GNSS INTERFERENCE DETECTION

Space-Based Intelligence to Detect, Geolocate, and Respond to GNSS Interference at Global Scale

CHALLENGE

Modern defense, intelligence, and civilian navigation systems are becoming increasingly vulnerable to GNSS interference, with both jamming and spoofing posing significant risks to flight safety, military operations, and critical infrastructure. In 2024, analysts recorded as many as 700 daily GPS jamming and spoofing incidents globally, with over 41,000 spoofing events logged in just one month1. There is an upward trend in the usage of GNSS jamming and spoofing across most of the world.

To understand GNSS Interference locations, organizations often rely on ground or airborne ISR assets. However, these systems are costly to operate, constrained by range and overflight permissions, and are susceptible to detection. Traditional outage reporting, such as ADS-B receiver-based data, only shows where signals are disrupted, not where interference originates. As a result, critical gaps remain in attribution situational awareness, and timely response.

Identifies jamming and spoofing activity at the source to enable rapid response and strategic awareness.

Supports the integrity of PNT-dependent platforms including aircraft, munitions, and C4ISR systems.

Provides precise geolocation of interference sources, not just affected areas, unlocking attribution and operational mitigation.

Contributes to Electronic Order of Battle and profiling through detailed signal characterization.

PERSISTENT MONITORING AT SCALE: Delivers wide-area coverage across expansive

Delivers wide-area coverage across expansive and strategically important regions without relying on ground-based or airborne sensors.

Activate space-based surveillance capabilities instantly for quick operational integration.

NO INFRASTRUCTURE BURDEN: Maintain data control and mission autonomy

Maintain data control and mission autonomy while relying on a secure, fully managed platform.

PRODUCT SUITE OVERVIEW

HawkEye 360’s GNSS Interference Detection product suite leverages space-based RF sensing to detect and geolocate the source of GNSS interference events such as jamming and spoofing signals, across most GNSS systems such as GPS, Galileo, and BeiDou. Using a constellation of satellites in low Earth orbit and advanced signal processing, the product delivers early-warning intelligence with high-confidence geolocation. It gives military and intelligence users the ability to locate signal denial and maintain accurate, timely situational awareness across contested environments.

CAPABILITIES

PRECISION GEOLOCATION & SIGNAL MAPPING Tri-satellite RF collection enables accurate source geolocation of GPS interference across complex and remote terrain, including terrain-adjusted elevation modeling.

SPOOFING DETECTION Advanced algorithms distinguish general

Advanced algorithms distinguish general GPS interference and spoofing activity, revealing malicious signal manipulation versus environmental interference.

BROAD AREA RF MAPPING Supports continuous RF monitoring

SOURCE-LEVEL INTELLIGENCE Unlike ADS‑B outage reports, which only show where receivers are affected, HawkEye precisely geolocates the source of interference, supporting awareness and operational mitigation.

HawkEye 360’s GNSS Interference Detection solution provides the intelligence edge in a GPS-contested world. By detecting and precisely locating jamming and spoofing events from space, it allows operators to respond decisively, plan more effectively, and maintain confidence in PNT-critical missions. Whether protecting joint forces, monitoring key theaters, or supporting early warning systems, this solution delivers unmatched insight into adversary signal denial activities, anywhere on Earth.
