I would look for a device that uses the Globalstar
network. The SPOT would work
but it requires the person on the boat
to interact with the transceiver for it to work
. My guess is you are looking for something that transmits the boats position automatically on a frequent and consistent basis.
I found a couple Globalstar
based services by doing a Google
search. I have not used either so I cannot vouch for them.
AeroAstro - Asset Tracking and Remote Monitoring Solutions
Worldwide GPS Satellite Tracker SX1
Globalstar - Wikipedia, the free encyclopedia
I'm curious, as well as others I would imagine. Would it be okay to ask for a few details about how you plan on using the tracker?
