STX3 - Satellite Transmitter

Powered By The World’s Most Modern Satellite Network

Globalstar has reduced the size of its Simplex Transmitter Unit (STX) by 2/3 to help customers design and build compact and efficient communications devices. Using the Globalstar Simplex data network, the STX3 allows information to be transmitted from areas well beyond the reach of reliable cellular coverage around the globe.

The STX3 provides additional opportunities to integrate satellite connectivity into products used for vehicle and asset tracking, remote data reporting and data logger reporting that have limited size requirements. Affordable pricing, low power consumption and its small size make the STX3 satellite transmitter a highly efficient device ready for integration in a wide variety of applications.

The STX3 is a low cost, OEM simplex module which sends one-way data messages via the Globalstar Simplex Network when integrated into a tracking or monitoring device. The STX3 is ideal for delivering remote sensing, tracking and monitoring applications.
