Type Alias Position

Type declaration

• Optionalaltitude?: number

  In meters above MSL (but see issue #359)

  Generated

  from field: optional int32 altitude = 3;

• OptionalaltitudeGeoidalSeparation?: number

  Geoidal separation in meters

  Generated

  from field: optional sint32 altitude_geoidal_separation = 10;

• OptionalaltitudeHae?: number

  HAE altitude in meters - can be used instead of MSL altitude

  Generated

  from field: optional sint32 altitude_hae = 9;

• altitudeSource: Position_AltSource

  TODO: REPLACE

  Generated

  from field: meshtastic.Position.AltSource altitude_source = 6;

• fixQuality: number

  GPS fix quality (from NMEA GxGGA statement or similar)

  Generated

  from field: uint32 fix_quality = 17;

• fixType: number

  GPS fix type 2D/3D (from NMEA GxGSA statement)

  Generated

  from field: uint32 fix_type = 18;

• gpsAccuracy: number

  GPS accuracy (a hardware specific constant) in mm multiplied with DOP to calculate positional accuracy Default: "'bout three meters-ish" :)

  Generated

  from field: uint32 gps_accuracy = 14;

• OptionalgroundSpeed?: number

  Ground speed in m/s and True North TRACK in 1/100 degrees Clarification of terms:

  • "track" is the direction of motion (measured in horizontal plane)
  • "heading" is where the fuselage points (measured in horizontal plane)
  • "yaw" indicates a relative rotation about the vertical axis TODO: REMOVE/INTEGRATE

  Generated

  from field: optional uint32 ground_speed = 15;

• OptionalgroundTrack?: number

  TODO: REPLACE

  Generated

  from field: optional uint32 ground_track = 16;

• HDOP: number

  TODO: REPLACE

  Generated

  from field: uint32 HDOP = 12;

• OptionallatitudeI?: number

  The new preferred location encoding, multiply by 1e-7 to get degrees in floating point

  Generated

  from field: optional sfixed32 latitude_i = 1;

• locationSource: Position_LocSource

  TODO: REPLACE

  Generated

  from field: meshtastic.Position.LocSource location_source = 5;

• OptionallongitudeI?: number

  TODO: REPLACE

  Generated

  from field: optional sfixed32 longitude_i = 2;

• nextUpdate: number

  Estimated/expected time (in seconds) until next update:

  • if we update at fixed intervals of X seconds, use X
  • if we update at dynamic intervals (based on relative movement etc), but "AT LEAST every Y seconds", use Y

  Generated

  from field: uint32 next_update = 21;

• PDOP: number

  Horizontal, Vertical and Position Dilution of Precision, in 1/100 units

  • PDOP is sufficient for most cases
  • for higher precision scenarios, HDOP and VDOP can be used instead, in which case PDOP becomes redundant (PDOP=sqrt(HDOP^2 + VDOP^2)) TODO: REMOVE/INTEGRATE

  Generated

  from field: uint32 PDOP = 11;

• precisionBits: number

  Indicates the bits of precision set by the sending node

  Generated

  from field: uint32 precision_bits = 23;

• satsInView: number

  GPS "Satellites in View" number

  Generated

  from field: uint32 sats_in_view = 19;

• sensorId: number

  Sensor ID - in case multiple positioning sensors are being used

  Generated

  from field: uint32 sensor_id = 20;

• seqNumber: number

  A sequence number, incremented with each Position message to help detect lost updates if needed

  Generated

  from field: uint32 seq_number = 22;

• time: number

  This is usually not sent over the mesh (to save space), but it is sent from the phone so that the local device can set its time if it is sent over the mesh (because there are devices on the mesh without GPS or RTC). seconds since 1970

  Generated

  from field: fixed32 time = 4;

• timestamp: number

  Positional timestamp (actual timestamp of GPS solution) in integer epoch seconds

  Generated

  from field: fixed32 timestamp = 7;

• timestampMillisAdjust: number

  Pos. timestamp milliseconds adjustment (rarely available or required)

  Generated

  from field: int32 timestamp_millis_adjust = 8;

• VDOP: number

  TODO: REPLACE

  Generated

  from field: uint32 VDOP = 13;
