St. George Island Aircraft Communications
Live ACARS message feed and aircraft datalink monitoring
ACARS (Aircraft Communications Addressing and Reporting System) is a digital datalink system used by aircraft to transmit and receive short messages between aircraft and ground stations via radio or satellite. Think of it as "text messaging for airplanes."
These messages are automatically sent throughout a flight and contain valuable information about the aircraft's status, position, and operations. ACARS has been in use since the 1970s and is a critical component of modern aviation.
Flight positions, weather reports, engine performance, departure/arrival notifications, maintenance alerts, and operational updates.
Aircraft transmit messages via VHF radio frequencies (131.550 MHz, 131.725 MHz, 131.825 MHz in North America) or satellite links.
ACARS monitoring helps track flights in real-time, especially in remote areas like the Pribilof Islands where radar coverage may be limited.
Local Monitoring: This ACARS feed is captured by a ground station on St. George Island (PAPB), allowing us to monitor aircraft communications in the Bering Sea region in real-time.

Updates: ACARS messages appear in real-time as aircraft transmit them. Activity varies by time of day and flight schedules. Messages are displayed in chronological order with the newest at the top.
