Safran DSI - N-Sphere GNSS Receiver
- High Reliable New Space Design
- 5 Year Life-Time LEO Missions
- Multi-Constellation (GPS, GALILEO, BeiDou, & GLONASS) / GALILEO Autonomous
- In-Flight Firmware Uploading
N-SPHERE comes as a new generation of Space GNSS receiver, optimized for a smooth integration within Nano and Cube satellites. It implements the latest state-of-the-art positioning and synchronization techniques, to reach top-class performances for Real-Time Precise Onboard Orbit Determination (P2OD) and accurate time synchronization in space.
The receiver can synchronize from different GNSS systems including GPS, GALILEO, BeiDou and GLONASS. Its synchronization process is GALILEO autonomous with no need of GPS pre-synchronization. In terms of positioning, N-SPHERE provides accuracy better than 0.3 meters, thanks to an Onboard Orbital Navigator (referenced as “Bolero”). Its Software-Defined-Radio (SDR) core architecture brings maximum flexibility and authorizes in-flight firmware upgrade or software configuration adjustment.

Intrinsically safe reed relays and optocouplers are engineered for use in hazardous environments where ignition prevention is critical. Certified to ATEX standards and tested to ensure they do not become ignition sources, even in the presence of short circuits or adjacent component failures—these components are ideal for applications in explosive atmospheres such as mining, chemical processing, refineries, and power stations.
Designed to meet EN50020 safety standards, these relays and optocouplers feature tightly controlled air and creepage paths, high dielectric strength, and low-voltage coil inputs. With a maximum peak voltage of 375 V across input and output, and isolation distances up to 10 mm, they ensure safe operation under overload conditions. The Comparative Tracking Index (CTI) of the plastics used exceeds 175, and internal potting compounds provide additional insulation for long-term reliability.
