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.

What is one of the main limitations of UAVs as mentioned in the video?

• They cannot fly in bad weather.

• They rely heavily on GPS for navigation.

• They are too large to navigate easily.

• They are too expensive to produce.

What is the primary focus of the research at Brigham Young University?

• Reducing the cost of UAV production.

• Improving the speed of UAVs.

• Creating UAVs that can operate without GPS.

• Developing larger UAVs for cargo transport.

Which devices are used by the new UAVs to navigate without GPS?

• Radar and sonar systems.

• Cameras and depth sensors.

• Satellite communication systems.

• Infrared sensors and lasers.

How does relative navigation help UAVs?

• It reduces their energy consumption.

• It increases their payload capacity.

• It helps them avoid obstacles by using local surroundings.

• It allows them to fly faster.

What was the error margin during the UAV's test flight using relative navigation?

• Less than 10% of the distance traveled.

• Less than 5% of the distance traveled.

• Less than 3% of the distance traveled.

• Less than 1% of the distance traveled.
