The series of observations on the prismatic astrolabe with whole duration of observations of 44 years are continued. The long period series of observations on the astrolabe and zenith telescope Zeiss are revised. It is began monitoring of the point coordinates with the help of GPS receiver and it's repeted again the activity of observatory in the international coordinate net of IERS. It's continuing activity in the work of the international Lunar occultation service. It's carried out theoretical researches of the rotational motion of the Earth on the base of incalculation of the finite element method with other numerical and analytical methods for modelling of dynamical behaviour of the Earth.
