How to Troubleshoot the GPS in a Konsberg System

Konsberg develops global positioning systems for commercial and recreational boats. The typical applications for a GPS tracking system that Konsberg uses are seismic survey and AIS position tracking. The GPS is available in the Seatrack 330, 320 and 220. The GPS systems are designed for harsh environments and to withstand large shocks without failing. But the manual that comes with the systems offers many techniques you may need for troubleshooting if you run into problems.

Things You'll Need

• The Seatrack Manual

Instructions

1. Turn the power off by removing the power cable if you are having trouble turning the Seagate GPS on. Wait a minute or so, and then reconnect the power cable. In addition, check to make sure that the power supply outputs are 9 to 13 V DC, which is the correct voltage for the outputs.

2. Check and make sure that the Seatrack units are correctly configured and that the time is synchronized if you are experiencing communication problems. The GPS will not function properly if the time is not synchronized. Make sure the power is connected and the HHT has external 5 V DC power. Once you have typed the password into the setup menu and the unit's identification number, a menu page should appear. Check and change the following configuration parameters: • Period. Press Enter. The new configuration will not be stored until Enter is pressed. After configuration has completed disconnect the power and the HHT.

   If you are configuring using a PC, connect the power to a PC unit, then start "hht.exe" or "WinHHT.exe" on the PC. Press the character code "ABCDEFGHIJ" to go from normal data transmittal mode to HHT mode. Type the password to enter the setup menu. Configure the unit to: * Period. Then hit enter. Once the configuration is complete, disconnect.

3. Turn the power off if the GPS will not fix on a position or there is no GPS data. Remove the power cable. Reconnect the power cable and turn on. Then, reset the GPS receiver by pressing the "R" button and select 2 on the terminal, which should fix the position.
