Relation

Relation is the position and motion of the observed (i.e. the target) relative to the position of the observer. This information is reported in a number of ways, all of which are listed in the Relation Terminology table. In each case, the target’s motion is given with respect to the unit observing the contact. It is not necessary for this to always be the case, but if the observer is reporting to another unit regarding the target, it is required to give the target’s position and motion in relation to the position of the unit receiving the report.

RELATION TERMINOLOGY

TERM DEFINITION
Inbound (velocity) Contact moving toward the unit at specified velocity in kilometers per second
Outbound (velocity) Contact moving away from the unit at specified velocity in kilometers per second
X by Y Gives the distance to the contact in hundreds of kilometers from the units position. ‘Positive X’ Is contact distance in front. and ‘Negative X’ is contact distance behind the unit. ‘Positive Y’ and ‘Negative Y’ gives the distance to the right and left respectively.
Up (distance) Unit is between the contact and the orbital plane at the specified distance (in hundreds of kilometers) from unit.
Down (distance) Unit is between the unit and the orbital plane at the specified distance (in hundreds of kilometers) from unit.
Crossing Right/Left The contact will cross the unit’s currant heading from the right or left (up or down is also possible)

EXAMPLES OF TERMINOLOGY USE

REPORT GIVEN EXPLANATION
‘Hostile, 10 by 5 down 2, lnbound 20’ A hostile target is 1000 kilometers in front of, 500 kilometers to the right of, and 20 kilometers in the direction of the orbital plane from the unit. and is closing at 20 kilometers per second.
‘Increase plus 5, turn right 45’ unit increases currant velocity by 5 kilometers per second, and turns to the right 45° from its current direction
‘New course. Left 10, decrease 25’ New direction of travel 10° to the left, and velocity is reduced by 25 kilometers per second
