Reliable & robust GNSS & GPS timing solutions

Accurate and secure GNSS time

GNSS receivers open the door to near-atomic clock accuracy for only a fraction of the cost. While providing the world’s most accurate time based on resonant frequency of atoms, atomic clocks are known to be highly expensive. GNSS receivers from Septentrio are built to receive all satellite signals from all available GNSS constellations including GPS, Galileo, BeiDou and GLONASS. These satellites are equipped with atomic clocks and continuously send timing information to the receiver. Having access to such a multitude of signals and thus timing information, allows the receiver to output highly reliable timing with sub-nanosecond accuracy. Over the last two decades Septentrio has been developing proprietary technology for resilience against GNSS jamming and spoofing, to ensure the highest level of security of its timing solutions.

Secure timing

Telecom, energy grids, broadcast equipment and other critical infrastracture relies on accurate time for synchronization. The mosaic-T GNSS module provides resilient timing for synchronizing critical applications with nanosecond accuracy. Infrastructure such as telecom towers are inherently vulnerable to GNSS spoofing due to its stationary nature. Spoofing, is a smart form of interference where the attacker sends simulated signals into the receiver, altering positioning or timing output. AIM+ anti-spoofing techniques secure Septentrio timing receivers from spoofing attacks. Additionally AIM+ anti-jamming technology protects receivers from white noise interference “jamming”or can unintentionally come from electronic devices or broadcasting equipment located around the receiver.

Time transfer and metrology

Dedicated to time and frequency transfer applications, the PolaRx5TR is optimized for quality of code and carrier phase measurements. The PolaRx5TR is fully compliant with recommendation CCTF 4 and 5 of the Consultative Committee for Time and Frequency. Its key features include:

Ultra-precise time synchronization for time transfer applications
PPS IN internal delay auto-calibration
CGGTTS V2E compliant

The PolaRx5TR receiver has proven itself as an industry benchmark for time transfer and UTC metrology. It is used by BIPM in Paris as well as in many timing labs around the world.

Radio astronomy

By simultaneously collecting data from multiple radio telescopes and combining them using a technique called astronomical interferometry, a network of telescopes can emulate a single monolithic telescope with far greater resolution than any single telescope. By synchronizing the individual radio telescopes in a network in the SKA (Square Kilometer Array) using a PolaRx5TR timing receiver, the entire network can operate similar to a single monolithic telescope with a virtual diameter of thousands of kilometers.
