Elsight adds cellular-based positioning to its Halo unit

Elsight, which trades on the ASX as ELS, aims the capability at air, land and maritime platforms. A patented method derives position from cellular measurements, so navigation continues where satellite signals are lost or untrustworthy.

A fusion engine layers more data onto that fix: Timing Advance values, nearby base-station signals, motion and velocity vectors, and GPS whenever it checks out as reliable. The company says the engine adapts as inputs come and go and works on any available network regardless of its owner. GPS remains the default source; cellular takes over only when GPS drops out.

Spoofing detection runs in parallel. It compares the GPS position with the cellular-derived one in real time and alerts the operator when the two diverge beyond a threshold. Elsight claims no other GNSS-denied positioning offer rests on patented multi-signal fusion, and calls this the first with built-in active spoofing detection.

CEO Yoav Amitai calls GPS a critical weakness in contested environments. Other approaches, he says, report how far a platform has travelled, while Elsight’s reports where it is. The company states that the function needs no GPS, internet, visual reference or communications link.

Existing Halo customers need no extra hardware. Elsight pitches the feature as a small, light and affordable alternative to heavy or costly navigation equipment.

Why it matters

Specialist units alone once held jamming and spoofing equipment, while regular forces now field it broadly, and the growing use of uncrewed systems puts electronic warfare at the centre of tactical planning. A platform that cannot trust its satellite fix risks losing navigation and its mission.

Halo is the base for the new function. It combines cellular, satellite and RF links into a single connectivity layer that picks the best path and supports operations beyond visual line of sight without ground infrastructure. Elsight cites more than 500,000 operating hours with over 100 active customers, and Halo is on the DCMA Blue List. Fielded fleets can gain the new capability by software update rather than retrofit.
