A method of determining an orbit of an orbital object includes computing predicted tracking measurement values based on the orbit computed from the initial conditions factoring in any modeled environmental forces and realistic maneuvers; computing the differences between the actual and predicted tracking measurements; determining an improved estimate of the initial conditions that reduces the measurement errors using a minimization or root finding algorithm; after the algorithm has converged, reviewing the hypothetical maneuvers in the force model, taking each value and determining which values came up as near-zero in the minimized solutions and which values came up as those of measurable thrust; determining overall burn duration using the first and last burn times; determining the thrust profile of the orbital object over the observation period using the integrated thrust values; and determining the actual maneuver based on the observation data.

The invention relates to a method for modeling the terrain property of a Wargame map by a grid matrix. The method comprises the following steps: firstly, determining an orthohexagonal grid form, i.e., a hexagonal grid, of the Wargame map, and selecting geographical environment factors which participate in modeling the terrain property; then, according to the dimension of the matrix grid and an externally tangent rectangle which surrounds each geographical condition factor, establishing an initial grid matrix on the basis of the geographical environment factors; then, determining an amount of grid points which simultaneously press and cover the geographical environment factors and the hexagonal grid in the grid matrix, and combining with the area of the hexagonal grid to calculate a pressing and covering area ratio of each geographical condition factor to the hexagonal grid; and finally, according to a terrain property judgment rule, determining the terrain property of the hexagonal grid. Through the method, the complexity of modeling the terrain property of the Wargame map is effectively lowered, and the efficiency of modeling the terrain property of the Wargame map is improved on the premise that modeling precision is guaranteed.
