I carry a “Spot” satellite transponder that is capable of broadcasting a position from most parts of the world. When underway, I try to send a position once per day or so. Here are a couple of different maps where you should be able to view my most recent positions.
If I have sent a position within the last 7 days, it will be visible on the first map below. (To see full-screen, click here.)
This other map should show older positions as well. (To see full-screen, click here.)
