Receiver is failing to power up

- Ensure the voltage of the power source you are using is suitable for the receiver you are powering. If unsure, please refer to the appropriate user manual free to download from the appropriate link/s from our ‘Downloads’ page

- Check polarity of power source to receiver is correct; Red to Red, Black to Black

- Check the integrity of the connecting power cables

- Check current restrictions of power source

- Connect up the power cable again and switch the receiver on

- If your receiver is still not powering, please contact a member of one of our tech support staff




Cannot get a GPS or SBAS fix

- Ensure you have a clear sky view

- Check the integrity of the antenna cables using a multimeter (For instructions on how to do this, please see Section 5 - How to test for continuity in antenna cables)

- Ensure you are well away from any nearby buildings or large objects, especially ones with metal surfaces which might be producing multi-path error.




GPS or SBAS fix is dropping out or will not lock when using a Vector Compass (VS131, VS330) or Vector OEM board (H200, H320, H321) with separate antenna’s

- Confirm that the measured antenna separation on the receiver is the same distance as the actual antenna separation from centre to centre to the cm.

- Reduce the antenna baseline to 0.5m and adjust the measured antenna separation accordingly through either your receiver interface (see below) or your receiver configuration software (e.g. PocketMax 3, SLXMon, Hyperterminal).

            Vector>Antenna Sep>Measured Antenna Separation>

- Once lock is re-acquired, you can work on increasing your antenna separation to increase heading accuracy accordingly.

- If the GPS or SBAS lock is not re-acquired, please contact a member of your dealers technical support staff.




Heading is not stable

- Ensure GyroAid and TiltAid are switched off. This can be accessed through the VS131 or VS330 LCD display:

            Vector>Aiding Features>Gyroaid-on/off

            Vector>Aiding Features>Tiltaid-on/off

- Confirm that the measured antenna separation on the receiver is the same distance as the actual antenna separation from centre to centre to the cm.

- Reduce the antenna baseline to 0.5m and adjust the measured antenna separation accordingly through either your receiver LCD interface or your receiver configuration software (e.g. PocketMax 3, SLXMon, Hyperterminal).

- Send the command $JRESET to the vector through one of the above configuration software tools.

- Once reset, allow the vector to re-initialise and re-acquire (this can take some time, typically 5-10 minutes).

- If the heading is not stabilised, contact a member of your dealers technical support staff.




Suspected Radio Frequency interference/Electro-Magnetic interference

- Ensure antenna is at a different height to any equipment e.g RADAR that may be producing RFI.

- Try moving the antenna away from such objects that produce similar frequency waves to the bands that the antenna’s operate at or any equipment that has a high electro-magnetic output.




Suspected Multi-path error

- Ensure your antenna has a clear sky view and is away from nearby buildings and large objects, especially ones with metal surfaces which might be producing multi-path error.




How to test for continuity in antenna cables

- Please follow the link below with a video on how to test an antenna cable for continuity























How do I set my receiver to use a specific differential source?

This can be completed either through your receiver LCD display (see below for instructions) or through your specified receiver configuration software.

- On your receivers display select the following:

            Differential>InUse>

- Depending on what activations are enabled on your receiver and which differential source you would like to use, cycle up or down the list and select the one you require.

- Alternatively, if you would like to disable your receiver from using certain differential sources, follow the steps below (this will not disable any activations the receiver has)

           Differential>Include>

- From there, you may configure what differential sources your receiver uses.




Not receiving L-Band differential corrections

- Ensure that your subscription to your L-band service provider is within date and has not expired.

- Validate and check the antenna connections.

- Make sure antenna’s have a clear sky view.




Am I within the closest Beacon stations coverage to receive differential corrections?

- Please follow the URL link below to identify your nearest Beacon Transmitting station and to find out wether you are within its nominal range.

                                                                      http://www.gnsspro.com/referencestations.php




Not receiving beacon corrections

- Verify you are within a beacon reference stations area of coverage and close enough to receive corrections from the station.

- Ensure there are no sources of interference nearby e.g. large metal surfaces.

- Check your antenna connection.

- Verify the MSK rate is set correctly.

- Verify the frequency of transmitting beacon.

- Select an alternate antenna position away from any possible sources of RF interference.



How to manually tune your receiver to the closest beacon station

- Once you know the transmitting frequency and baud rate (found in either of the above links) of Beacon station you would like to tune your receiver to, follow the steps below that are entered through your receiver display:

          Differential>Beacon>Configure>Tune



How to configure your receiver to automatically tune to the closest Beacon station

- Select:

          Differential>Beacon>Configure>AutoTune

- To confirm that the receiver is automatically tuning to the strongest beacon signal, select:

          Differential>Beacon>Signal Status

  1. -Next to the frequency currently tuned in there should be the letters ‘AA’ which indicate that the receiver is in an automatically tuning beacon mode as opposed to ‘MM’ which indicates that the receiver is set for manually beacon frequency input.
