Although a number of spacecraft have operated in halo orbits in the Earth-Sun system since then, [11] China was the first to realize Farquhar's original idea of a communications relay satellite in a halo orbit around the Earth-Moon L 2 point. [12] The satellite is based on the Chang'e 2 design. [13] It utilizes the CAST100 small satellite bus ...
The Queqiao relay satellite was inserted in a halo orbit around the Earth-Moon L 2 since 2018. China planned another relay satellite, called Queqiao 2, to support and supplement Queqiao-1. [11] [14] Originally, the idea was to design the relay satellite as an improved version of the Queqiao and launch it together with the Chang'e 7 probe.

The Hongtu-1 (Chinese: 宏图一号), known commonly by its English-language name PIESAT-1 and infrequently as Nuwa-1, is a Chinese commercial X-band interferometric synthetic aperture radar (InSAR) satellite constellation performing Earth observation missions in Sun-synchronous orbit. [1] [2] Hongtu-1 satellites are intended to map global non ...
The new system is a constellation of 35 satellites, which include 5 geostationary orbit satellites for backward compatibility with BeiDou-1, and 30 non-geostationary satellites (27 in medium Earth orbit and 3 in inclined geosynchronous orbit), [72] that offer complete coverage of the globe.

Earth observation satellite missions developed by the ESA as of 2019. Earth observation satellites are Earth-orbiting spacecraft with sensors used to collect imagery and measurements of the surface of the earth. These satellites are used to monitor short-term weather, long-term climate change, natural disasters.
The four satellites of the Fengyun 1 (or FY-1) class were China's first meteorological satellites placed in polar, Sun-synchronous orbit. [6] In this orbit, FY-1 satellites orbited the Earth at both a low altitude (approximate 900 km above the Earth's surface), and at a high inclination between 98.8° and 99.2° traversing the North Pole every 14 minutes, giving FY-1-class satellites global ...
