Space data used to detect sources of GPS disruptions

Radio-frequency information collected by HawkEye 360 satellites can be utilized to find GPS interference hotspots

ST. LOUIS — The proliferation of digital units designed to intervene with International Positioning System indicators is an issue for the Pentagon and for a lot of industries that rely upon GPS, as disruptions have an effect on each facet of operations. 

One of many challenges is figuring out the exact location and supply of interference, mentioned Rob Rainhart, chief working officer of HawkEye 360, a geospatial analytics firm that makes use of satellites to trace ships, automobiles or any units that emit radio frequency indicators.

HawkEye 360 is considered one of a number of distant sensing satellite tv for pc operators demonstrating their applied sciences on the 2021 GEOINT Symposium this week. 

Rainhart mentioned radio-frequency information collected by satellites can assist to find GNSS interference hotspots. GNSS is brief for world navigation satellite tv for pc system, or any satellite tv for pc constellation that gives positioning, navigation, and timing (PNT) service. 

The corporate’s satellites, geared up with software-defined radios, fly in clusters of three: one in entrance, one other behind and a 3rd that oscillates backwards and forwards. Three clusters are at present in orbit. 

Rainhart mentioned HawkEye 360 has briefed authorities and business clients involved in regards to the influence of GPS disruptions on how they may apply RF information analytics to identify interference.

The corporate has three clusters of satellites in orbit at this time and plans to launch extra, which can “allow a way more fine-tuned interference monitoring toolkit,” he mentioned.

“We’ve participated in some trials with overseas companions, taking a look at GNSS interference,” he mentioned. “There’s numerous curiosity in the issue from clients throughout the globe.”

DoD seeks proposals for detection of GNSS disruption

The Protection Innovation Unit (DIU), a Pentagon group that works with business firms, needs to benefit from the rising availability of knowledge from house and different sources to geolocate GPS interference.  

A DIU solicitation in August requested for proposals on “situational consciousness for intentional disruption of GNSS customers.” DoD is particularly eager about “persistent, large-area protection of falsified GNSS emitters that end in localized spoofing phenomenology.”

GPS indicators may be denied by digital jamming assaults. GPS customers can be attacked with falsified PNT information, a way often known as spoofing.

“Your complete world relies on GNSS-based techniques, but the GPS structure and its customers are susceptible to denial and manipulation by adversarial actors,” mentioned DIU.

Nick Estep, DIU program supervisor, mentioned the solicitation closed Aug. 23 and lots of proposals had been acquired. 

The aim is to experiment with commercially accessible information sources, each space-based and terrestrial, Estep informed table4.

“There’s an entire business sector that performs inside this area and we’re definitely intrigued to faucet into that,” he mentioned. 

An instance is the Automated Identification System (AIS) — an onboard navigation security system that transmits and screens the situation vessels at sea in actual time. “That’s a business commodity on the market that’s accessible and really has been utilized in some circumstances to characterize intentional GNSS disruptions and spoofing,” mentioned Estep.

“We’re not in search of a standard program of file,” he mentioned. “We wish to leverage all these information units and analytics which are already being utilized in a business setting or a business market, and use this to enrich the federal government capabilities.”

DIU is agnostic on which kind of knowledge or sensors are used. “There may very well be terrestrial info that informs GNSS spoofing or disruptions or it may very well be house primarily based,” Estep mentioned.

Many distributors from the house and information analytics sectors have responded to DIU’s solicitation, he mentioned. DIU will choose a number of firms this fall to make a pitch on to army clients.

“Distributors which are profitable previous part two have the chance to have interaction in govt prototypes with DIU, work with coders in a collaborative method.”

A notable problem for distributors is to indicate how they analyze information and draw conclusions from it, akin to whether or not GPS interference is being perpetrated deliberately or if it’s unintended, mentioned Estep.

“There’s several types of results, and classes of disruption, and a part of the problem that our distributors must do is to have the ability to characterize the impact and present us the boldness they’ve in what they’re seeing,” Estep mentioned. “And to indicate us you know the way you got here to that conclusion.”
