NASA satellites created to observe cyclone wind speeds and collapsing ice sheets have actually likewise shown efficient in determining the approximate areas of GPS jammers. That might assist keep an eye on high-risk locations for airplane and ships browsing the growing frequency of GPS disturbance worldwide.

2 various NASA satellite systems demonstrated how they might find a recognized however strange GPS jammer within a number of kilometers of its position in Iran, according to an experiment by Sean Gorman, CEO and cofounder of the location-based innovation business Zephr.xyz that was detailed in the publication GPS World. Such jammers utilize strong signals to subdue the weaker radio signals originating from US-operated GPS satellites and other international navigation satellite systems.

Such NASA satellites can not carry out “near-real time tracking” or identify the precise place of GPS jammers, stated Clara Chew, primary researcher and lead of the GNSS systems and information group at the California-based satellite producer Muon Space, who was not associated with the research study. Chew informed Ars that determining the approximate places of GPS jammers “might possibly be valuable for flight preparation” or for “suggesting high threat locations for maritime shipping.”

Among the NASA satellite systems, the Cyclone Global Navigation Satellite System (CYGNSS), has 8 microsatellites that spot GPS signals shown from ocean surface areas to determine wind speeds within the eyewalls of cyclones, cyclones, and tropical cyclones. When an Earth-based jammer switches on, the impact produces a big footprint in the shown GPS signals that can appear numerous kilometers from the jammer’s area.

The other satellite system, NASA-ISRO Synthetic Aperture Radar (NISAR), usually utilizes radar imaging to continuously map and track modifications throughout the Earth’s surface area, consisting of earthquakes, tsunamis, volcanoes, and ice sheet collapses. GPS jammer emissions develop streaks in the NISAR radar images that run perpendicular to flight instructions– indicating that “each streak encodes the jammer’s instructions relative to the satellite’s ground track,” Gorman composed in his GPS World short article.

“CYGNSS sees the jammer’s impact on shown GPS signals, providing an indirect measurement spread throughout numerous specular reflection points,” Gorman composed. “NISAR sees the jammer’s emissions straight in its own receiver, which is a more exact measurement, however just along the satellite’s narrow ground track.”
