VLF transmitter

[nitro]

I want to deploy my own buoy to sea. I want it to transmit it's position to me as well as other telemetry. I think the only way to do this is with a VLF transmitter.

Does anyone know of something small and low powered that can do this?

I believe NOAAs buoys are tracked by satellite via radio signal/phone. I can't imagine their transmitters are low-powered.

How are you going to receive your signals? Hack into a satellite? Or are you going to have a receiver nearby all the time?

Here's some reading material:

Have you looked into amateur (Ham) radio equipment? They have 160 meter and 80 meter bands which may be of interest.

I have no idea about pricing but I'm sure it's not cheap, both to purchase outright and the recurring fees. But this might do it.

Digital email to an amateur satellite for re-transmission,
when it's overhead, and you request your email from it.
VHF/UHF bands, solar/wind/wave power.
