FIELD: precision instrument making.
SUBSTANCE: invention relates to precision instrumentation and can be used in systems of initial orientation of objects. Substance of the method consists in the fact that according to the readings of two satellite navigation receivers (SNR) placed on a rigid base, the coordinates of both SNR are determined in a geocentric coordinate system (CS), by the values of which, the cosine of the vertical angle formed in the geocentric CS by vectors lying between the points of the SNR and between the beginning of the geocentric CS and the centre of mass of the object is determined, after which the base with SNR is turned relative to the centre of mass of the object into the horizon plane based on the current determination of the values of the cosine of the vertical angle by the measured current geocentric coordinates of the second SNR until the moment when this cosine is equal to one. Then according to readings of both SNR their geographical coordinates (latitude and longitude) are determined, and according to the geographical coordinates of the SNR, the angle of the azimuth of the roll axis of the object is determined as the azimuth of the orthodromic distance lying between the points of the SNR, at its initial point – the point of the centre of mass of the object.
EFFECT: high accuracy of determining the azimuth of an object.
