POGO instability is one of the most important dynamical problems of space vehicles. The mechanism of the POGO instability is briefly clarified by a simple free-free system which consists of two masses, a spring, and a damper, followed by POGO stability matrix algorithm, POGO stability single transfer method, and POGO stability analysis estimation method. The adaptability of these POGO stability analysis of these POGO stability analysis is illustrated through an example. After important parameters related to POGO instability are discussed, the reliability analysis of POGO stability and its criteria are also introduced. POGO is the study of structural instability of the rocket body structural system and the longitudinal coupling of the propulsion system. Under the condition of POGO, longitudinal self-stimulating non-convergent vibration of the space vehicle is caused which is similar to the ever-jumping pogo stick and hence was given the name.
