|SPOT on APRS|
|Written by Peter - VK2US|
I guess you followed a link here from an APRS message that you saw that got you a little curious. Well OK here's a brief overview of what we've done, and I guess why.
Firstly what is a spot? Well in it's simplest form it is a personal tracker. This is a small handheld, or belt worn, device that will acquire it's position from a built in GPS satellite receiver and relay this on command back via the Globalstar network. It can also provide an automated position fix every 10 minutes as well as having assistance and emergency messages available. To have a look at these things try the spot webpage.
OK, so what is APRS? Well just in case you didn't know it's a system we amateurs have that allows us to broadcast our position via radio so that other amateurs, well anyone that cares to look, can see as. As well as this the system also contanis messaging and broadcast functionality.
Now as can be seen from the above we have to systems that are involved in the reporting and display of positions so it seems natural that the two should get together. From an amateur's perspective here are a couple of reasons why we did this:
Operation is fairly straight forward and occurs in 2 steps.
We collect the data from the SPOT servers.
We submit it to the APRS network under the users callsign.
This system is still in the development stage however is showing a lot of promise. If you're an amateur, even a foundation call, and have a spot feel free to contact me with your email address and callsign and we'll add you to the list of units we're watching. If you'd like a little more information on this feel free to have a look at the about page and FAQs or if you've just arrived here then feel free to look at the rest of our site.
Regards & 73's
