Integrated asset intelligence for next-generation transmission systems.
SAMSTEO began life as SAMST — Smart Audit & Monitoring System for Transmission Towers — a LoRaWAN sensor network built to make high-voltage towers report their own condition. It became SAMSTEO when we added the orbital layer: Earth Observation data that extends monitoring from the towers we have instrumented to the entire corridor around them.
Preventive maintenance on transmission infrastructure still depends largely on human inspection: a crew, a vehicle, a schedule, and terrain that makes both expensive. Between two inspections, an asset is unobserved. Everything that matters — a loosening joint, a tilting foundation, vegetation closing on a conductor, a thermal load the design never anticipated — happens in that gap.
Sensor nodes report structural and environmental telemetry from the tower itself: inclination and tilt, vibration signatures, electromagnetic field readings, temperature, humidity and barometric pressure. Readings arrive continuously rather than annually, which is what makes a baseline — and therefore an anomaly — meaningful.
Transmission corridors run exactly where cellular coverage does not. LoRaWAN gives kilometre-scale range at milliwatt power budgets, so a node survives on battery in a location with no mains supply and no signal — and keeps reporting during the cellular outages that tend to accompany the events you most want visibility into.
Instrumenting every tower on a national network is neither affordable nor necessary. Satellite imagery covers the corridor between instrumented towers: vegetation growth against clearance envelopes, ground movement, burn scars and post-event damage assessment. The sensors give depth at points; EO gives breadth across the line.
Raw telemetry is not an operating decision. SAMSTEO establishes a per-asset baseline, detects departures from it, weights them against forecast conditions, and surfaces a ranked view of which assets warrant attention first — so a maintenance budget can be spent on the towers most likely to fail rather than the ones next on the rota.
We will walk you through a live deployment and what a pilot on one of your line sections would involve.
