METHOD OF INERTIAL-SATELLITE POSITIONING OF MOBILE OBJECTS Russian patent published in 2016 - IPC G01C21/00 

FIELD: aviation.

SUBSTANCE: invention relates to aerospace instrumentation and can be used in systems for determining coordinates of mobile objects (MO) using a complex method of navigation functionally combining inertial and satellite methods, and can be used in high-precision positioning of MO, as well as during flight of aircraft (AC) in difficult navigation conditions. Technical result is higher accuracy. For this purpose, between the orbits of satellites and MO is placed aerostat suspension (AS) with equipment, performing search, capture and automatic tracking of constellation of visible satellites and MO in response to control-correction station (CCS) and MO. AS transceivers transmit navigation information to ground-based tracking station (CCS) and to consumer (MO). Besides, an optical apparatus for monitoring and tracking of stars in order to correct an inertial navigation system (INS) and local Cartesian coordinate system are mounted on AS. Supposed to be launched in stratosphere several (4-5) AS, radio and optically connected to each other and to CCS, which geodetically accurately anchored to the received local coordinate system. So, local differential navigation system (LDNS) with observation radius of 50-200 km is forming.

EFFECT: knowing sufficiently accurate position of supporting CCS and using radio-and optical range signals as well as signals of Doppler frequency shift, coordinates and velocity vectors of AS and MO can be accurately determined by increasing zone and time of MO availability.
