Echo™ 4RP: The Next Evolution in GNSS Recording & Playback
Syntony GNSS, as a leader in software-based navigation and positioning solutions, has unveiled its latest innovation: the Echo™ 4RP, an advanced GNSS recorder and player designed to meet the evolving demands of GNSS testing and development. Building upon the robust foundation of its predecessor Echo™ R&P, and with the support of the CNES, the Echo™ 4RP introduces significant enhancements that cater to the intricate requirements of modern GNSS applications.
Advanced Features and Upgrades
The Echo™ 4RP pushes the boundaries of GNSS recording and playback technology with several key upgrades:
- Enhanced Multi-Channel Support – The Echo™ 4RP now supports up to four RF channels for both recording and playback, up from three in the previous generation. This improvement enables complex multi-antenna configurations, precise Controlled Radiation Pattern Antenna (CRPA) testing, and more advanced GNSS signal evaluations.
- Extended Frequency Range – Covering L, S, and C bands, the Echo™ 4RP surpasses the previous Echo™ R&P, ensuring compatibility with current and future GNSS signals while offering a future-proof testing platform.
- Superior Signal Fidelity – The system supports 16-bit I&Q sampling at 93.75 MHz per channel or 8-bit I&Q at 187.5 MHz per channel, providing unparalleled accuracy in GNSS signal capture and playback.
- Increased Storage Capacity – With up to 32 TB of internal storage and a swappable SSD design, users can conduct long-duration recordings without compromise.
- Compact and Portable – Weighing under 10 kg, the Echo™ 4RP is built for both lab and field environments, offering a high-performance solution in a portable format.
Joël Korsakissok, CEO of Syntony GNSS, highlights the significance of these advancements:
“Echo™ R&P was already the recorder and replayer with the best signal fidelity on the market, and we are proud to push the limits even further with the Echo™ 4RP. With this new generation, we are not only enhancing signal fidelity and channel capacity but also addressing key market demands. Our customers have long requested a versatile solution, capable of being used in very diverse cases, needing very high throughput, 4 channels or more, phase synchronization, and extended frequency band support asked by new PNT signals, and segments, like LEO or moon PNT, and we are very happy to propose it now.”
Versatile Applications & Continued Support for Existing Solutions
The Echo™ 4RP is engineered to support a wide array of applications, making it an essential tool for GNSS researchers, engineers, and developers.
- CRPA Testing – With precise phase synchronization across all channels, the Echo™ 4RP is ideal for anti-jamming and anti-spoofing validation.
- Multi-Antenna and Multi-Receiver Configurations – Its expanded channel capacity ensures compatibility with advanced GNSS receiver architectures, enhancing development for autonomous vehicles, precision agriculture, and defense applications.
- Comprehensive GNSS Spectrum Analysis – The system’s broadband coverage allows for the exploration of new GNSS signals and services, supporting both R&D and regulatory compliance efforts.
While the Echo™ 4RP represents the cutting edge of GNSS recording and playback technology, Syntony GNSS recognizes that certain customers still rely on previous-generation solutions. Therefore, the company continues to offer its Echo R, Echo P, and Echo Handheld Recorder on special request, ensuring flexibility for various project needs.
