(Photo: Septentrio) Septentrio has launched the mosaic-T GPS/GNSS receiver module, built specifically for resilient and precise time and frequency synchronization under challenging conditions. According to the company, its multi-frequency, multi-constellation GNSS technology — together with AIM+ Advanced Interference Mitigation algorithms — allows mosaic-T to achieve maximal availability even in the presence of GNSS jamming or spoofing. This compact surface-mount module is designed for automated assembly and high-volume production. “We are excited to expand our mosaic GNSS module family with mosaic-T, which will provide critical infrastructure and mission-critical PNT applications with accurate, reliable and resilient timing solutions,” said Francois Freulon, head of product management at Septentrio. Septentrio mosaic-T delivers timing with nanosecond-level accuracy and has additional inputs for an external high-accuracy clock, the company added. Septentrio, headquartered in Leuven, Belgium, designs and manufactures multi-frequency multi-constellation GPS/GNSS positioning technology for demanding applications.
