So there's a project I'm currently working on and don't have a lot of experience about.
We are basically building an autonomous boat that will go through the Atlantic Ocean alone.
I'm in the software dev team and I'm just getting together ideas on how to navigate and send signlas back to us.
So what I need ideas for is:
How to navigate the boat from point A to point B through the Atlantic Ocean (GPS or alternatives?)...
How could we send a signal from the boat every now and then when the boat is in the middle of the ocean just to know wether it's still out there or if it sunk?
Any ideas would be highly appreciated, I just need to be pointed in the right direction.
That's a side dedicated to exactly this kind of stuff.
There are previous entries described and they list their navigation, communication and control devices.
GPS/GLONASS yes, no other radio signal you can pick up once away from shorelines. Or go with more complex sun/star sighting equipment & IMU/ded reckoning computations.
Satellite data communication back to land. Maybe get a cheap datarate from Iridium or someone like that.

That's exactly what we are participating in. I managed to get a lot of info from their site already, just getting more and more ideas.

We'll be probably be using GPS and a compas for autopilot and RockBLOCK Mk2 / RockBLOCK+ or SPOT Track. I'm thinking that SPOT Track is currently the best product and it's also the cheapest.
We will see... Keep the ideas coming please, thank you.
The floor of the Atlantic ocean has lots of lumps and bumps.
With a high power (expensive) sonar system you could estimate your location based on the topography.
