Abstract: It is proposed that measuring information about angular motion of spacecraft can be received form gryrostabilized platform, angular velocity measurers or having no platform system of attitude determination. In this case, angular position of orientation object is determinated by integration of kinematic equations of angular motion according to information received from angular velocity measurers or one-axis gyrostabilizers. Though the output of gyrostabilizers are increments of quasicoordinates, this information is equivalent to measuring of angular velocity vector in basis connected with spacecraft.
