It would be interesting if he could add GPS to Signal[1] boards. GPS would obviously provide lat/long, but also altitude.

Can we not turn hacker news into Reddit.
Sadly, it's a bit too late for that.
I'm just thankful on this Thanksgiving day as I try to live here in the USA that my HN social score (Karma I think they call it here, funny, sounds like reddit) is not yet used to limit my boarding of high-speed rail or getting a loan or even a mortgage.

#24https://bps.space/ has some additional details, including the flight computer that does thrust vectoring (on a model rocket!). This makes me want to build model rockets again..

If you need FOSS app for design & simulate model rockets -- use OpenRocket.[0,1,2]
There are many tutorials on YouTube.[3,4,5,6,7]

#25Someone once told me you're not supposed to make rockets with guidance control (in the US) because they are then missiles. Is that true? Is this guy in the US?
His flight systems are all attitude control, not guidance to a target. It’s a silly distinction but apparently makes things OK. He’s talked with state dept people a lot to be able to sell his kits internationally.

I'm not sure how thrust vectoring is altitude control... I suppose it's OK to steer then so long as your "target" is the general direction up. I can see value in that.

attitude control, not altitude control. Thrust vectoring controls the attitude of the rocket. As in where the nose is pointing.

He's measuring altitude with the onboard Barometer. Adding GPS to this board would make it highly problematic from a legal standpoint.
