[−][src]Module asterix::data_item
Defined Data Items that are used for formal parsing of data structs in categories
Structs
| ACASResolutionAdvisoryReport | Currently active Resolution Advisory (RA), if any, generated by the ACAS associated with the transponder transmitting the report and threat identity data |
| AircraftAddress | Aircraft address (24-bits Mode S address) assigned uniquely to each aircraft |
| AircraftIdentification | Aircraft identification (in 8 characters) obtained from an aircraft equipped with a Mode S transponder |
| AntennaRotationSpeed | Antenna rotation period as measured between two consecutive North crossings or as averaged during a period of time |
| CalculatedDopplerSpeed | Subfield of |
| CalculatedPositionCartesianCorr | Calculated position of an aircraft in Cartesian co-ordinates |
| CalculatedTrackVelocity | Calculated track velocity expressed in polar co-ordinates |
| CodeFx | |
| CommunicationsCapabilityFlightStatus | Communications capability of the transponder, capability of the onboard ACAS equipment and flight status |
| DataSourceIdentifier | Identification of the radar station from which the data is received |
| FlightLevelInBinaryRepresentation | Flight Level converted into binary representation |
| HeightMeasuredBy3dRadar | Height of a target as measured by a 3D radar. The height shall use mean sea level as the zero reference level |
| MBData | |
| MeasuredPositionInPolarCoordinates | Measured position of an aircraft in local polar co-ordinates |
| MessageType | This Data Item allows for a more convenient handling of the messages at the receiver side by further defining the type of transaction |
| Mode1CodeConfidenceIndicator | Confidence level for each bit of a Mode-1 reply as provided by a monopulse SSR station |
| Mode1CodeOctalRepresentation | |
| Mode2CodeConfidenceIndicator | Confidence level for each bit of a Mode-2 reply as provided by a monopulse SSR station |
| Mode2CodeOctalRepresentation | Reply to Mode-2 interrogation |
| Mode3ACodeConfidenceIndicator | Confidence level for each bit of a Mode-3/A reply as provided by a monopulse SSR station |
| Mode3ACodeInOctalRepresentation | Mode-3/A code converted into octal representation |
| ModeCCodeAndConfidenceIndicator | Mode-C height in Gray notation as received from the transponder together with the confidence level for each reply bit as provided by a MSSR/Mode S station |
| ModeSMBData | Mode S Comm B data as extracted from the aircraft transponder |
| RadarPlotCharacteristics | Additional information on the quality of the target report |
| RadialDopplerSpeed | Information on the Doppler Speed of the target report |
| RawDopplerSpeed | Subfield of |
| SectorNumber | Eight most significant bits of the antenna azimuth defining a particular azimuth sector |
| TargetReportDescriptor | Type and properties of the target report |
| TimeOfDay | Absolute time stamping expressed as Co-ordinated Universal Time (UTC) |
| TrackNumber | An integer value representing a unique reference to a track record within a particular track file |
| TrackQuality | Track quality in the form of a vector of standard deviations |
| TrackStatus | Status of monoradar track (PSR and/or SSR updated) |
| WarningErrorConditionsTargetClass | Warning/error conditions detected by a radar station for the target report involved. Target Classification information for the target involved |
