Rail atmosphere density detection test Satellite will effectively improve the accuracy of atmospheric density reverse detection accuracy

Xinhua News Agency, Beijing, July 29th (Reporter Zhang Quan) The reporter learned from the National Space Science Center of the Chinese Academy of Sciences that the rail atmospheric density detection test satellite was sent to the scheduled orbit by Lie Jian No. 1 launch rocket. Performing accuracy provides effective technical support for the aerospace aircraft rail forecast and collision warning.

The rail atmosphere density detection test satellite was jointly developed by the Sun Event and Space Weather Key Laboratory of the National Space Science Center of the Chinese Academy of Sciences and the Space Weather Key Laboratory and the Shanghai Academy of Teachers' Satellite Innovation Research Institute of the Chinese Academy of Sciences. The satellite is equipped with two global navigation satellite system (GNSS) receiver and is equipped with laser horn reflectors, which can be used for precision rail and atmospheric density.

According to reports, the traditional method of atmospheric density countermeasures requires higher stances of satellite operation. In order to obtain high -precision atmospheric density, the satellite facial quality ratio and damping coefficient must be accurately grasped. The irregular satellite, the damping coefficient of the welcoming area and the satellite surface changes over time, which has caused some difficulties in the density of the atmospheric density.

The orbital atmospheric density detection test satellite is a light -shaped satellite with a mass of 36 kg and 60 cm in diameter. The spherical satellite configuration is simple and has a certain face -to -face ratio, which can not only significantly reduce the impact of various parameter changes on the anti -density of the atmospheric density, but also can not be adjusted without frequent posture, which can significantly reduce the cost of satellite manufacturing.

It is reported that the research team will use the test satellite to verify the atmospheric density and high -precision anti -exploration technology to lay the technical foundation for building the atmospheric density detection constellation and support the dynamic correction of atmospheric density.
