The ionospheric altimeter developed by the Institute of Electronics of the Chinese Academy of Sciences was accepted by the National Weather Service
China Instrument Network Instrument R&D In June 2017, the CSA-DIS digital ionospheric altimeter developed by the Institute of Electronics of the Chinese Academy of Sciences passed the site acceptance of the National Meteorological Bureau in Nanning, Guangxi and was officially put into the space weather observation of the National Weather Service. Business operation.
This is the first time that the second-generation ionospheric altimeter product developed by the Institute of Electronics has been purchased by the relevant national business departments, marking the completion of the transformation of the equipment from research to production.
In September 2016, the electronics company obtained the procurement task for the ionospheric altimeter equipment in Nanning, Guangxi, through an open bidding. Under the leadership of the Department of Science and Technology and the Quality Department, the research team completed the production, assembly and integration testing of products within less than half a year's development cycle, and conducted product reliability, environmental compliance, etc. in accordance with relevant national standards. Tripartite test and field test run. At the acceptance meeting, experts from the National Satellite Meteorological Center and the Institute of Geology and Geophysics of the Chinese Academy of Sciences believed that the functions and performance indicators of the ionospheric altimeter product of the Institute of Electronics met the requirements of the procurement contract and could be put into operation and use. pass the inspection.
The ionospheric altimeter is essentially a short-wave pulse detection radar and its operating frequency covers the entire short-waveband, typically 1-30 MHz. The ionospheric altimeter is transmitted vertically upwards through the transmitting antenna and received at the same location. The amplitude, frequency and time delay of the ionospheric reflection echo are measured to obtain the relationship between the signal reflection height and frequency (ie, the frequency height diagram). Processing data products such as ionospheric density profiles and critical communication frequencies to provide high-resolution ionospheric environmental monitoring information for communications, reconnaissance, navigation, measurement and control, and aerospace activities.
Since 2009, under the support of the “863†and other topics, the Institute of Electronics and the National Satellite Meteorological Center of the China Meteorological Administration have cooperated to complete the CAS-CADI ionospheric altimeter and integrated development, and successively built the Xinjiang Kezhou for the National Weather Service. , Qinghai Dulan, Nanning, Guangxi, Xi'an, Shaanxi, Wuhan and other ionospheric observation stations. In order to realize the nationwide production of the ionospheric altimeter, the Institute of Electronics developed a new generation of ionospheric altimeters. In 2013, the CAS-DIS digital ionospheric altimeter system was developed. This system is fully autonomous Property rights and technical indicators are at the international advanced level. In 2015, China Earthquake Administration purchased the product and built an ionospheric observation station for scientific research in Ganzi, Sichuan. In addition to the Nanning station in Guangxi, the Institute of Electronics will soon build the Xiamen Ionospheric Altimeter Observation Station for the China Meteorological Administration.
