On the night of September 29, 2011, China's newly developed first target vehicle Tiangong-1 was successfully launched.  Amid cheers from all over the country, GRT also received good news: Guangruntong's independently developed optical fiber module and optical fiber network card have been successfully applied in the data room of the satellite measurement and control center, providing a strong guarantee for the key equipment of the satellite data measurement and control room serving as the measurement and control mission for this launch.

Tiangong-1 is the name of China's first space laboratory. The target spacecraft to be launched will complete docking missions with Shenzhou-8, Shenzhou-9 and Shenzhou-10 spacecraft within two years, thus establishing the first Chinese space laboratory.  The launch of Tiangong-1 is an important milestone in the development of China's manned space program.  Among them, the satellite measurement and control center is responsible for the important measurement and control tasks in this launch.

 GRT provides a strong guarantee for the safe and stable operation of the China Satellite TT&C Center and the successful launch of Sky1. The Xi 'an Satellite TT&C Center in China (that is, the communication data backup center in beijing aerospace control center) is the operation, control and management center of the China Satellite TT&C network, and is also the central node of the China Satellite TT&C network.  Xi 'an TT&C Center has fixed TT&C stations and three mobile TT&C stations in Weinan, Nanning, Kashgar, Xiamen, Qingdao, Changchun and Jiamusi, as well as foreign TT&C stations.  The data room of satellite TT&C center carries many key tasks such as tracking and measuring spacecraft, receiving and processing spacecraft telemetry parameters, etc.  Stable and reliable optical fiber modules and optical fiber network cards are especially critical for the data transmission task of satellite TT&C communication data room. After careful evaluation and selection of many optical fiber modules and optical fiber network card power brand suppliers by the expert group,  GRT power supply stands out for its high availability and excellent quality.

GRT (Beijing Guangruntong Technology Development Co., Ltd.) was established in April 2008, and its headquarters is located in Beijing Zhongguancun High-tech Park.  GRT is a high-tech enterprise with strong strength, integrating research and development, production and sales, and possessing independent intellectual property rights and independent brands.

GRT brings together a group of senior research and development personnel who have been engaged in optical communication industry for a long time, all of whom come from manufacturers of network connection, data transmission, optical communication and interface conversion. GRT has an average of more than 15 years of communication product research and development experience.  The company has been committed to the research on the core technologies of the optical fiber industry, and has established cooperative relations with many universities and scientific research institutions to lead the company's technology research and development with the market demand trend, making the technology and function of products in the industry leading position.

In this project, GRT adopts a flexible and decentralized intelligent monitoring and management scheme according to users' requirements for optical transmission, which greatly upgrades the reliability, usability and maintainability of the satellite monitoring and control power supply system, provides a strong guarantee for the safe and stable operation of China's satellite monitoring and control center and the successful launch of "Sky One" and makes outstanding contributions to China's space industry.
