NAVICECUTOFF

Sets elevation cut-off angle for NavIC satellites

Platform:

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

This command is used to set the elevation cut-off angle for tracked NavIC satellites. The receiver does not start automatically searching for a NavIC satellite until it rises above the cut-off angle (when satellite position is known). Tracked satellites that fall below the cut-off angle are no longer tracked unless they are manually assigned (see the ASSIGN command).

In either case, satellites below the NAVICECUTOFF angle are eliminated from the internal position and clock offset solution computations.

This command permits a negative cut-off angle; it could be used in these situations:

• The antenna is at a high altitude, and thus can look below the local horizon

• Satellites are visible below the horizon due to atmospheric refraction

Care must be taken when using NAVICECUTOFF command because the signals from lower elevation satellites are traveling through more atmosphere and are therefore degraded. Use of satellites below 5 degrees is not recommended.

Use the ELEVATIONCUTOFF command to set the cut-off angle for all other systems.

For dual antenna receivers, this command applies to both the primary and secondary antennas.
