- GNSS for Time Sync
Model
GT-87
- Old Products
The GT-87 supports TRAIM and various position modes, allowing it to output accurate and robust 1PPS synchronized to UTC time.
The GT-87 supports GPS, GLONASS, QZSS, SBAS.
New product: High robustness with dual frequency band reception of L1 and L5. The GT-100 can also deliver programmable frequency clock outputs.
- GNSS (Timing, Automotive/Industrial)
Features
Multi-GNSS, Concurrent reception of GPS and GLONASS
- Improved of robustness thanks to concurrent reception of GPS and GLONASS signals
- Supports concurrent GPS, GLONASS, SBAS and QZSS.
Simultaneous output of time pulse (1PPS) and low jitter clock (configurable, 4 kHz to 40 MHz) synchronized with the 1PPS
Enable to output accurate and robust UTC time and 1PPS synchronized with UTC time
- 1PPS stability: 15 nsec (1σ)
Single satellite tracking capable operations (except Navigation Mode)
Detect/Disable low integrity satellites (TRAIM function)
- Suitable for infrastructure development which needs high integrity.
Improved Noise Tolerance
Reduces effects of internal and external noise
Embedded Flash ROM
Suitable for long-term use backed by FURUNO’s continuous support and function enhancement
Enhance performance in combination with recommended antenna
AU-300 Multi-GNSS Timing Antenna delivers both high stability and high robustness.
