PCT No. PCT/FR98/00192 Sec. 371 Date Oct. 5, 1998 Sec. 102(e) Date Oct. 5, 1998 PCT Filed Feb. 3, 1998 PCT Pub. No. WO98/35207 PCT Pub. Date Aug. 13, 1998The rate gyro according to the invention comprises, in one optical block, three optical cavities (B, C, D) of square shape which are devised in such a way that each of the corners of a cavity (B, C, D) coincides and communicates with the corner of another cavity, a control mirror (M4 to M6) or reading mirror (M1 to M3) being associated with each pair of coincident corners, the three cavities (B, C, D) communicating with a cathode chamber (CK) by way of three cathode capillaries (CK1 to CK3) with an equilibration chamber (CE) by way of three equilibration capillaries (CE1 to CE3). The control mirrors (M4 to M6), the reading mirrors (M1 to M3), the cathode capillaries (CK1 to CK3), the equilibration capillaries (CE1 to CE3) and the anodes are mutually symmetric according to a symmetry of revolution of order 3 about the activation axis DELTA (that is to say may be deduced from one another by a 120 DEG rotation about the axis DELTA ).
