Syntony GNSS has introduced the Echo 4RP, the latest addition to its Echo series of GNSS record and playback systems. This new model builds on the capabilities of the Echo R&P, offering advanced features designed to address the evolving needs of GNSS testing and development.

The Echo 4RP expands its frequency range to include L, S, and C bands, surpassing the previous model’s coverage of 1100 MHz to 2550 MHz. This broader spectrum supports both current and emerging GNSS and non-GNSS signals, making it adaptable for diverse testing scenarios.

The system now supports up to four RF channels for simultaneous recording and playback, an increase from three in the earlier version. This enhancement enables complex testing setups, including multi-antenna configurations and Controlled Radiation Pattern Antenna (CRPA) applications, with precise phase synchronization.

The Echo 4RP delivers high-quality signal fidelity with options for 16-bit I&Q sampling at 93.75 MHz per channel or 8-bit I&Q sampling at 187.5 MHz per channel across all four channels simultaneously. These options provide flexibility to meet specific testing requirements.

Weighing less than 10 kilograms, the Echo 4RP combines portability with performance, making it suitable for both laboratory and field environments. Its compact design simplifies deployment without sacrificing functionality.

The system includes up to 32 terabytes of internal storage with a swappable SSD design, allowing extended recording sessions and efficient data handling.

The Echo 4RP is designed for a wide range of GNSS testing applications:

• CRPA testing: Phase synchronization across all channels supports anti-jamming and anti-spoofing technologies for enhanced signal integrity.
• Multi-antenna configurations: Expanded channel capacity facilitates complex setups for developing advanced GNSS receiver architectures.
• GNSS spectrum analysis: C-band coverage allows exploration of new GNSS signals and services, aiding research into next-generation navigation technologies.
