Platform stabilizing systems

Apparatus for stabilizing a platform comprising:

• a. a stabilizing gyroscope including a substantially horizontal rotor for stabilizing said platform and adapted for converting a disturbing force into a precessing force;
• b. a frame carrying said stabilizing gyroscope securely mounted without gimbals at a set first location such that the axis of the rotor of said gyroscope is fixed with respect to said frame so as to effect a dominant precessing force offset 90.degree. in the direction of rotation responsive to said disturbing force at a first azimuth that induces a torque force on said axis of rotation in any direction from zero to 360.degree. in a horizontal plane about a predetermined center of said platform;
• c. a load carrying compartment;
• d. shifting means for shifting said load carrying compartment to move its center of gravity to a plurality of successive second locations and azimuths with respect to said frame to offset to a desired degree the torque force and the reactive precessing force;
• said shifting means carrying said load carrying compartment and being carried by said frame;
• and
• e. control means for detecting a slight change in attitude of said platform from a desired attitude, and a second azimuth of a force effecting a raising of a portion of said platform and causing said change in attitude and effecting via said shifting means a controlled shifting of said load carrying compartment to a new second location along a third azimuth offset from said second azimuth 90.degree. in a direction opposite the direction of rotation of said stabilizing gyroscope to establish the desired attitude;
• said control means being carried on said frame and connected with said shifting means so as to effect energization thereof for positioning said load carrying compartment at a new second location.
