[edit] Summary

Note: GPS will not work the entire flight. Civillian GPS receivers built in the US have to stop working once certain criteria are met; namely, if you go too fast and too high at the same time. This is to stop the rest of the world creating GPS-guided ICBMs.

[edit] Features

• determine position
• determine velocity

• known reliability
• known accuracy
• known precision

• has to work reliably at altitudes up to 100km

[edit] Requirements

to be done.

[edit] Available Solutions

• GPS logging Arduino shield
• Nano GPS Logger
• NASA's The Navigator GPS Receiver

[edit] More info

• Apparently, usual commercial GPS recievers stop to work above a certain altitude for legal reasons. (cf. "Discussion of GPS modules on SparkFun forums")
• List of GPS receivers with higher than usual altitude cut-offs
• Accuracy, precision and reliability (keeping track of satellites) is not known for higher altitudes.
