Abstract

Determining alignment and clear line-of-sight (LOS) of a satellite antenna using sensor data from an LOS sensor of the satellite antenna. Described techniques include storing first sensor data captured by the LOS sensor at a first time, the first sensor data indicating a first LOS condition of the satellite antenna corresponding to the satellite antenna having a beam LOS with a satellite of the satellite communication system that is aligned and unobstructed. The techniques may include receiving second sensor data captured by the LOS sensor at a second time after the first time, the second sensor data indicating a second LOS condition of the satellite antenna. The techniques may include determining an LOS condition change for the satellite antenna between the first time and the second time based on a comparison of the second sensor data with the first sensor data.

determining an LOS condition change for the satellite antenna between the first time and the second time based at least in part on the detection of the object.

2. The method of claim 1 , further comprising:

predicting a service interruption for the satellite antenna for communicating a communication signal with the satellite.

switching service for the satellite antenna from the first satellite to a second satellite prior to the predicted service interruption.

4. A method for use in a satellite communication system, comprising:

receiving first sensor data captured by a line-of-sight (LOS) sensor of a satellite antenna at a first time;

determining, based at least in part on the captured sensor data from the LOS sensor, that a weather event is occurring between a location of the satellite antenna and a satellite of the satellite communication system at the first time; and

adjusting a pass/fail criteria for approval of an installation of the satellite antenna at the location based at least in part on the determined weather event.

5. The method of claim 4 , further comprising:

receiving second sensor data captured by the LOS sensor at a second time after the first time, the second sensor data indicating a first LOS condition of the satellite antenna corresponding to the satellite antenna having a LOS with the satellite that is aligned and unobstructed;

determining, based at least in part on the captured second sensor data from the LOS sensor, that a weather event is not occurring between a location of the satellite antenna and the satellite; and
