Checking L-band Beam
L-band beam tracking is required to receive VERIPOS correction service data. The beams in use on the LD900L model will be shown on the Status page:
The beams in use on LD900 and LD900M models can be found by checking Corrections > VERIPOS from the Status page:
Changing L-band Beam
To change L-band beam navigate to Corrections > L-band > Beam:
The LD900 receiver supports multi-channel L-band tracking, providing reception of services from up to three satellites broadcasting VERIPOS corrections simultaneously. This reduces the risk of satellite masking or blocking and ensures continuous reception of VERIPOS correction services. Auto is the recommended selection, as this will automatically select the three highest elevation L-band beams for your location. When this mode is selected, the LD900 will use all correction data received from each L-band satellite in the position calculations.
If required, the user can select a specific L-band beam. VERIPOS have six available beams and in all regions, more than one beam should always be available:
Note: The VERIPOS software Verichart can be used to assess L-band availability, by creating work location-specific coverage charts.
