrections input/output format. Connect your receiver and a computer and start PC-CDU. Click Configuration->Receiver ->Ports and set the same input/output format for both receivers.

What to do if Topcon HiPER GD receiver tracks too few satellites?
- Z
  zbennettAug 27, 2025
  If your Topcon GPS receiver is tracking too few satellites, it could be due to a high elevation mask value; lower the elevation mask. Alternatively, the survey might be conducted near obstructions. In this case, check that the Multipath Reduction boxes have been enabled. Connect your receiver and a computer and start PC-CDU. Click Configuration ->Advanced->Multipath Reduction and enable the two boxes. Consider moving to an area free of obstructions.

Why my Topcon HiPER GD GPS receiver cannot obtain Code Differential or RTK solutions?
- J
  juarezdianaAug 26, 2025
  If your Topcon GPS receiver is failing to obtain Code Differential and/or RTK solutions, several factors could be responsible. An improper receiver status may have been chosen; ensure the receiver has the correct status (kinematic, RTK, or static). The corresponding receiver options may be disabled or expired. Also, there might not be enough common satellites; the Base and Rover should track at least five common satellites, so ensure that both the Rover and Base receivers use the same, and updated, almanac and check the elevation masks of the Rover and Base receivers; they should be the same.

How to fix Topcon HiPER GD GPS receiver connection issues with a computer?
- A
  Andres BeckerAug 25, 2025
  If your Topcon GPS receiver won't connect to a computer or external controller, consider these potential causes. The Daisy Chain mode might still be active. The cable may not be properly plugged in; ensure it's securely connected to the correct serial port. A damaged cable could also be the culprit; try using an undamaged cable. Finally, the receiver port used for connection may not be in Command mode. Connect your receiver and a computer using a free port and start PC-CDU. Click Configuration->Receiver ->Ports. Change the Input for the serial port used for connection to Command.
