Syrlinks Releases A New Generation High-End GNSS Receiver N-SPHERE，which Provides Accuracy Better than 0.5 meters
Syrlinks, a leading company in the design of RF Communication systems for Space releases the N-SPHERE, a new High-End GNSS Receiver for nano and cube satellites.
N-SPHERE comes as a new generation of Syrlinks’ GNSS receiver. It's SDR (Software-Defined-Radio) core architecture implements the latest state-of-the-art positioning and synchronization techniques, to reach top-class of performances for Real-Time Precise Onboard Orbit Determination (P2OD) and accurate time synchronization.
“We are very proud to release N-SPHERE at IAC 2022. There is today a growing demand expressed by satellite operators for advanced GNSS functionalities such as sub-metric satellite positioning as well as Precise Orbit Determination,” says Eric PINSON, Director of Space activity at Syrlinks.
N-SPHERE inherits from more than 10 years of Syrlinks’ experience in the GNSS domain and has been jointly designed with CNES (The French Space Agency). As a must-have, the receiver supports GNSS multi-constellations and multi-frequencies. Indeed, it synchronizes with different GNSS systems including GPS, GALILEO, BeiDou, and GLONASS. Its synchronization process is GALILEO autonomous with no need for GPS pre-synchronization.
In terms of positioning, N-SPHERE provides accuracy better than 0.5 meters, thanks to a unique P2OD library (referenced as “Bolero”) developed by CNES. Its Software-Defined-Radio (SDR) core architecture brings maximum flexibility and authorizes in-flight firmware upgrades or software configuration adjustments.
N-SPHERE takes part in the GOMX-5 mission organized by ESA and GomSpace A/S, to be launched in 2023. The product is integrated within a 12U Nano/Cubesat payload to demonstrate new nanosatellite capabilities for the next generation of LEO constellations.
“GOMX-5 is a great opportunity to illustrate the in-space capabilities of next-generation Low-Earth Orbit nanosatellites such as the GNSS functionalities with N-SPHERE. N-SPHERE’s SDR platform comes as a very future-proof and scalable solution that authorizes the next level of GNSS signal protection with anti-jamming and antispoofing mechanisms”, adds Eric.
