Satellite-borne equipment support with directional self-sensing capability

The invention relates to a satellite-borne equipment support with directional self-sensing capability, which comprises a support rod, a single-axis degree-of-freedom release joint, a double-axis degree-of-freedom release joint, an equipment support seat and a strain sensor, wherein the bottom of the support rod is connected with the single-axis degree-of-freedom release joint, and the top of the support rod is connected with the double-axis degree-of-freedom release joint to form a support rod assembly; the single-axis degree-of-freedom release joint is a single-axis hinge or a single-direction slotted spring; the double-axis degree-of-freedom release joint is a spherical hinge or a bidirectional slotted spring; and no less than one group of strain sensors are arranged on each support rod and are used for measuring strain information of the support rods in real time. Through strain measurement of the sensor on the support rod and derivation of a simplified mathematical model of the support, spatial pointing d
