1、 Actively report the trip. For the history of residence in the administrative region where the medium risk area in Shanghai is located since November 18, the history of residence in Longchuan County, Yunnan Province since November 19, the history of residence in Harbin, Heilongjiang Province since November 26, the history of residence in Kunyu mansion, Haidian District, Beijing since November 28 Since November 29, those who have entered and returned to Hunan with a history of living in Shilihe lamp city and Jiamei Block C in Chaoyang District, Beijing, as well as high-risk epidemic related groups such as those who coincide with the activity track of the published cases, take the same means of transportation, close contacts and close contacts must take the initiative to report to their communities (villages) at the first time Report to the work unit (school) or the hotel where you live, and cooperate in various prevention and control measures such as isolation, medical observation and nucleic acid detection as required.

2、 Actively carry out nucleic acid detection. All personnel entering Hunan from other provinces need to check the communication big data travel card and Hunan resident health card. Those who come to Hunan and return to Hunan from provinces where the local epidemic has occurred within 14 days need to check the negative certificate of nucleic acid test within 48 hours, and do a nucleic acid test within 24 hours after arriving in Hunan. It is suggested that the other provinces enter Hunan and Hunan to arrive at the first destination of our province. They will hold the COVID-19 nucleic acid negative test within 48 hours (by sampling time) or do a nucleic acid test within 24 hours after arriving in Hunan Province.

3、 Pay attention to health code. Please pay close attention to the officially released epidemic information and case activity track, and continue to pay attention to the color of the health code of Hunan residents who are themselves and their families. Once the health code is found to be red or yellow, they should take the initiative to report to their community (Village), work unit or hotel at the first time, and cooperate with the implementation of relevant prevention and control measures. In principle, the people with electronic health code and red code of residents in Hunan Province shall be isolated locally, and epidemic prevention management measures shall be taken according to the investigation. Yellow code personnel should hold the negative nucleic acid test report according to local requirements before they can pass in an orderly manner, but they are not allowed to participate in gathering activities, go to public places and other crowd gathering areas.

4、 Reasonably plan travel. No cross-border tourism, no travel to the province (municipality directly under the central government, autonomous region) where the medium and high-risk areas are located. If it is not necessary, do not go to cities with local epidemic reports.

5、 Do a good job of personal protection. The general public should always maintain a good awareness of personal protection, develop the health habits of carrying masks with them, wearing masks in a scientific and standardized manner (especially when taking public transport and activities in public places), washing hands frequently, ventilation frequently, and maintaining a safe social distance; Do not get together, do not get together, and advocate a healthy lifestyle.

6、 Adhere to self health monitoring. In case of fever, cough, diarrhea, fatigue and other symptoms, wear disposable medical masks and masks above the level, go to the fever clinic for investigation and diagnosis and treatment in time, and try to avoid taking public transport in the process of medical treatment.

7、 Timely vaccination. The covid-19 vaccination is the most economical, effective and convenient measure to prevent and control the spread of new crown pneumonia, and it is the duty and obligation of every citizen to take the vaccine. COVID-19 is the most effective and convenient way to prevent and control the spread of the new crown pneumonia. Please comply with the vaccination conditions of COVID-19 people actively participate in COVID-19 vaccination, work together to build a universal immune barrier.

According to public information, there is no precedent in the industry for LEO satellites to carry remote sensing payload and communication payload at the same time. At present, the strategic position of Leo remote sensing satellites is becoming increasingly prominent. With the continuous improvement of satellite accuracy, the original data has doubled. At the same time, remote sensing, as an important means in scenes such as rescue and disaster relief, sea area monitoring and global target monitoring, needs to achieve minute level response.

Many factors limit the speed of remote sensing information acquisition. According to Chi Xiaofei, the existing remote sensing system adopts the periodic and batch operation mode, which has the problems of short satellite zenith crossing time and insufficient ground receiving resources, which is difficult to meet the needs of obtaining a large number of remote sensing information with low time delay. The integration of remote sensing and communication, combined with intelligent ground data processing system, is an effective way to improve the speed of emergency response.

Sixiang technology takes the analysis of massive remote sensing satellite data as the core technology. The company has accumulated decades of technical experience in remote sensing data extraction algorithm and data application. The core experts are from top institutions related to remote sensing, have rich national large-scale special combat experience, and have absolute professional advantages in satellite system planning, satellite measurement, operation and control, and comprehensive processing of Multi-source Satellite data, It is the top satellite application innovation enterprise in the domestic commercial aerospace field.

At present, Sixiang technology has achieved business implementation in government supervision, infrastructure engineering, urban planning, environmental protection supervision and other fields. In the field of Finance and insurance, it has reached cooperation with a number of insurance, banks and investment institutions to provide decision support in agricultural insurance, engineering insurance and commodity investment. Many products were launched on financial data platforms such as Xinhua Finance, Wande and flush.
