Scientific paper

The initial coordinates and velocity components of Halley's comet have been obtained along with parameters describing the nongravitational forces. Orbital computations have been carried out for the two models of nongravitational forces: Marsden-Sekanina's model and the impulse one. In the second case - the Medvedev impulse model - the nongravitational effects are reduced to small instantaneous changes of the orbital velocity vector at perihelion passage times of comet (or times close to the above) determined from observations. Both orbits give reasonable residual for normal places over the 1759 - 1986 time interval.
