SKG123NT is a high-performance GNSS timing module for the field of time synchronization. The module includes high-performance satellite receiver chip supporting GPS, Beidou, GLONASS, Galileo, QZSS, L1 + L5 dual-frequency positioning, positioning, timing function and autonomous integrity monitoring function, providing 1PPS (1Pulse Per Second) second pulse signal and PVT information output up to 10Hz.
Product Features：
◆ Support for multi-system, multi-frequency band
◆ Support for PPS time-delay adjustmen
◆ With position held, 1 star also provides a PPS
◆ ±2ns high precision pulse (PPS)
◆ PPS is associated with NMEA
◆ Supports RTCM2.3-3.3 protocol
◆ Sub-meter navigation in complex environment
◆ Industrial standard
Dimensions: 16x12mm (l x W)
Compliance with RoHS, FCC, CE
