Echo R™ is the highest fidelity GPS/GNSS recorder in the world.

It captures the entire GNSS band, perfectly.

Able to record:
- up to 16-bit I&Q
- at up to 200 MHz sampling rate
- on 3 RF channels simultaneously,
it captures even the smallest imperfections of real life.

Echo R™ is used by major aircraft manufacturers for flight tests, but also for recording from cars, trains, boats.
Its performance allows researchers on scintillation, multipath and agriculture to collect data they can trust.

The recorded IQ samples can be processed manually or replayed by Echo P™.

Record simulated signals from in the lab 



Echo P™ is the highest fidelity GPS/GNSS Playback system in the world.

It captures the entire GNSS band, perfectly.

Able to replay:
- up to 16-bit I&Q
- at up to 200 MHz sampling rate
- on 3 RF channels simultaneously,
it replays even the smallest imperfections of real life.

Echo P™ can replay Echo R™ recording perfectly but can also be used independently.

It can be used as a simple multi-constellation, multi-frequency test system in production.

The finest GNSS playback system in the world
For R&D and Production

Choose the best recorder & playback solution for GNSS signals

Echo R&P

Whether developing new components, improving algorithms or working on the integration of an entire receiver system, Echo™ GNSS Recorder is the perfect fit for your testbed environment.

Echo™ singularity lies in the alliance of SDR (Software Defined Radio) and a state of the art RF Analog front-end.

Top-end processing performance and superior RF quality are now met into a COTS appliance with utmost flexibility in recording control.
