The APRS Global Internet System
The Automatic Packet Reporting System
(APRS) is a global two-way tactical digital communications system that
allows amateur radio operators to transmit weather data, telemetry,
text messages, and plot their location on a map when no Internet or
Cellular coverage is available. APRS supports callsign to
callsign email, messaging, bulletins, and voice communications.
APRS enables any amateur radio operator to contact any other amateur
radio operator anywhere in the world at anytime. Learn more about
the APRS system at www.aprs.org.
A vehicle equipped with a GPS receiver, a VHF or HF transceiver, and a
small device called a transponder transmits it's location, speed and
course in a small data packet, which is then received by a nearby iGate
receiving station which then forwards the packet to the Internet.
Systems connected to the Internet can send information on the APRS-IS
without a radio transmitter, or collect and display information
transmitted anywhere in the world. |
