Elsight Launches GPS-Denied Drone Positioning Technology

Elsight Introduces Positioning Tech to Keep Drones Navigating Without GPS

Elsight, a Texas-based connectivity company, has introduced a new positioning capability designed to help uncrewed systems determine their location even when GPS is unavailable, jammed, or spoofed. The system uses cellular network signals as an alternative source of location data, targeting autonomous platforms operating across air, land, and maritime environments. It is integrated into Elsight's Halo platform, which combines cellular, satellite, and radio-frequency links to maintain connectivity for uncrewed systems. Existing Halo customers can access the new feature through software or a feature unlock, without installing additional hardware.

Key Facts About the New Positioning Capability

• Alternative location source: cellular network signals, including Timing Advance measurements and nearby base station signals.
• Multi-source fusion engine: combines cellular data, verified GPS, and motion and velocity information.
• Built-in GPS spoofing detection: compares GPS-derived coordinates with independently calculated cellular position in real time and raises an alert when they diverge beyond a threshold.
• Absolute geographic positioning: reports actual location rather than only movement relative to a starting point.
• Claimed operation: without GPS, internet access, visual references, or an active communications link.

What This Means for B2B Drone Operators and Suppliers

This means GPS-denied operation demands more onboard compute, sensor fusion, and power, especially continuous supply and thermal management. For battery providers, these high-reliability drones need wide-temperature, vibration-resistant, long-endurance packs, and possibly redundant power architectures. Defense, security, and industrial inspection operators should note that cellular positioning depends on the availability and quality of usable network signals, and accuracy can vary by environment. It is not a universal replacement for GPS or a guarantee of uninterrupted positioning everywhere. Still, the approach addresses a real challenge: as drones take on more demanding missions, reliable navigation increasingly needs a backup plan when satellite signals cannot be trusted.

Market Context and Source

GPS jamming and spoofing have become growing concerns in military operations, with electronic warfare tools increasingly used to disrupt navigation and communications. For drones and other autonomous vehicles, losing reliable positioning can complicate everything from route planning to mission execution. By using cellular infrastructure as an independent reference and checking GPS against it, Elsight aims to add resilience without significantly increasing platform complexity.
