Definition
Trajectory optimization technique that discretizes optimal control problems using pseudospectral methods and solves them via convex optimization, achieving higher convergence rate and solution accuracy than Euler or Runge-Kutta methods.
Application Value
在轨道设计阶段，该方法可用于求解低能量转移轨道，减少推进剂消耗。该优化方法计算效率高，适合处理带约束的轨迹优化问题。
