Indoor drone shows
What is an indoor drone light show? How does it work? Our experts answer!
Indoor drone shows open up new artistic possibilities. These shows are increasingly popular with theme parks, theaters and exhibitions. How do they work indoors and without GPS? Let's discover the secrets of this innovation...
What is an indoor lighted drone show?
An indoor drone show is a synchronized performance of illuminated drones, performed in an enclosed space such as a concert hall, indoor stadium, auditorium, convention center or theater, for example. Unlike outdoor shows, which use the sky as a backdrop, these shows exploit indoor environments to create immersive visual effects that complement stage sets and other performing arts such as mapping.
This type of show is attracting increasing interest from many sectors, including theme parks, theaters, exhibitions and concert halls. The absence of weather-related constraints and the possibility of total control over the lighting environment make this a very popular option.
How do indoor drone shows work without GPS?
Unlike outdoor drone shows, which use GNSS RTK (a precise satellite navigation system), indoor shows have to do without GPS, whose signals don't pass through confined spaces. To overcome this, several positioning technologies have been developed.
One system is based on optical analysis. Drones are equipped with cameras and sensors to scan their environment in real time. They use visual markers placed on the ground or on walls to orient themselves precisely and adjust their trajectory without colliding.
Another effective solution for guiding drones indoors is Ultra-Wideband (UWB). This system recreates a sort of artificial GPS constellation inside the venue.
UWB beacons are strategically placed in space, like GPS satellites in space. They emit signals which the drones pick up to determine their exact position. This technology delivers impressive precision, essential for synchronizing drone movements without risk of collision.
Before the performance, the show is meticulously planned using 3D modeling software. This design phase orchestrates the drones' trajectories and ensures their perfect synchronization in time and space.
