Will be very useful for “delivering supplies” to “lost hikers” in GPS-denied environment.


Yes, it's definitely important that lost hikers get what they need. Sometimes they get lost so much they end up in the wrong country!

I'm all for sending enough supplies to return them safely to where they belong.


  It's dangerous to go alone! Take this.


There’s a ycombinator startup doing this exact same thing for the DOD. Not much of a “moat” apparently.

Interesting... star trackers have been around since the 50s and inertial navigation / SLAM is pretty plug and play these days. Looks like the unique thing they are going after is spoofing GPS so that a consumer drone can fly in a GPS denied environ. Neat, but a bit dubious as an investment.


The problem with star trackers is that it's getting harder and harder to see the stars


It's messing with insects who use the stars and moon for navigation. Pretty wild. https://www.sciencedirect.com/science/article/pii/S096098222...


This is for killing people, right?


Just russian invaders


It is open-source so it can be used by both sides to kill each other, or to assassinate a well-protected political figure, or to inflict damage on a crowd.


so it uses computer vision to recognize objects like mountain, sea, land, buildings and figure out its relative position?

this is a pretty robust approach except when visibility allows it. wonder if lidar + CV would work better here rather than a pure CV approach

nonetheless its an interesting approach as in some jurisdictions you need a permit to operate a drone, something autonomous like this could work without involving bureaucracy


Lidar would reveal your drone existence and location to the, ummm, "park rangers" when you are “delivering supplies” to “lost hikers” in GPS-denied environment.


> wonder if lidar + CV would work better here rather than a pure CV approach

Not according to Tesla


As if bureaucracy doesn't care because it's autonomous.


LIDAR probably doesn't work over forests


if it's indoor, an IR blaster would be good enough.

lmfao permits are for law-abiding meat-bags; my swarm follows me autonomously, officer.
