CAM Optimization

CAM (Collision Avoidance Maneuver) Optimization helps you find the best avoidance maneuver for an active conjunction event. A guided 5-step wizard sweeps through a range of delta-V magnitudes and maneuver directions, filters the results, and lets you select an optimal candidate to create a maneuver plan. Route: Opened from the Conjunction Classification page via the CAM Optimization button.

​

Wizard Overview

The CAM Optimization dialog is a 5-step wizard:

​

Step 1: Conjunction

Select the conjunction event and alert data that will be used for the avoidance maneuver computation.

​

Spacecraft Selection

The spacecraft is selected in the dialog header. Changing the spacecraft resets the conjunction selection.

​

Conjunction Selection

Use the dropdown to select an active conjunction (only conjunctions with a future TCA are shown). Conjunctions are sorted by TCA ascending, and the first one is selected automatically. Each entry shows the conjunction code with a risk shield icon. Once selected, the conjunction card displays the TCA (Time of Closest Approach) and the Secondary Object name.

​

Alert Selection

After selecting a conjunction, choose which alert (CDM) to use as the data source. Alerts are sorted by timestamp with the latest first, and the most recent alert is selected automatically. The alert card shows the Criticality level, Miss Distance (in meters), and PoC (Probability of Collision). Below the summary, the Primary Object and Secondary Object panels show the position vector, velocity vector, and position sigma in the RTN frame.

​

Step 2: Constraints

Configure the sweep parameters and thruster that control how candidate maneuvers are computed.

​

Hard-Body Radii

Hard-body radii are auto-populated from the selected alert’s CDM data but can be overridden manually.

​

Delta-V Range

Define the range of velocity changes to sweep through.

​

Angular Sweep

Define the range of maneuver directions to sweep through.

​

Thruster Selection

Select which thruster to use for computing burn parameters. The thruster’s specifications (thrust, ISP, max burn time, direction) are displayed for reference.

​

Step 3: Time Filter

Optionally restrict the maneuver execution time to specific windows between now and TCA. By default, no execution windows are defined and all maneuver times between now and TCA are considered. Click Add Execution Window to restrict the search to specific time ranges. Each window defines a start and end time using date-time pickers bounded between now and TCA. Only maneuvers within these windows will be considered. You can add multiple windows, but they cannot overlap — overlapping windows are flagged with a validation error. This step is optional — you can proceed to the next step without adding any windows.

​

Step 4: Direction Filter

Optionally constrain maneuver directions using a directional cone in RTN (Radial-Tangential-Normal) space. Set the mode to Inclusion (only within the cone) or Exclusion (avoid the cone), then define the cone parameters. This step is optional — leave the mode set to None to skip direction filtering. Running the computation: Clicking Next at the end of Step 4 triggers the sweep-filter computation. The system evaluates all combinations of delta-V magnitudes and sweep angles, applies the configured time and direction filters, and advances to Step 5 with the results.

​

Step 5: Options

Review the sweep-filter results, select a candidate maneuver, and create the maneuver plan.

​

Scatter Plot

The scatter plot displays all remaining candidates after filtering. The Y-axis always shows Delta-V (m/s). Use the tabs above the chart to toggle the X-axis between Miss Distance (post-maneuver, linear scale) and Collision Probability (post-maneuver PoC, logarithmic scale). Interactions:

• Hover a point to see a tooltip with candidate details (delta-V, miss distance, post-PoC)
• Click a point to select it — the point turns green and grows larger

​

Pipeline Statistics

A summary line below the chart shows the filtering pipeline:

N total candidates → X Pareto filtered, Y time filtered, Z direction filtered → M remaining

​

Selected Candidate Detail

When a candidate is selected, the detail panel shows:

​

Plan Name and Description

After selecting a candidate, fill in the plan details:

​

Creating the Plan

Click Create Maneuver Plan in the dialog footer to finalize. The system creates a maneuver plan linked to the conjunction event and the selected thruster. On success, the dialog closes and the new plan appears in the Burn Plan page.

​

Key Concepts

For foundational concepts like delta-V, Probability of Collision (PoC), miss distance, and conjunctions, see Core Concepts. The following concepts are specific to CAM optimization:

​

Sweep Angle

The direction of the avoidance maneuver in the orbital plane, measured in degrees. The system sweeps through a range of angles to evaluate maneuver effectiveness in different directions.

​

Pareto Filtering

After computing all candidate maneuvers, the system applies Pareto filtering to identify the optimal frontier — candidates where no other option is better in both delta-V cost and collision risk reduction. This eliminates dominated solutions, leaving only the most efficient trade-offs.
