Summary

The NewSpace Systems (NSS) GPS Receiver is a 12-channel hardware-based receiver which utilises a well-established GPS chipset.

This GPS chipset has been successfully flown by a number of organisations over many years. Targeted towards low-cost SmallSat constellations, it has been adapted for space altitude and velocity through the use of custom software modifications.

The NSS GPS includes an unregulated, isolated 28 V power input and differential interfaces. It employs latch-up detection/ protection and a watchdog timer for increased reliability and robustness.

If required by the client, the NSS team can also supply an active GPS patch antenna with the receiver. Additionally, the GPS circuitry at the heart of the receiver can also be deployed as a single mezzanine board to accompany the NSS CubeSat ACS board.

The COTS chipset utilised in the NewSpace GPS Receiver has been flying for more than a decade. Fifteen flight model units have been commissioned for build and launch in 2017 alone.

Features:

  • Hardware receiver
  • 12-channel L1 receiver
  • Small size and low mass
  • Radiation tolerant COTS
  • Simple to interface
