Introduction

ER-GB-04 Full System Full Frequency Point High Precision Timing Board

Introduction

ER-GB-04 Full System Full Frequency Point High Precision Timing Board is a ns-class high-precision timing board that supports GPS/GLONASS/BDS/Galileo and other full-system satellite signals.

ER-GB-04 uses a new generation full-system, full-frequency and high-precision SoC chip-Nebulas-II, which supports 432 super channels, and can simultaneously track full-system full-frequency satellite signals such as BDS, GPS, GLONASS, Galileo, and significantly improve the stability of timing. The ER-GB-04 built-in JamShield multi-frequency anti-interference module can handle narrow-band and single-tone interference, which significantly improves the reliability of timing.
