Definition

A computationally cheap approximate model that substitutes for a high-precision numerical iterative solver; here APCE substitutes for the Lambert solver to enable rapid uncertainty analysis.

Application Value

This term has application value in the design and analysis of cislunar space missions, supporting trajectory design, mission planning, and system optimization. Researchers can analyze its physical mechanisms and engineering applicability based on specific mission requirements to advance cislunar space exploration technology.
