NASA satellites designed to observe cyclone wind speeds and collapsing ice sheets have also proven capable of identifying the approximate locations of GPS jammers. That could help monitor high-risk areas for aircraft and ships navigating the growing prevalence of GPS interference worldwide.<\/p>\n
Two different NASA satellite systems showed how they could locate a known but mysterious GPS jammer within several kilometers of its position in Iran, according to an experiment by Sean Gorman<\/a>, CEO and cofounder of the location-based technology company Zephr.xyz<\/a>\u00a0that was detailed in the magazine GPS World<\/a>. Such jammers<\/a> use strong signals to overpower the weaker radio signals coming from US-operated GPS satellites and other global navigation satellite systems.<\/p>\n Such NASA satellites cannot perform \u201cnear-real time monitoring\u201d or pinpoint the exact location of GPS jammers, said Clara Chew<\/a>, principal scientist and lead of the GNSS systems and data team at the California-based satellite manufacturer Muon Space, who was not involved in the study. But Chew told Ars that identifying the approximate locations of GPS jammers \u201ccould potentially be helpful for flight planning\u201d or for \u201cindicating high risk areas for maritime shipping.\u201d<\/p>\n
