There have been attempts to detect spacecraft maneuvers from determined states by comparing Keplarian parameters/orbital energy. The maneuver is detected if unexpected changes in the parameter values correlate with maneuver history. This study expands the problem to simultaneous maneuver-time and Delta-V estimation. The maneuver time and velocity at time of maneuver estimation is posed as an optimization problem, which utilizes the Lambert problem by considering two position vectors at the time of maneuver and at an epoch after the maneuver. The estimate of Delta-V could act as a critical parameter that can provide safety and effective monitoring of space assets.
