ER-GM04 Features: ns level PPS accuracy 66.1x33.8mm standard size, standard 8 pin 2mm pitch Dual PPS outputs, individually configurable
ER-GM04 Full System Full Frequency Point High Precision Timing Board
ER-GM04 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-GM04 uses a new generation full-system full-frequency 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-GM04's built-in JamShield multi-frequency anti-interference module can handle narrow-band and single-tone interference, which significantly improves the reliability of timing.
