That's why Israeli startup Sightec developed the first-ever artificial intelligence-powered drone that can navigate without GPS connectivity. The drone uses "its own judgment powered by computer vision and smart tech, to reach its destination and avoid crashes without human assistance," said Mashable.

The drones are embedded with special software called NaviSight, which transforms cameras embedded on the device into sensors that in real-time uses artificial intelligence to navigate like a human pilot, without depending on GPS. 

A recent test was conducted in Southern Israel using a drone with the startup's NaviSight technology. The drone successfully operated five routes.
