Question T8D03
From subelement T8 - T8D
What kind of data can be transmitted by APRS?
Why is this correct?
APRS (Automatic Packet Reporting System) can transmit all three data types listed. GPS position data is APRS's primary function for tracking mobile stations. Text messages allow short communications between operators. Weather data enables stations to share meteorological information. Since APRS is a versatile digital packet system designed for multiple data types, all choices are correct.
Memory tip
When you see 'All these choices are correct' answers, verify each option individually rather than looking for the 'best' single answer. APRS questions often test multiple capabilities because it's a multi-purpose system combining positioning, messaging, and data sharing functions.

APRS serves as amateur radio's digital Swiss Army knife, integrating three core functions that support emergency communications and routine operations. The system's packet radio foundation enables reliable data transmission using error detection protocols. In practical deployment, APRS networks create situational awareness by combining real-time position reports with weather telemetry and tactical messaging—essential capabilities for emergency response coordination and mobile operations where voice communications might be impractical or insufficient.
Think about it
Why do you think APRS combines positioning, weather, and messaging capabilities rather than specializing in just one type of data transmission?
