Target Planner is an algorithm and interface embedded in STK SOLIS that enables users to easily plan and execute spacecraft targeting operations to maximize use of the spacecraft timeline.

  • Leverages STK/Access to seamlessly integrate targeting constraints; including temporal, distance, angle, lighting, etc…
  • Incorporates real-time knowledge of spacecraft agility to determine optimal slew durations
  • Establishes a proven process for rapidly creating and adapting complex spacecraft operations

Users configure the Target Planner by defining and assigning targeting configurations:

  • Target dwell duration
  • STK/Access constraints
  • Spacecraft orientation
  • Sequence(s) to command relative to target arrival and departure

target-planner-screenshotTargets are assigned priorities to help determine the scheduling when conflicts occur.

Target Planner output is a real spacecraft command sequence that can be executed by the flight software.

Time-based and target-based summaries are provided for review.

The Target Planner process utilizes real-time operating constraints rather than worst-case conditions to determine an optimal command schedule by giving preference to priority targets and expiring targets while minimizing slew times. A higher-priority target is guaranteed not to be missed due to the scheduling a lower-priority target.
