Underground railway networks that run like clockwork require routine inspection to prevent service disruptions. Checks by foot or  inspection machinery on rails are just too costly and heavy.

We believe that railway inspections should be efficient, safe and powerful at the same time. Our customisable platform allows just for that, so that your services can run seamlessly.

Deep tunnel water systems are almost impossible to effectively survey or inspect due to constant liquid flow, inaccessibility and hazards.

Where remote rovers and boats get stuck, our BL-108 flies on. Engineered to fly in and survey humid and moist environments, you can be sure that you will get the results you need.

Aging underground power lines and cables have uneven surfaces and non-linear surfaces which limit the usage of remote ground vehicles.

Our BL-108 platform is able to speedily survey and inspect the full length of power transmission tunnels. and with EMI shielding, you can be sure that no interferences are sustained nor caused.

Our service and product competency is not just limited to underground tunnels. Confined spaces like roads that are above ground also face surveying and inspection limitations. 

ALT's expertise ensures that be it underground or overground tunnels, we can develop a solution for you.

 

AUTONOMOUS GPS-LESS NAVIGATION MADE POSSIBLE BY OUR VERY OWN UAV PLATFORMS

A FIRST OF ITS KIND

A fusion of both Stereo Camera and LIDAR sensors provide unmatched obstacle avoidance capabilities while having navigational redundancies in place should things go south. Our flight algorithms are also optimised for low-light moisture heavy environments.

While the Stereo camera enables forward flight into tunnels, the LIDAR sensor allows the aircraft to steer clear of obstacles and walls. In the event of blocked camera vision, the LIDAR acts as a contingency navigation sensor.

 

ALL SEEING EYE

Mounted on the front of the aircraft is a 4K 360 degree camera providing seamless high-definition footage of the tunnel ceiling, sides and floor simultaneously.  

 

The versatile payload mounting points on the BL - 108 mean that you are not limited to visual footage. Remote sensing equipment like thermal and multispectral cameras can be easily affixed upon the platform to shed greater insight to infrastructures.
