From its RF components through its software, Syntony built Echo R&P to provide the most accurate recording and reproduction of reality available, and to give testers enough space to store a large sample of the real world. In particular, Echo R&P is used to test very demanding and mission critical GNSS receivers for the aerospace industry.

• 2 separate machines: one for recording, one for replaying
• 3 RF channels of 200 MHz bandwidth each (for the whole set of GNSS signals from all constellations),
• 16-bit resolution (I&Q)
• from 7 to more than 1000 hours of record/replay capabilities depending on configurations.
