ASSIGNLBANDBEAM

Configure L-Band tracking

Platform:

OEM719, OEM729, OEM7500, OEM7600, OEM7700, OEM7720, PwrPak7, CPT7, CPT7700, SMART7, SMART2

This command assigns TerraStar or Veripos beams to the L-Band channels based on the defined L-Band assignment option.

Logging the ASSIGNLBANDBEAM command may not display the correct values. To access the actual beam name, frequency and baud rate values, log the LBANDTRACKSTAT log or if the beam name is known, log the LBANDBEAMTABLE log and find the associated frequency and baud rate.

Description

IDLE

0

Idle all L-Band channels

AUTO

1

The receiver searches for multiple L-Band beams on the L-Band channels based on AUTO selection criteria.

If the receiver position is known, the AUTO selection criteria is a ranking of granted access L-Band beams by descending elevation angle.

If the receiver position is not known, the AUTO selection criteria is a ranking of granted access L-Band beams in the order they appear in the stored beam table (see the LBANDBEAMTABLE log).

MANUAL

2

The receiver assigns the specified beam on the first L-BAND channel and makes the other L-BAND channels IDLE.
