# APRS
(Automatic Position Reporting System)

[UI-View and APRS] This should be read after reading the section on the Packet Radio Data Systems operation. A newly developed form of amateur packet data, enables perhaps someone traveling in a vehicle in Ontario to chat with someone in Bristol via the keyboard. Obviously those doing the typing,would have to be the passengers. Each party able to see on a computer screen map exactly where the other party is, and zoom in to see them actually traveling along a street in real time. UI-View (Written by Roger G4IDE) is the UK version of APRS (Automatic Packet Reporting System). It operates and is a derivative of Packet Radio, using the very same equipment, but is entirely separate from that system. Ui-view is the very latest development in packet radio, and is stillunder going rapid development. The system again, forms itself into a network, but this time amongst those on-the-air at any instant, in a peer to peer radio network. You turn your system on, and it instantly becomes part ofthat network. A map (local through to world wide) shows the locations of amateurs presently using the system, be they at home, mobile perhaps in their car or on a boat etc.. It is perfectly possible from theUK, to see a mobile station perhaps in Australia, and enter into a keyboard to keyboard chat with them, as well as be able to zoom in on the map (if you have an Internet connection), to the pointwhere you can see the street in the Australian city where the other amateur is located. During the games in Australia, one amateur was at the games with a small APRS capable hand-held tranceiver, and able to keyboard chat to others around the world.
