Yes, coverage is great in metro areas of larger cities. It gets a bit spotty in mountainous areas of the Western US. For Example, my buddy AL in LA today. If I put the APRS unit in my car, and drove from Utah to Los Angeles, there might be some gaps in coverage along I15. You can go to the APRS.FI site, put in a geographic location, and search for all APRS stations close to that. That will give you an idea of the coverage in your area.What kind of coverage area does the APRS network have in the US? For instance, if I wanted to make a tracking unit for my car, and it was stolen, I would want to be able to see it's location even if it had been loaded up on a flatbed and taken across the country. Would the APRS network allow this?
No, a small donation to aprs.fi or other web host would be appreciated.Is there any kind of charge for using this network?
This one is available in kit from, and is based on a PICDo they make modules that operate at this frequency that can just be controlled by a uC that are similar in size to a RF IC or a GSM module?
You need a micro controller, GPS receiver, GSM module, and a SIM card.
You parse the incoming data from the GPS in the microcontroller. At whichever interval you program, you then have the microcontroller send data via AT+ commands to the GSM module to dial a number and send a formatted text message. You can give the location via internet, but I believe this to be a good bit more difficult than sending a text message.
As Nigel said -- it is not "easy" or "simple."
