FIELD: information transfer routing.

SUBSTANCE: invention relates to information transfer routing. The technical result is achieved by the fact that for routing the spacecraft coordinates are set in a two-dimensional spherical coordinate system, the angular distance between the spacecraft is calculated taking into account the change in the path length, equivalent to a degree of latitude, on the surface of the sphere when moving away from the equator and approaching the poles. Each spacecraft is located on the surface of a sphere described by orbits and is connected by inter-satellite links with four neighboring ones. Distances in kilometers, equivalent to one degree l_e in latitude d_ϕ at the equator and in longitude d_λ, are equal and are taken as the unit for calculating distances "absolute degree". The distance measured in latitude in degrees is converted into absolute degrees depending on the height of the latitude, taking into account the coefficient of change in the absolute length of a degree of latitude cosϕ.

EFFECT: increasing the accuracy of calculations of the shortest routing path, increasing the speed of operation and reducing the computational load of the onboard router of the spacecraft.
