ARRANGEMENT FOR DEFINITION OF A FLYING VEHICLE'S LOCATION Russian patent published in 2007 - IPC G01S5/10 

FIELD: the invention refers to the field of radio navigation and may be used in the airborne equipment of satellites' navigational systems.

SUBSTANCE: the technical result is increasing accuracy of definition of the location of a flying vehicle due to exclusion of systematic error of radio navigational parameters' measuring, conditioned by non-identical measuring sections. The arrangement has the airborne equipment and the ground equipment of control stations. The airborne equipment has in-series connected an antenna, an antenna switch, users' navigational apparatus, a current coordinates indicator and a differential corrections indicator. The output of the users' navigational apparatus is connected with the information inputs of a decoder and of a switch whose first information input is connected with the input of the current coordinates indicator. The input of the differential corrections indicator is connected with the output of the first memory block, the second information input of a subtraction block is connected with the output of the second memory block whose signal inputs are connected with the signal outputs of the decoder. The synchronization inputs of the first and the second memory blocks and of the subtraction block are connected with the output of an delay element whose input is combined with the driving inputs of the switches and with the input of a differential circuit and is connected to the output of the synchronizer. The output of the differential circuit is connected with the input of nullification of the first memory block. The ground equipment of control stations is fulfilled in the shape of in-series connected a receiving antenna, a receiver, a delay block, a transmitter and a transmitting antenna.

EFFECT: increases accuracy of definition of the location of a flying vehicle.
