The invention concerns a system for determining at least one parameter of at least one member ( 1 ) rotating with respect to a fixed structure ( 2 ), comprising, for each rotating member ( 1 ), an assembly comprising a transponder ( 3 ), a coder ( 5 ), a position sensor ( 6 ) and a device ( 4 ) for detecting the parameter or parameters issuing from the transponder ( 3 ); the said system also comprising a synchronisation unit ( 7 ) which is connected to each sensor ( 6 ) and to each detection device ( 4 ), the said unit comprising a device ( 7 a) for determining an activation position of the detection device ( 4 ) of an assembly when the transponder ( 3 ) of the assembly is in the transmission/reception cone of the communication means of the said detection device, and an activation device ( 7 b) able, by comparing the position of the coder ( 5 ) with the activation position, to activate the detection device ( 4 ) of the assembly in order to measure the parameter or parameters.
