Rohde & Schwarz offers multi-antenna GNSS sat nav tests




GNSS receivers are able to process signals from diverse navigation systems such as GPS, Glonass, Galileo or BeiDou in several frequency bandsĀ in order to improve positioning accuracy.

This can often require systems with several antennas operating in parallel.

Accuracy can be further improved with differential GNSS (DGNSS) techniques. These techniques are used in applications such as autonomous driving.

To test multifrequency and multi-antenna systems, users now have access to 72 GNSS channels that can be assigned to up to four RF outputs.

The R&S SMW200A can generate QZSS and SBAS signals as well as GPS, Glonass, Galileo and BeiDou signals.

It has an internal noise generator and can generate complex interference scenarios with multiple interferers. And GNSS, noise and interference signals are generated directly in the instrument.
