With over half a century of experience and the engineering excellence founded in its COMSAT heritage, IOT Systems provides clients with the products and expertise to effectively manage their satellite communications services.

Standard In-Orbit Test System
The Standard In-Orbit Test System provides satellite operators and manufacturers with in-orbit spacecraft transponder measurements, processing and control software, and proven hardware design. By using commercial, off-the-shelf hardware and easily customized descriptive data files, IOT Systems is able to deliver high-quality, field-tested in-orbit test systems against tight schedules.

In-Orbit System functions include in-orbit acceptance testing, routine payload monitoring, and anomaly investigation. The standard in satellite payload in-orbit test (IOT) systems.

IOT Systems has successfully used Standard In-Orbit Test System methods on all of the DIRECTV, Galaxy, SBS, Sirius Satellite Radio, HotBird, Eutelsat II satellites, as well as the AMSC and ACeS mobile satellites.

Antenna Verification Program
The Antenna Verification Program, developed by IOT Systems personnel under then COMSAT Laboratories, provides an accurate and efficient method for verifying the performance of earth station antennas.

The AVP system measures antenna parameters such as radiation patterns, gain, system temperature profiles, radio star gain-to-noise temperature ratio (G/T) and gain, cross-polarization isolation contours, and effective isotropically radiated power (EIRP) stability. A personal computer using Microsoft Windows is used to monitor, control and record data from a variety of commonly available test equipment.
