Foreword

This standard is drafted in accordance with the rules given in GB/T 1.1-2009.

Introduction

With the development of ground observation technology and remote sensing application requirements, the number of orbiting satellites is increasing, the resolution of satellite payload (package Including temporal resolution, spatial resolution, radiation resolution, spectral resolution, etc.), the amount of raw data acquired at the same time Doubling, resulting in satellite links need to transmit the information rate is getting higher and higher. In order to alleviate the continuous growth of remote sensing observation and data transmission capacity Force is difficult to significantly enhance the contradiction, broadband high-speed transmission has become the inevitable trend of the development of satellite data transmission.

In order to solve the contradiction between remote sensing information and data transmission capacity, double circular polarization frequency reuse, Ka frequency data transmission, high order modulation and demodulation And efficient coding and decoding, variable code modulation (VCM) data transmission system has become the development of satellite data transmission to the development trend, the corresponding The terrestrial data receiving system also proposed a higher, updated technical requirements. S/X/Ka three-band terrestrial receiving system for low-range remote sensing Satellite downlink data receiving, recording, will become the remote sensing satellite data ground receiving system development trend. Due to the lack of appropriate standards and regulations Fan, making S/X/Ka tri-band low-frequency remote sensing satellite data ground receiving system design and construction of the lack of technical indicators and performance evaluation The basis of price. Research and development of S/X/Ka tri-band low-frequency remote sensing satellite ground receiving system technical requirements for the development of engineering systems, Test acceptance to provide technical indicators to develop and performance evaluation basis, reduce the technical risks of construction, has become a ground receiving system construction in a Key and critical technical requirements.

This standard is based on the development of satellite observation at home and abroad and the technical requirements of the ground receiving system, combined with the current domestic and foreign Technical level and development capability of S/X/Ka tri-band low-frequency remote sensing satellite ground receiving system function and technical specifications and so on.

For other low-orbit satellite ground receiving systems that receive high-rate satellite data, such as X, Ka single-band and S/X, S/Ka dual band Face receiving system can refer to the use.

1 Scope
