The following are fundamental benefits which flow from eSAT’s use of GEO satellites as its space platform for IoT connectivity:
There is no need for new constellations of satellites to be developed, manufactured, launched, and supported. The GEO MSS satellites that eSAT will be utilizing are in orbit, on station, with proven reliability records. Thus, eSAT has no need to raise tens or hundreds of millions of dollars to build the space segment for the system, which already exists and operates extremely well. Further, when eSAT begins commercial service the coverage will be immediately extendable to the entire planet (excluding the high polar regions).
The potential for either RF or physical interference among different MSS satellites is strictly managed and controlled under a regulatory framework that is well understood and respected internationally. LEO operators are finding that they must contend with one another as well as legacy users of spectrum and spatial orbits before they will have a clear picture of their operating status.
Among other benefits this constancy of communication links permits low latency for alarms generated at the terminals, or for commands sent to them. LEO systems suffer delays because of gaps of coverage between the rapidly moving satellites which move into and then out of the field of view of the terminals. These gaps are especially long (sometimes hours) in the first years of deployment when full LEO constellations have not been completed.
