As a subsidiary() of Chin a Aerospace Science and Technology Corp, the academy is the major rocket developer in the country The rocket is tasked with sending satellites to high-altitude orbits such as the geosynchronous transfer and inclined(的) geosynchronous orbits. It can also be used to ...
The super-hot turbulent-current layer (SHTCL) theory offers an attractive opportunity for laboratory and astrophysical applications of the magnetic reconnection. New data on the mechanism of magnetic energy transformation into kinetic and thermal energie
Satellite Communications Toolbox™ is a tool that provides standards-based tools for designing, simulating, and verifying satellite communications systems and links. The toolbox enables you to model and visualize satellite orbits and perform link analysis and access ...
The present invention discloses a physically discrete satellite system architecture to address maintenance and replacement of satellites in orbit, to enhance rapid response capacity satellites. 本发明根据飞行任务的需求将卫星的功能分解为I个基本功能,采用N个航天器模块来实现所述的I个基本功能. The present ...
3d). As a result, along these high-symmetry directions the crossings are protected, leading to six inequivalent Dirac points emerging in the polariton spectrum—we call these satellite Dirac points (SDPs) to distinguish them from the CDPs. As we will see below, these SDPs belong to the type...
satellite ranging system, while with SLR and Swarm, the gravity field solutions can only be retrieved from the tracking of the spacecraft orbit perturbations, inevitably resulting in lower spatial resolution. In the case of Swarm, the monthly gravity fields are limited to spherical harmonic degree ...
