Change the baud rate to that which your modem supports.
How to fix Topcon HiPER GD GPS incompatible baud rate?
Change the baud rate to that which your modem supports.
What to do if Topcon GPS modem battery is low?
If the modem battery is low, attach an external power source to the receiver.
What to do if Topcon HiPER GD GPS receiver does not start data logging?
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?
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.
How to solve Topcon HiPER GD GPS receiver satellite lock issues?
If your Topcon GPS receiver takes a long time to lock onto satellites, the receiver might be storing an old almanac; update the almanac. Also, the antenna cable could be damaged; use an undamaged cable.
What to do if Topcon HiPER GD receiver tracks too few satellites?
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?
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?
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.
