The Python Mode-S Decoder (dev-2.0 branch) The Python Mode-S Decoder (2.0-dev)
========================================== ==========================================
Python library for Mode-S message decoding. Support Downlink Formats (DF) are: Python library for Mode-S message decoding. Support Downlink Formats (DF) are:
- Automatic Dependent Surveillance - Broadcast (ADS-B) (DF17) - Automatic Dependent Surveillance - Broadcast (ADS-B) (DF17)
- aircraft information that contains: ICAO address, position, altitude, velocity (ground speed), callsign, etc. - TC=1-4 / BDS 0,8: Aircraft identification and category
- TC=5-8 / BDS 0,6: Surface position
- TC=9-18 / BDS 0,5: Airborne position
- TC=19 / BDS 0,9: Airborne velocity
- TC=28 / BDS 6,1: Airborne status [to be implemented]
- TC=29 / BDS 6,2: Target state and status information [to be implemented]
- TC=31 / BDS 6,5: Aircraft operational status [to be implemented]
- Mode-S Comm-B replies - Additional information in response to SSR interrogation, such as: true airspeed, indicated airspeed, mach number, wind, temperature, etc.
- DF20: Altitude - Mode-S Comm-B replies (DF 20 / 21)
- DF21: Squawk code
- BDS 2,0 Aircraft identification - BDS 1,0: Data link capability report
- BDS 2,1 Aircraft and airline registration markings - BDS 1,7: Common usage GICB capability report
- BDS 3,0 ACAS active resolution advisory - BDS 2,0: Aircraft identification
- BDS 4,0 Selected vertical intention - BDS 2,1: Aircraft and airline registration markings
- BDS 4,4 Meteorological routine air report - BDS 3,0: ACAS active resolution advisory
- BDS 5,0 Track and turn report - BDS 4,0: Selected vertical intention
- BDS 5,3 Air-referenced state vector - BDS 4,4: Meteorological routine air report
- BDS 6,0 Heading and speed report - BDS 5,0: Track and turn report
- BDS 5,3: Air-referenced state vector
- BDS 6,0: Heading and speed report
- DF4 / DF20: Altitude code
- DF4 / DF21: Identity code (squawk)
