Introduction

The telescope system is the core part of various telescopes and is widely used in astronomical observation, space remote sensing, geodesy, weapons and equipment, culture and education, etc.

Sports, culture, entertainment, tourism and other fields. With the advancement of science and technology and the development of social economy, the application scope of telescopes is expanding.

The industry has taken shape as the output of products has gradually increased.

The formulation of this document will promote the consolidation of the achievements of telescope technology progress, promotion and application, and development, and will have a great impact on the technology of the telescope manufacturing industry.

At the same time, as it is based on international standards, it provides support for international technical communication and it brings convenience to commercial trade and creates conditions for "Made in China" to go global.

In view of the above reasons, the terminology of various types of telescopes is standardized and regularized according to the technical characteristics and uses of the telescope system.

It is very necessary.
