Delphi DS101 High-value Satellite Modem

Delphi's DS101 is a proven, two-way satellite modem designed for use with the ORBCOMM low-earth orbit (LEO) satellite network. Enabling remote asset tracking, monitoring, and control globally, it was specifically developed for the machine-to-machine (M2M) market with state-of-the-art, automotive-grade quality.

The DS101 offers:

  • Robust sensitivity and interference rejection
  • Low power consumption (< 45mA receive mode)
  • Open drain UART interface
  • Standard header to help keep integration costs low
  • VSWR detector to simplify support and maintenance of deployed units
  • Easy integration into your application


A high-performance satellite transceiver, the DS101 satisfies the need for "modem only" applications. With a small footprint, efficient power consumption, globally-competitive pricing, and world-class design and performance, the DS101 is ideal for applications that require reliable, low-cost data communication from even the most remote locations around the world. 

Current Applications

  • Automatic meter reading
  • Transportation tracking
  • Oil and gas monitoring
  • Security

In addition, the DS101 is ideally suited for integration with widely-available terrestrial modems to provide a cost-effective, dual-mode solution.
