Jitter in telescope system will impact tracking precision and blur images. In order to achieve optimal telescope system design

improve precision of location and tracking

jitter in system must be evaluated. According to measurement principle of high sensitive piezoelectric accelerometer

build up jitter measurement system on vehicle telescope platform

measure jitter acceleration on vehicle platform while the telescope is static and rotating.Jitter acceleration signal are collected by data acquisition system. The digital signal are wavelet denoising

processed and use power spectrum estimation to analyze distribution properties of jitter frequency. The result shows that during rotation of telescope

jitter acceleration generated by vehicle platform is up to 0. 015 g n

maximum jitter signal frequency is about 67Hz

it also verifies that it is feasible to use high sensitive piezoelectric accelerometer to measure slight jitter signal.
