GPS signal jammers are becoming more important in a country

North Korea is apparently active jamming GPS signals using truck-mounted systems that overrun signals coming from tracking satellites. South Korea is unable to pinpoint the locations of these GPS jammer because the Army runs them for about ten minutes at a time and then moves them.

This is the fourth round of GPS jammer by North Korea since 2010. Previous attacks have affected approximately 1,000 civil aircraft and unmanned aerial vehicles of the South Korean military. An attack in 2012 reportedly affected GPS-based car navigation systems in the capital city of Seoul.

GPS Jammer is designed for area and assets protection against satellite navigated threats like GPS guided missiles. The SCL-APSNT can also be used against low flying UAVs to prevent reconnaissance of important place. GPS jammer can be effectively used in combat situations for eliminating satellite navigated guided weapon systems, missiles and ground/airborne threats It is designed to operate on all satellite navigation system available today or in the near future including GPS, GPS II, GALILEO and GLONASS at different power levels. It is upgradable to operate on COMPASS. (SCL-APSNT) provides protection ranges from 30 Km to 150 Km depending on the power output of the jammer and the envisaged region of coverage.

GPS disruption isn’t limited to jamming, either. There are increasing reports that the Russians have been expanding their ability to spoof the system’s signals, point receivers at the wrong locations. In June 2017, we reported on the U.S. Maritime Administration’s report about such incidents in the Black Sea in which ships’ navigation equipment was showing their location miles inland. Other reports of location errors had earlier cropped up in Moscow among players of the popular cell phone game Pokemon Go, which relies on a mobile device’s GPS-enabled location services.

The event did not go unnoticed in Israel, which has for years feared but simultaneously prepared for the possibility that—in a future conflict with Hezbollah in Lebanon, Hamas in the Gaza Strip, Syria or Iran—its GPS-guided weapons will fail. The IDF has taken into consideration the possibility that North Korea has sold its GPS jamming system to countries in the Middle East including Lebanon, Syria, and Iran.
