초록 ▼

In an apparatus for orbit control of at least two co-located geostationary satellites a single interface is provided in the form of an orbit database for exchanging orbit and maneuver data between four independent decoupled function blocks of an orbit control system having a matched function scope, i.e. between a first function block for orbit determination and maneuver estimation/maneuver calibration, a second function block for maneuver planning, a third function block for monitoring the relative movement and a fourth function block for predicting specific events and ephemerides (FIG.

대표청구항 ▼

An apparatus for orbit control of at least two co-located geostationary satellites, comprising: means for consecutively calling up a plurality of function blocks of an orbit control system with a matched function scope in an indicated order via an orbit database which serves as interface between said plurality of function blocks and to which data is transferred in a defined format such that said plurality of function blocks obtain the required input data from the orbit database and if necessary supply results which are generated back to said orbit database; a) first function block means of said plurality of function blocks for obtaining orbit determination data based on the measurements of ground stations, said first function block means determines all parameters which are necessary for calculation of ephermerides in the form of lists containing position, velocity and other important orbit-relevant quantities in discrete time steps, as functions of the time or a desired time period, and calibration data of executed orbit maneuvers for co-located satellites and stores them in an orbit database; b) second function block means of said plurality of function blocks for maneuver planning, said second function block means accesses the results stored in said orbit database and calculates therefrom, parameters for orbit maneuvers so that a satellite at predetermined dates reaches a fixed desired orbit, again said parameters for orbit maneuvers are also stored in said orbit database; c) third function block means of said plurality of function blocks for monitoring and calculating, with the aid of said parameters for orbit maneuvers stored in said orbit database, relative movement of all co-located satellites and calculates the relative distances and velocities, resolved by components, between said co-located satellites for a desired period of time, said relative distances and velocities are also stored in said database, and d) fourth function block means of said plurality of function blocks, using information stored in said orbit database form said first, second and third function blocks for predicting specific events and ephemerides, and computes a detailed orbit ephemeris.
