Help / KnownX MPT / Mission planning

Conjunction assessment

How close the planned path comes to another spacecraft, and when.

Status: Implemented.

What is reported

KnownX MPT propagates the whole scenario ahead over a 3-hour window and reports, against the nearest other vehicle:

QuantityMeaning
Miss distanceThe smallest separation in the window
Time of closest approach (TCA)When that separation occurs
Relative speed at TCAHow fast the two are passing each other

The closest approach is marked on the Trajectory Map.

It follows your plan

If a mission sequence is scripted, the assessment replays it. Add or change a burn and the readout updates at once, which makes it straightforward to see what a planned manoeuvre does to the miss distance. The tutorial Plan an avoidance burn walks through this.

Scope

The assessment reports miss distance. Probability of collision needs uncertainty data for both objects and is not in this release. Planets and moons are excluded; contact with a surface is handled by the trajectory prediction.
