The paper centers on the aiming task that ensures the landing of a sliding reentry vehicle
(RV) with a rocket-assisted parachute non-destructive landing system. The vehicle is part
of an advanced manned orbiting spacecraft on small-sized launch sites on the territory of
Russia. Within the research we analyzed the factors that require the corrective action
concerning the aiming end point of the controlled letdown path with respect to the aiming
point of the RV landing. Findings of the research show that conventional aiming, which
uses the rated performance of the RV and atmosphere, does not provide the conditions
for the guaranteed high-precision RV casting because of the possible reduction of its real
maneuvering potential. As a result, the study introduces a method and an algorithm of
the aiming point bias of the non-destructive landing system start with the a priori statisti-
cal estimation of the possible RV side-step manoeuvre incompetence. Finally, the study
gives the results of numerical simulations confirming the effectiveness of the proposed
method and algorithm.
