When we conduct drone inspection work, precision and accuracy are always of critical importance.

Whether it is the thermal detailing or the high quality photography of visual inspection work. But it is all conducted with some of the most advanced GNSS and GLONASS systems available. These systems are vital for both safety and precision inspection work.

Our drones can all fly with two modes. GNSS and Non Satellite Modes. GNSS is the abbreviated name for Global Navigational Satellite Systems, a version of which is best known as GPS. Highly accurate drone navigation is incredibly important when we are conducting our inspection work, especially in 3D modelling and surveying work.

setting up a drone for an initial building inspection

While our indoor and confined spaces drones will often fly in non satellite mode due to the signal limiting factors of built up structures, the majority of our aerial drone work is conducted with GNSS GPS. It all begins with a link up to GNSS satellites and Satellite Constellation Technology. This is where a group of satellites work together in order to generate coordinated coverage. This coverage is the period in which a satellite is visible above the horizon. When we ‘power up’ our drones to begin an inspection flight, this is the first procedure that the drones will activate before flight can begin.

This GPS information can be used to then display the current position and location of our drones in relation to our drone pilot and allows us to set a specific ‘Return to Home’ location that is a primary safety feature of inspection drones.

Return Home Systems

There are three safety systems that will activate a ‘Return to Home’ response from the drone.

1 – Drone Pilot Activation Button. We can activate a ‘Return to Home’ setting from our drone pilots controls.

2 – Low battery safety setting. If the drone has hit a low battery warning level, it will automatically ‘Return to Home’

3 – Signal loss. If the drone looses communication with the drone pilot, it will begin an automatic ‘Return to Home’ safety procedure.

Why does Radar Positioning matter for drone inspection?

Being able to plot GPS coordinates for drone inspection work in vital both for the ‘Return to Home’ systems mentioned above but also for conducting a variety of live inspection and modelling services and future overlay inspection work. By marking set GPS points, we can conduct exact replica inspection work in the future. Taking images and video of the same points of interest from the same location, height and angles. This can be an invaluable tool in the monitoring of ‘points of interest’ on building structures, bridges, oil platforms and so much more.
