Aviation attitude message

Aviation attitude messages store the attitude of an aircraft computed by an attitude and heading reference system (AHRS): pitch, roll, accelerations, turn rate and track.

Fields

timestampDateTimes
Moment the message refers to, in UTC. FIT stores it as seconds since the FIT epoch (December 31, 1989, 00:00:00 UTC); decoders usually expose it as a regular date.
timestampMsUint16ms
Millisecond part of the timestamp, for sub-second precision.
systemTimeUint32[]ms
Device system time, in milliseconds, associated with each sample of the message.
pitchFloat64[]radians
Pitch angle, from -π/2 to +π/2.
rollFloat64[]radians
Roll angle, from -π to +π.
accelLateralFloat64[]m/s^2
Lateral acceleration.
accelNormalFloat64[]m/s^2
Normal (vertical) acceleration.
turnRateFloat64[]radians/second
Turn rate.
stageEnum[]
State of the attitude computation: failed, aligning, degraded or valid.
4 possible values
- failed
- valid
- aligning
- degraded
attitudeStageCompleteUint8[]%
Completion of the current attitude stage.
trackFloat64[]radians
Track angle or heading, from 0 to 2π.
validityEnum[]
Which of the values are valid.
13 possible values
- trackAngleHeadingValid
- pitchValid
- rollValid
- lateralBodyAccelValid
- normalBodyAccelValid
- turnRateValid
- hwFail
- magInvalid
- noGps
- gpsInvalid
- solutionCoasting
- trueTrackAngle
- magneticHeading
mesgNumString
Global message number identifying the kind of message. Decoders use it to know which profile to apply to the data.
