Jamming communications doesn't make robots useless. It just means that they can't be controlled remotely, can't use GPS to navigate and can't provide real-time surveillance.

That can be worked around by pre-programming a fixed route or an objective to be fulfilled autonomously, by using celestial navigation or geographical landmarks, and by having surveillance drones return to base to deliver recordings using a physical connection.

Honestly a swarm of drones with laser based communication sounds just like the thing that may make widescale jamming useless in the future. Also, makes jamming pretty risky since something will head your way... and explode.

Are there drones that use celestial navigation?

What if it's cloudy?

I don't know about drones, but it is in use for missiles https://en.wikipedia.org/wiki/Missile_guidance#Astro-inertia...

Cloudiness would be a problem, but in that case you could still fall back to a combination of other systems.
