LabSat Product Manager in an interview with Coordinates

‘LabSat 3 WIDEBAND can handle almost any combination of constellation and signal that exists today’. Could you please explain this briefly?

LabSat 3 Wideband is an RF signal record and replay system with three independently tuneable wideband channels which can be adjusted to operate anywhere in the L-Band GNSS range. A powerful web-based graphical interface gives users the power to adjust quantisation, bandwidth and individual channel frequency. This allows for the capture and replay of most GNSS signals and even a few non-GNSS signals.

What are the advantages of LabSat 3 over its predecessors?

LabSat 3 and LabSat 3 Wideband are compact, self-contained, battery-powered devices that can easily fit into a backpack for mobile GNSS recording. Both devices are available with three RF channels allowing a minimum of 3 constellations to be recorded and replayed. LabSat 3 Wideband can record up to 56MHz bandwidth on each of its RF channels allowing multiple constellations to be recorded in each channel.

What are the key features of SatGen software?

SatGen software allows the user to create a GNSS RF I&Q or IF data file that can be replayed on a LabSat providing true multi-constellation simulation capability. SatGen can generate static position simulations or scenarios which are based on a user-generated trajectory file. SatGen compliments the LabSat range of GNSS simulators, and is available in single, dual, triple and multi-frequency/ multi-constellation versions.

How do you see the growth of GNSS simulators market in years to come?

With the boom in wearable devices and autonomous transport we expect to see an increase in all areas of testing from R&D through to production testing. As manufacturing volumes of GNSS enabled devices increase, so the need to test with equipment which produces consistent and repeatable RF signals becomes more pressing. Simulators and record and replay devices are essential in minimising time to market and maximising endof- line production quality. We are positive about the growth of the GNSS simulator market and think it will continue to grow and prosper in the years to come.
