A system for measuring blockage facilitates automated measuring using an installed antenna as a measuring device, providing more accurate and reliable results as compared to conventional methods of measuring blockage. The system eliminates the need for meticulous and tedious manual measurements as well as the time consuming search for structural drawings, necessary to perform conventional blockage measuring. The system features an efficient and accurate way of establishing the angular direction points in which an antenna view is obstructed by recording the obstruction reflections standing out of the clear sky noise floor. Embodiments are particularly useful when installing a satellite communications antenna on a ship having metal structures obstructing the antenna's view such as communication masts, funnels, and smokestacks.

A method for reducing expected switchovers in antennas tracking at least one satellite. The method predicts an operation of a predetermined number of subsets of antennas during a simulated time interval. The subsets are derived from at least three antennas. Each of the at least three antennas has a field of view and is operative to selectively receive signals from and selectively transmit signals to a satellite in the respective field of view. The method determines, based on the predicted operation, an expected number of switchovers for each of the subsets during the simulated time interval. The method selects a selected subset from the subsets for communicating with the satellite. The selection of the selected subset is based on the expected number of switchovers.

Control of dual (two) antennas, for satellite communications (satcom) with satellites in one or more constellations in Low Earth Orbit (LEO) and Medium Earth Orbit (MEO). The dual antennas are typically part of a ground-based antenna system, in particular using the Satrack single pedestal with split antenna design, housed efficiently under a compact radome. Features simultaneous pointing toward two separate satellites during the satellites' handover/switching periods with instantaneous transition between the satcom modems for assuring real-time, continuous data communication over a LEO/MEO satellite link. The dual (two) antennas system can also be used in a 'monopulse/electronic scan' mode where a first antenna is used for tracking according to ephemeris data, while a second antenna on the same pedestal will scan for offset/compensation to the first antenna path.
