What is APRS? APRS - Automatic Position Reporting System. Frequency: 144.390 MHz, 10.151 MHz LSB Automatic Position Reporting System originally developed by Bob Brunigar,WB4APR. APRS is trademarked by Bob Brunigar,WB4APR. MacAPRS and WinAPRS is trademarked by Mark,KB2ICI and Keith,WU2Z Sproul. APRS combines the use of Amateur Radio packet systems, Global Positioning Satellites (GPS), Weather stations, and the Internet to make use of real time physical location and weather information. APRS information can be obtained through the Internet, via a receiver or scanner, or to transmit your information a transmitter is required. APRS Software is available for DOS, Windows, MAC, Linux, Java, Perl, Windows CE devices, and the Palm Pilot. Using your current packet program you can receive the packets from the APRS system, you will not have the maps etc, but you can see the callsign, latitude, longitude, position reports, messages, etc. The basic equipment to use APRS on air is a computer , TNC, and a radio (scanner, receiver, or transceiver). There are many Internet sites that have live feeds from the APRS system so that you can see what is going on in the world without having to use a radio/TNC combination. What can APRS be used for? An APRS system can be utilized in many ways, from tracking a mobile station, sending messages to each other, radio direction finding, seeing if satellites are within your receive footprint, CANWARN and storm warnings, tracking weather statistics, and using this information for weather prediction/analysis, moving map general purpose navigation. One of the uses proposed is during emergency communications to keep track of the stations that you have deployed for communications. You can create objects on the display that is sent out via APRS, ie you can mark on your APRS map a station location, even if that station itself is not set up for APRS - great for event communication coordination and control. You can use APRS for general navigation HOWEVER, be aware, depending on how the maps were created and accuracy of those maps and data, your position can be off. Case in point, one of our local Amateurs entered his Lat Long using a topographical map and GPS coordinates, and when plotted on some maps within APRS placed his house on the wrong side of a major highway, on the wrong side of a river and even out in Lake Ontario!! - watch out for that sand bar! Seriously though, it is accurate enough for most needs. GPS units are now very accurate themselves since the United States turned off Selective Addressing at 12:04 am EDT 2 May 2000. (SA - used to add a random error to the plotted position). If you are running a mobile APRS station, with or without a radio, under WinAPRS, you can have the map scroll, as you travel, great for your right seat/back seat Navigator(s) when you're taking those scenic trips!! WinAPRS now supports the Baycom modem and sound card use through the use of SV2AGW's AGWPE.
