Sure but I'd spend the money on something like a self contained GPS tracker so one doesn't have to pay monthly fees for something they only use a short period of time out of the year. Need to have cell service where one is flying in order for this stuff to work. Best to pay <$200.00 for a self contained GPS rocket
tracker then this stuff. Kurt
These have been around for awhile. Basically they're like those little cellular GPS location messengers except that they use the satellite phone network to send out text messages instead of using the cellular network. They might be useful out at places like Black Rock, but at $150 per year + another $50 per year if you want the tracking to go on for more than 24 hours it could be an expensive alternative, particularly since you have to shell out that much for every device that you purchase.
The Spot Trace for $50 could work if you have a clear shot at the sky to get a good GPS fix and can reach the Spot satellites. The disadvantage is the $150 per year per device subscription cost. It appears is would only be useful in a 4+" diameter rockest and the rocket could not be carbon fiber.....
Take the $150.00 and apply it towards an EggFinder and LCD receiver. Will have a portable system with no subscription charges. The Android program GPS Rocket Locator has just come out with portable map tiles option. Download a map and carry it
to a launch site on your device. No internet required. Kurt
