Onboard gps units tend to drop out at high altitude and/or high velocities due to COCOM limits. Some will re-acquire at apogee but it doesn't always work. I'm planning for onboard telemetry but a multilateration system is the backup.
I correspond with others on aRocket and unrestricted gps units still aren't available to the average person without a lot of paperwork and $$$. -Bob On Jun 6, 2012, at 22:13, Chris Albertson <[email protected]> wrote: > Why not fly a tiny GPS inside the rocket?
