How does aprs work?
- APRS uses AFSK (Audio Frequency Shift Keying) to transmit data packets.
- Data packets carry binary data containing position data, messages, etc.
- Any VHF or HF transceiver with a TNC and a data source (GPS, computer, etc) can transmit an APRS packet.
- APRS packets can be handled in one of two ways:
- Repeated (“digipeated”) like a typical FM voice repeater
- Sent to the internet through iGates.
