Troubleshoot the GPS input
From Nuno Navigator
After a few minutes if Nuno Navigator is still searching for your GPS follow the steps detailed below:
- Check you have switched your GPS on.
- Check that your GPS is configured to output NMEA 0183.
- Check that your GPS is configured with the following
- 8 data bits
- No parity
- One of these baud rates:
| 4800 |
| 9600 |
| 14,400 |
| 19,200 |
| 38,400 |
| 56,000 |
| 57,600 |
| 115,200 |
| 128,000 |
| 256,000 |
- Check that the wiring between your GPS and your computer is secure.
- Check that any additional interface box (such as an optical isolator or data concentrator) is switched on and has power connected (if its power is not derived from a computer USB connection).
- Install any software drivers that came with your GPS.
- Check that no other running applications are using the port that the GPS is connected to.
- Check that your GPS is configured to output positions using the WGS84 horizontal datum. This may be referred to as "Hor Datum" or "Map datum" in the GPS configuration.
