This paper presents a description of the software implementation of methods for the precise calculation of orbital parameters for near-Earth space, as well as for the vicinity of Lagrange points. The programme is based on modern mathematical models and algorithms that ensure high accuracy and computational efficiency. Various perturbing factors are taken into account, and the capability of simulating the motion of spacecraft in complex gravitational environments is implemented. A comparison is made between the programme’s results and a well-known software solution for ballistic and navigational calculations.
