BRATS APRS Digipeater: W3GXT-2 144.390

The BRATS W3GXT-2 APRS Digipeater is a Wide digi that supports APRS activity in the Baltimore metropolian area. APRS (Automatic Position Reporting System) was developed by Bob Bruninga (WB4APR). APRS generates a computer map display which shows the position and speed of any type of vehicle, shows weather stations transmitting real-time weather data, facilitates real-time emergency communications, tracks space craft and has many other uses. APRS uses a "broadcast" of packets that are normally not addressed to any one particular station. Thus APRS is more efficient than conventional packet at distributing information to a large number of stations. APRS local traffic can be "gated" onto the internet or onto the HF APRS frequency and received around the world. Users can send messagse through the internet to a regular email address or to another station that is normally out of range. There are several types of APRS client software available that run on desktop computers, laptops and PDAs using DOS, Windows, Linux, and other operating systems. APRS is an integral part of BRATS's support of public service activities.
