The invention concerns an adjustable positioning system according to 1 to 6 degrees of freedom. Said system is designed to position and maintain in position a load. It essentially comprises: (a) three isostatic supports (RE), bearing the load (CH) and set on a base, one to three of said supports including adjusting means; (b) N load pickup astatic supports bearing the load and set on a base, said astatic supports being gas actuators provided with sufficient gas reserve so that the force exerted by said supports is substantially constant during the adjusting phase. The invention is useful in particular for positioning and adjusting optical blocks of a power laser.
