F10.7 <= 100 - low level; 100 < F10.7 < 150 - medium level; F10.7 >= 150 - high level

                        

                        Orbit 86328(15) - the first burn bulding the descent orbit  DV1=9.3 m/s.

                                                    After burn altitude Hmin= 188.2 km, Hmax= 219.2 km.

                       Orbit 86329(16) - the descent orbit second impulse DV2=10.4 m/s.

                                                                 After burn altitude Hmin = 158.9 km, Hmax= 218.5 km.

                       Orbit 86331(02) - the final braking impulse until fuel supply is fully 

                                                     consumed value  DV3=28 m/s.

                                                    The estimated coordinates of the unburnt fragments 

                                                    dispersion centre  j = 40Н S.L., l = 160Н W.L. 

                                                    in the target dumping area.

                                                    Estimated outward dispersion of the unburnt fragments

                                                    ±1500 km along the flight trajectory 

                                                    ±100 km in lateral direction.
