Features

Concurrent reception of GPS and GLONASS

Improves robustness of the timing data thanks to concurrent reception of GPS and GLONASS
Supports GPS, GLONASS, SBAS and QZSS. Galileo Ready

Suitable for LTE-Advanced small cellular base stations

Twice the number of satellites in view than with GPS-only positioning only thanks to Multi-GNSS
Enables to output accurate and robust UTC time and 1PPS from receiving much more satellites even in deep urban canyons
Suitable for LTE-Advanced small cellular base stations

Easy to replace with Motorola M12M device

Supports M12 binary protocol as well as identical footprint to the Motorola M12M device

Time Pulse Output

Enable to output accurate and robust UTC time and 1PPS synchronized with UTC time

1PPS accuracy: < 15 nsec (1σ) (@ -130 dBm)

One satellite tracking is enough to output precise 1PPS

TRAIM Function

Detect low-integrity satellite and satellite not to use for positioning

Suitable for infrastructure development which needs high integrity

Position Mode

Selectable Position Mode based on use case

Position Hold Mode
Position Survey Mode

Improved Noise Tolerance

Reduces effects of internal and external noise

Active Anti-Jamming
Advanced Multipath Mitigation

Fast TTFF

Selectable appropriate method for fast TTFF

Hot start: <5 sec (Typ.)
Cold start: 35 sec (Typ.)

Data Output Format

M12 Binary

Ready for New Positioning Systems

Galileo E1B/E1C
QZSS L1S

Embedded Flash ROM

Suitable for long-term use backed by Furuno’s continuous support and function enhancement
