Space Data Used to Detect Sources of GPS Disruptions

One of the challenges is identifying the precise location and source of interference, said Rob Rainhart, chief operating officer of HawkEye 360, a geospatial analytics company that uses satellites to track ships, vehicles or any devices that emit radio frequency signals.

HawkEye 360 is one of several remote sensing satellite operators demonstrating their technologies at the 2021 GEOINT Symposium this week. 

Rainhart said radio-frequency data collected by satellites can help to locate GNSS interference hotspots. GNSS is short for global navigation satellite system, or any satellite constellation that provides positioning, navigation, and timing (PNT) service. 

The company’s satellites, equipped with software-defined radios, fly in clusters of three: one in front, another behind and a third that oscillates back and forth. Three clusters are currently in orbit. 

Rainhart said HawkEye 360 has briefed government and commercial customers concerned about the impact of GPS disruptions on how they could apply RF data analytics to spot interference.
