Timing Multi-GNSS Receiver Module GT-90/GT-9001

A next-generation single-band (L1) GNSS receiver module for time synchronisation, compatible with all global GNSS systems. It supports widely used L1 antennas, making it ideal for cost-sensitive applications and seamless upgrades from existing systems, while achieving class-leading stability of less than 4.5 ns (1σ) under open sky.

GT-9001 adds clock output, short-term holdover and external clock input; GT-90 provides 1PPS output.

Key Features

  • Supports major global GNSS constellations (GPS, GLONASS, Galileo, BeiDou, QZSS, SBAS).
  • Delivers high-resolution, UTC-synchronised 1PPS (GT-9001 also supports clock output).
  • World's highest stability — less than 4.5 ns (1σ) under open sky.
  • Compliant with ITU-T G.8272 PRTC-A and PRTC-B (TDEV/MTIE).
  • World's lowest accuracy degradation in harsh urban multipath environments.
  • Anti-jamming and anti-spoofing with real-time notification.
  • Signal authentication (OSNMA / QZNMA) from Galileo and QZSS.
  • GT-9001 adds short-term holdover and external clock input.
  • Carrier-grade quality, suitable for critical infrastructure applications.
