"How about very loose strings then, rather than tight rubber rings? That would surely decouple the vibrations, right? ;)"
"Hahaha, this is so interesting. So different to the dynamics I am used to.
So you do want to introduce lag then, on purpose, because you are more worried about high frequency vibration, yet you are not worried about what the lag will do to the…"

"Well, this will introduce phase lag for sure. It's possible that if the rubbers are very tense, and given that the autopilots are very light, it works out in the end. Back in the day working on these guys…"
"That's got to be terrible for dynamics."
"Damn right, as others point out, high precision outdoor navigation is definitely within the realm of current sensors. DGPS for one, down to +- 1 cm. Getting it below that should be an interesting nav problem but definitely doable.

"That's crazy. GPS is primarily a military system. Legislation *will be changed* if this affects GPS reliability."
"Hey! You guys were across the street from Masten Space Systems, winners of the Lunar Lander Challenge and builders of the rocket equivalent of an ArduCopter (ArduLander?). If I had known I could have gotten you a tour."
Hello all,Anybody here has experience with trying to remove the export-control velocity and altitude limits from any of the popular GPS receivers? I am thinking U-blox, Mediatek or SiRF. I know these limits can be removed from the high-end units…
