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 five available beams as detailed below
and, in most regions, more than one beam should be available. A global map with a beam overlay is available
f or ref erence in the
. Alternatively, the VERIPOS software
can be used to assess L-band
availability, by creating work location-specific coverage charts.
