Satellite Transmitter


The ST100 is the latest satellite technology introduction to Globalstar’s family of Commercial IoT Solutions. Its design is intended for rapid development by 3rd party companies and brings a low cost, reliable, complete one-way data module to the IoT market. Simply add power, set the configuration and place in a mechanical housing for a working device suited for any market.

Connectivity is powered by Globalstar’s LEO satellite constellation providing global coverage with no additional ground infrastructure required to transmit the data, resulting in reduced cost, time and effort in deployments around the world. Because the ST100 operates on the Globalstar Satellite Network, multiple country service contracts or roaming fees do not apply.

The ST100 board adds instant SATCOM capability to any OEM product with the Bluetooth and serial connector on the board and access to our APIs.

Completion rates based on Remote Telemetry Units (RTU) that are set to transmit a single packet message 3-times (the original transmission plus 2-repeats) in the frequency appropriate for the given regions. This is an estimate of coverage only. Actual Remote Telemetry coverage may vary based on terminal location, terrain features, signal strength, and other factors affecting satellite communications. Coverage may vary. Specifications subject to change without notice. This map indicates areas of potential satellite coverage only.
