What UHU Technologies does

UHU Technologies, LLC is a privately-held engineering research and development company founded in 2013 and headquartered in Richardson, Texas. The company designs hardware systems that detect and mitigate GPS spoofing and jamming attacks targeting critical civilian and military infrastructure, using patented angle-of-arrival spatial processing techniques borrowed from the Signals Intelligence (SIGINT) discipline. Unlike competing approaches that rely on navigation-message analysis, multi-GNSS redundancy, or alternate time sources, UHU computes the angle of arrival for each received GPS signal and compares it to known satellite positions — the only signal feature that cannot be spoofed — and then spatially nulls attacker signals.

The product portfolio is organized into two GPS product lines and a complementary antenna product line. The Northstar GPS Health Monitor is a 1U rackmount detection system paired with a 4-element GPS antenna array that identifies spoofing or jamming within seconds and presents a web-based GUI with constellation, map, and spectral views plus historical time-machine analysis. The UHU1000 GPS Threat Mitigation System extends these capabilities into active mitigation, pairing a 7-element antenna array with spatial nulling to preserve GPS-derived position and time in denied environments while performing NAVWAR missions to geolocate attackers. The UAN antenna series (UAN0101 omni for airborne S/C-band, UAN0201/UAN0202/UAN0204 blades for communications, SIGINT, C-Band, and GPS L1/L2 bands) is supported by in-house manufacturing including a Satimo SG-64 test range and an indoor 48' far-field range covering 200 MHz to 44 GHz.

The company goes to market through a direct enterprise field sales motion — a consultative model accessed via business inquiry forms, phone (972-905-0437), and email — with no public pricing. Target verticals include container ports and maritime, airports and aviation, telecommunications (cellular and SONET timing), financial markets (GPS-derived transaction timing), power grids, connected and automated vehicles, and defense. Revenue is generated principally through hardware sales. The company is founder-funded with no disclosed institutional capital and is led by President Jeff Sanders, Chief Engineer Tom Tillotson (SIGINT and radio-location background), CFO Bill Broyles (CPA, CGMA), and a small team of senior DSP, RF, IT, and design engineers.

Core offering

UHU Technologies designs, manufactures, and sells hardware systems that detect and mitigate GPS spoofing and jamming attacks against critical infrastructure. Its two flagship GPS products — the Northstar GPS Health Monitor (detection) and the UHU1000 GPS Threat Mitigation System (detection plus active spatial nulling) — leverage patented angle-of-arrival spatial processing techniques borrowed from the Signals Intelligence (SIGINT) world, complemented by a line of purpose-built GPS and broadband antenna products.

Product overview

UHU Technologies offers a product portfolio centered on GPS spoofing detection and mitigation, comprising two primary GPS product lines and a complementary antenna product line. The Northstar GPS Health Monitor (detection product) and UHU1000 GPS Threat Mitigation System (detection and mitigation product) form the core offerings, with the Northstar focused on threat detection and alerting for civil infrastructure protection, and the UHU1000 providing active threat mitigation with spatial nulling capabilities for more demanding military and denied-environment applications. Both products leverage patented angle-of-arrival spatial processing techniques borrowed from Signals Intelligence (SIGINT). The antenna product line (UAN0101, UAN0201, UAN0202, UAN0204) provides purpose-built antenna solutions ranging from low-profile omnidirectional antennas for airborne datalinks to GPS L1/L2 band blade antennas, supporting the GPS products with dedicated multi-element antenna arrays.

Broad incumbents

• Spirent Communications: Spirent provides GNSS testing, simulation, and (via previous acquisitions) anti-spoofing tooling to defense and commercial buyers. Comparable as a GNSS testing/security platform but broader in scope than UHU's deployment-focused anti-spoofing hardware.
• Trimble Inc. Trimble supplies GNSS/GPS positioning across construction, agriculture, geospatial, and transportation. Some Trimble receiver lines incorporate anti-jam features overlapping with UHU's protected-GPS mission, particularly in transportation and ports.

Direct peers

• Hexagon / NovAtel: NovAtel (Hexagon) offers high-precision GNSS receivers with anti-jam and interference-mitigation features for aerospace, marine, ports, and survey. Overlap with UHU is strongest where maritime/port operators need GPS integrity, though NovAtel spans a much broader GNSS portfolio.
• Chronos Technology: Chronos Technology provides GPS jamming and spoofing detection systems (e.g., the "Sentinel" line) used in telecom and critical national infrastructure. Highly comparable in product positioning to UHU's Northstar for civil-infrastructure PNT integrity.
• BAE Systems (Electronic Systems, GPS Anti-Jam): BAE Systems produces military GPS anti-jam receivers and SAASM-based systems for nav-war. UHU's UHU1000 sits in the same threat-detection-and-mitigation category for denied environments, making BAE a direct competitor on military PNT programs.
• Raytheon (RTX) - GPS/Navigation Warfare: Raytheon's GPS and nav-war programs (e.g., NAVWAR payloads, anti-jam work) compete with UHU's UHU1000 in the military PNT protection space. Both address spoofing and jamming threats to platforms operating in denied environments.
• L3Harris Technologies: L3Harris delivers GPS anti-jam products (e.g., Navshield) and SAASM/M-code assured PNT solutions. Both companies operate in protected GPS for defense and critical infrastructure, with comparable angle-of-arrival-based jamming mitigation themes.
• Thales Group (PNT / GNSS Security): Thales develops GPS/GNSS anti-spoofing solutions and protected receivers. Thales competes directly with UHU's Northstar and UHU1000 for aviation and defense PNT integrity applications.
• Safran (Orolia) - PNT Timing: Safran acquired Orolia, which supplied GPS jamming/spoofing detection and resilient timing to financial, telecom, and power-grid customers — exact use cases UHU targets. Both address GPS-protected timing for critical infrastructure.

Emerging players

• u-blox: u-blox designs GNSS receivers and modules with emerging spoofing/jamming-detection features targeting automotive, industrial, and consumer segments. Partial overlap with UHU in autonomous-vehicle and connected-vehicle GPS integrity use cases.
