Space-time safety isolation device
GNR300

GNR300 satellite space-time isolation device is a satellite signal security isolation product developed for the current BeiDou/GPS civil signal is vulnerable to interference, attack and deception, resulting in normal timing and positioning.

Product Features:

· 19-inch 1U rackmount design

· Support AC/DC redundant dual power supply

· 2-channel satellite input, 2-channel satellite output (support expansion)

· When the feeder is short-circuited for a long time, it does not damage the internal devices of the equipment

· Supports anti-forwarding, generative and intrusive signal spoofing

Main Applications:

It is suitable for electric power, operator, rail transportation, security and other industries.
