Planner

The Planner allows you to create and manage orbital maintenance plans for your spacecraft. Using optimization algorithms, the Planner computes a sequence of maneuvers to keep a spacecraft within defined orbital parameters over a given time window. Route: /maneuvers/planner

Page Layout

The Planner page has two main sections: a details panel on the left and a plan list on the right.

​

Toolbar

The top bar contains:

• Spacecraft Filter — multi-select dropdown to filter plans by spacecraft
• Group By — group plans by Spacecraft, Status, Plan Type, or None
• Time Range — bidirectional time filter (past and future plans)
• New Plan — opens the plan creation wizard
• Toggle Panel — show/hide the plan list

​

Plan List

The right panel lists all plans matching the current filters. Each row shows the plan ID, status icon, name, spacecraft, plan type icon, and creation date. Hover any element for a tooltip with details. Plans can be grouped by spacecraft, status, or plan type. Each group header shows the count and supports pagination (5 items per page) and collapse/expand. Status icons: Click a plan row to load its details in the left panel.

​

Plan Creation Wizard

Click New Plan to open the plan creation wizard. The wizard guides you through 5 steps. Steps 1–3 and 5 are shared across all algorithm types; Step 4 is algorithm-specific.

​

Step 1: Overview

Configure the plan metadata and select the optimization algorithm.

​

Step 2: Initial State

Displays the spacecraft’s state that will be used as the starting point for the optimization, which defaults to latest computed state vector. Users can select a different state vector if desired using the ID dropdown, or initialize the process with the latest public TLE.

​

Step 3: Time Range

Define the time window over which the optimizer should plan maneuvers. Set the Start Date/Time and End Date/Time in UTC. The end must be after the start. By default, the start is 3 hours from now and the duration is 3 days. Some algorithms may require a single Target Date/Time.

​

Step 4: Algorithm Parameters

This step varies by algorithm type. See the algorithm-specific documentation:

• SMA Maintenance — Step 4

​

Step 5: Review

Review the full plan configuration before submission. The review shows all configured parameters in editable summary cards. Click Create Plan to submit. For complex plans, the computation may run asynchronously — a progress dialog tracks the job until completion. On success, the new plan appears in the plan list.

​

Plan Details

Select a plan from the list to view its details in the left panel (visible in the page screenshot above).

​

Header

The header shows the plan name, plan type icon, and a more menu with actions:

​

Plan Information

​

Status Actions

Plans in Evaluation status can be approved or rejected using the action buttons in the header:

• Evaluation → Approved (plan is ready for execution)
• Evaluation → Rejected (plan is discarded)

​

Tabs

Analysis — Algorithm-specific visualization showing how the computed maneuvers maintain the target orbital parameter. See SMA Maintenance Analysis for details. Burns — Lists each individual maneuver in the plan: Activity — Timeline of plan events (creation, approval, rejection) with user attribution and timestamps.
