Product Overview

Produces reliable GPS L1 signals to external receivers in a situation where receiving GPS signal is not reliable due to disturbance of signals such as GPS Jamming, GPS Spoofing, etc.

Transmits local GPS signals to external receivers during normal use, and produces self-created GPS signals to external receivers when Jamming or Spoofing is detected. In order to maintain accuracy of output signals, it uses KRF-T1/E1 and IS2000GPS information.

GCTS-800 is consisted of GPS signal processing unit (IF/RF up conversion module) and GPS receiving antenna, which allows it to continuously produce reliable GPS signals in conditions where GPS receiving is disturbed. Such technology is extremely useful as there is continuous disturbance on GPS signals from North Korea.

Also, the equipment is linked to GPS server such as PTP GrandMaster to generate and output GPS signal, which allows reception of GPS signal disregarding the shaded areas.
