Unlimited Flight Time: The G70-M400 Tethered Power Station for Persistent Surveillance
Every battery-powered UAV eventually lands. For security, inspection, and event-monitoring missions, that forced landing is the single biggest operational constraint — it creates coverage gaps, requires backup aircraft, and drives up the cost of continuous observation. Tethered power removes the constraint entirely by feeding the aircraft from the ground, turning a drone from a 30-minute tool into a persistent aerial sensor that stays aloft as long as the mission requires.
The G70-M400 Tethered Power Station is built for exactly this use case: industrial operators who need an eye in the sky that does not come down.
How tethered power changes the mission profile
A tethered system replaces the onboard battery with a thin cable that carries high-voltage DC power from a ground station to the aircraft. The aircraft still flies normally, but its endurance is now measured in hours instead of minutes, and it is limited only by the length of the tether and the reliability of the ground power source — which for most installations is a generator, mains power, or a vehicle supply.
This has profound implications for how operators design their surveillance and inspection programs. Instead of rotating three or four aircraft to maintain continuous coverage, a single tethered unit can hold station over a perimeter, a crowd, or a critical asset indefinitely. The G70-M400 provides the ground-side power conversion and management needed to sustain that kind of operation safely.
Where persistent flight pays for itself
Border and perimeter security is the most obvious fit. A tethered UAV hovering above a fence line or entry point gives operators a persistent, elevated vantage point that fixed cameras cannot match, with the ability to slew to a moving target on demand. Because the aircraft never has to land to swap batteries, the security team gets true 24-hour coverage from a single platform.
Event and traffic monitoring is another strong case. Large public gatherings, construction closures, and disaster-response staging areas all need sustained aerial observation, and the overhead of battery rotation is exactly what operators want to eliminate during a time-sensitive operation. A tethered system lets the command post keep one aircraft up for the entire incident, with the video feed routed down the tether alongside the power.
Industrial inspection benefits too. For long-duration monitoring of a flare stack, a bridge repair, or a slow-moving construction sequence, the ability to hold a camera in a fixed position for hours removes the scheduling complexity of repeated flights and gives engineers a continuous record instead of a series of snapshots.
Integrating a tethered station into your fleet
A tethered power station is a complement, not a replacement, for conventional battery operation. The smart play is to keep your free-flying aircraft for mobile missions — mapping, patrol, delivery — and reserve the G70-M400 for the fixed-point, long-dwell missions where endurance is the entire value proposition. Together they cover both halves of the industrial UAV workload: reach and persistence.
For security integrators, event operators, and inspection providers, persistent flight is the capability that separates a drone service from a real surveillance system. The G70-M400 delivers that capability from the ground up.
