Three UAVs are flown autonomously by computer in tight formation without aid from any Global Navigation Satellite Systems (GPS, GLONASS, Beidou, Galileo etc).
Video Synopsis:
Current outdoor UAVs utilise GPS or GNSS signals for navigation outdoors. However, GNSS signals are inaccurate (up to 5m accuracy) and are susceptible to interference or jamming. GNSS signals also perform badly in vicinity of tall buildings or structures due to poor satellite signals needed for positioning. GPS RTK signals, although more accurate than GPS, are also susceptible to interference and blocked signals from tall structures in the vicinity.
We aim to overcome the above problems by circumventing the use of GPS(GNSS) and to provide precise outdoor UAV applications in a GNSS-denied environment and this is a simple demonstration of our result from many months of R&D. Three UAVs are shown flying right next to a tall building and trees with precision and positioning accuracy.
Potential Commercial Applications include:
Urban UAV transport/delivery, UAV security surveillance in a dense urban environment. UAV applications in GPS denied environment such as forested areas and indoors, and any outdoor UAV applications near tall structures such as buildings, trees, power cables or electricity pylons.
