GNSS SDR Front End and Receiver
NSL's software defined radio technologies have the capacity to digitize, acquire and track satellite signals from the full complement of GNSS systems, including GPS, Galileo, GLONASS, Compass, EGNOS, GAGAN, MSAS and WAAS.

We have developed different flavours of Front End, predominantly for R&D and prototyping purposes. Our first initiative, called Primo, is a single frequency L1 front end capable of GPS, SBAS, Galileo or Glonass FDMA. Primo II is a dual RF FE board allowing all frequencies across the GNSS Upper L-Band (ie GPS and Glonass) and Selecta is a single FE configurable to any RNSS frequency.

By combining the best features of these products we created Stereo, a fully flexible dual-board GNSS RF FE.
Stereo contains two FEs, one covering the Upper L-Band and the other covering the full RNSS spectrum allowing the following signals to be tracked and acquired:
  • GPS L1/L2/L2C/L5
  • Galileo L1/E5a/E5b/E6/AltBOC
  • GLONASS G1/G2/G3
  • Compass B1/B2/B3
Stereo can be purchased from NSL with ordering information and pricing at the following page.

NSL's vehicle based OBU has been developed for road charging pilot studies. The software receiver's acquisition and tracking engine uses high sensitivity techniques and accepts ephemeride assistance data. The software receiver's positioning engine includes our advanced RAIM integrity techniques.

JINGO is a jamming and interference based on the Selecta FE and allows users to identify and isolate both natural and deliberate GNSS interference.

SNAP is an E5 GNSS receiver with the additional capability of receiving messages E5 pseudolite signals and messages.
