摘要：AbstractThe objective of this paper was to investigate the orbital velocity changes due to the effect of ground based laser force. The resulting perturbations of semi-major axis, miss distance and collision probability of two approaching objects are studied. The analytical model is applied for low Earth orbit debris of different eccentricities and area to mass ratio and the numerical test shows that laser of medium power ∼5kW can perform a small changeΔV‾of an average magnitude of 0.2cm/s which can be accumulated over time to be about 3cm/day. Moreover, it is confirmed that applying laserΔV‾results in decreasing collision probability and increasing miss distance in order to avoid collision.
