Independent radio monitoring, software and research based on publicly observable transmissions.
Live tar1090 instance fed from position reports received over ACARS, VHF Data Link Mode 2, and HF Data Link (HFDL). There is no ADS-B data here (!). This map is fed purely from textual position reports such as ADS-C, AGFSR, POSRPT, OBS, POS02, H1 ACMS R-lines, XID, POS01/02/03, and generic POSN.../POSS reports, extracted and parsed.
A continuous stream of the latest VHF ACARS, VDL Mode 2, and HF Data Link (HFDL) messages received. There's mild enrichment for type and military status. The searchable corpus is limited to the last seven (7) days. Regex searches are supported using /pattern/ syntax for all your exotic filtering needs. New to regular expressions? See the Regular Expressions Quick Start.
