Secure Operations

Luna-S is incorporated with hardware and software failsafe redundancies to ensure very high safety operations.
sort
Mechanically designed with a high factor of safety, the chassis is able to withstand more than 3 times the desired load.
sort
The autopilot features a number of failsafe procedures. If the battery drops below a warning threshold, Luna-S will return to the launch site. If the battery drops below the critical level, Luna-S will land immediately.
sort
Luna-S will not engage in the case of insufficient GPS satellites, unhealthy sensors, inaccurate flight path inputs, and many more conditions to prevent any unexpected errors, ensuring a safe and secure operation.

More Work is Done

Luna-S has a significant advantage when it comes to the industrial applications. With more flight time, it is now possible to get more work done, and get more results per flight. Achieve greater lengths with the high endurance.
sort
It takes around 30 minutes to inspect an electric pole. Other drones can only work for about 15 minutes, so a battery swap is necessary to finish inspecting an electric pole. Luna-S on the other hand, can finish inspecting a complete electric pole and still have plenty of power left, without the need to change battery, saving you time and effort.

While conventional drones can go as far as 3 km away to inspect a disaster zone, Luna-S can go at least 3 times further, giving you an edge of reaching the disaster zone faster.
sort
Luna-S can achieve up to 4 times more mapping coverage compared to the conventional drone, with the higher flight speed and longer flight time. Maximize your efficiency by completing the job with less effort.
