This element consists of:

- One or more device data entires. Each contain(s):
- One TrackDataType element
- One PositionalDataType element
- Up to one RemarksDataType elements

When coupled with the source value, the resulting data tuple must be unique.

This entity must be populated with one of the listed set of values.

The contents of this entity must comply with MIL-STD 2525B.

This element is provided as a means for device messages to send special data in the message that is not represented elsewhere.

- Definitions:
- Altitude is defined as the distance above ground level (AGL).
- Depth is defined as the distance below ground level.
- Elevation is defined as the distance above/below mean sea level (MSL).

Course is defined as the rotational measurement clockwise from the line of true North to the direction of motion of a specific JBFSA track.

The Figure of Merit (or fom) describes the estimated error in the position. The following table (extracted from the MTS-EXPORT-INTERFACE-SPEC v4.3) relates the fom value to the estimated position error.

FOM | Estimated Position Error |
---|---|

1 | <= 25 meters |

2 | <= 50 meters |

3 | <= 75 meters |

4 | <= 100 meters |

5 | <= 200 meters |

6 | <= 500 meters |

7 | <= 1000 meters |

8 | <= 5000 meters |

9 | > 5000 meters |

Inclination is defined as the rotational measurement from the horizontal plane to the direction of motion of a specific battlespace object at a specific location where the positive angle is vertically upward.

Horizontal accuracy is defined as the one-dimensional linear distance representing the uncertainty in the horizontal plane in terms of probable circular error for a battlespace object.

Altitude accuracy is defined as the one-dimensional linear distance representing the uncertainty in terms of probable error range for the vertical axis of a battlespace object.

Course accuracy is defined as the rotational measurement of a sector that represents the uncertainty range in the estimate of the course at a specific location. The sector is bisected by the course.

Speed accuracy is defined as the numeric value that denotes the uncertainty range in the estimate for the speed at a specific location where the speed estimate falls at the center of the accuracy range.

Inclination accuracy is defined as the rotational measurement of a vertical sector that represents the uncertainty range in the estimate of the inclination at a specific location. The sector is bisected by the inclination.

Reliability is defined as the specific value that represents, for intelligence purpose, the general appraisal of the source in graded terms to indicate the extent to which it has been proven it can be counted on or trusted in to do as expected.

This entity must be populated with one of the listed set of values.
