Team, Got a few lines of data from dump978 and would like to have someone explain. Using RTL dongle no special antenna (vertical). My QTH is central Texas - one packet is deep S. America and the other is Mid-Alantic ocean. This is exactly as I received it, no edits other than it's cut out of the data stream: HDR: MDB Type: 1 Address: AE7825 (Vehicle address) SV: NIC: 13 Latitude: +45.1019 Longitude: -38.9355 Altitude: 6500 ft (geometric) Speed: 164 kt Dimensions: 55.0m L x 33.0m W (position offset applied) UTC coupling: yes TIS-B site ID: 0 MS: Emitter category: Space / transatmospheric Callsign: squawk ..01QFK4 Emergency status: No emergency UAT version: 1 SIL: 0 Transmit MSO: 0 NACp: 10 NACv: 4 NICbaro: 0 Capabilities: CDTI Active modes: Target track type: true heading AUXSV: Sec. altitude: 57675 ft (barometric) HDR: MDB Type: 16 Address: 648320 (reserved (national use)) HDR: MDB Type: 8 Address: 8510C9 (reserved (national use)) SV: NIC: 8 Latitude: -21.8338 Longitude: -63.2043 Altitude: 100350 ft (geometric) N/S velocity: 133 kt E/W velocity: -8 kt Track: 356 Speed: 133 kt Vertical rate: -29568 ft/min (from geometric altitude) UTC coupling: no TIS-B site ID: 0 Is this some sort of distance record?
All it takes is a few wrong 1s and 0s to make bad data. All the more likely to happen without a good antenna.
Thx freqhopping - that makes sense. I have to ask the questions: HOW many people here knew there was a : Emitter category: Space / transatmospheric ?? Guess that begs the next question: what platform would use this category - high-altitude balloons? (future/classified rocket planes?)
