New breed of drones can navigate without GPS!

The video discusses the potential of unmanned aerial vehicles (UAVs) beyond their current GPS dependency. It highlights the challenges UAVs face when GPS signals are weak or blocked, such as in urban environments. Researchers at Brigham Young University, funded by NSF, are developing UAVs that use onboard sensors and algorithms to navigate without GPS. This relative navigation system allows UAVs to estimate their position and velocity using local surroundings, improving their reliability and safety. The video concludes with successful testing results and the promise of further advancements in UAV technology.
