Designed by the CAST Institute (China Academy of Space Technology), a subsidiary of the Chinese aerospace group CASC and specialized in spacecraft design, the Tiantong-1 02 satellite will be operated by China Satellite Communications Co. Ltd, another CASC subsidiary which owns about ten communication satellites such as the ChinaStar and APStar. Tiantong-1 02 is the second satellite of China's first mobile communication network. It uses a Chinese DFH-4 satellite platform, and, according to its manufacturer CAST, has the highest payload mass utilization rate compared to other satellites of the same family. The project was launched in 2010 following the 2008 earthquake in Sichuan, where almost all ground communication networks were paralyzed. China had no mobile communication satellites at the time, so it had to lease services from foreign countries, such as Inmarsat in Europe, for its rescue teams.
Geostationary Transfer OrbitEOS-1 (previously known as RISAT-2BR2) is an imaging mission of ISRO using an active SAR (Synthetic Aperture Radar) imager to provide continuity of service for RISAT-2. The objective of the RISAT mission is to use the all-weather as well as the day-and-night SAR observation capability in applications such as agriculture, forestry, soil moisture, geology, sea ice, coastal monitoring, object identification, and flood monitoring, but also for military surveillance. Flight also carries 9 rideshare payloads, including Lithuanian NanoAvionics R2 satellite - pathfinder for their M6P cubesat platform, 4 KSM satellites of Kleos Space for a maritime geolocation constellation, and 4 Lemur satellites for Spire.
Low Earth OrbitTianqi (also transcribed Tiange) is a series of small Chinese experimental LEO comsats by Guodian Gaoke for IoT (Internet of Things) communications, which are also carrying a camera for educational purposes. Guodian Gaoke plans to operate an IoT constellation. The "Apocalypse Constellation" provides users with much-needed data collection and transmission services for terrestrial network coverage blind areas, which are widely used in marine, environmental protection, meteorological, forestry, geological, emergency, rescue and smart city industries to enhance China's global data network coverage and application capabilities are of strategic importance.
Sun-Synchronous OrbitGPS-IIIA (Global Positioning System) is the first evolution stage of the third generation of the GPS satellites. It consists of the first ten (known as "tranche") of GPS III satellites.
Medium Earth Orbit B1062 - Maiden Flight Of Course I Still Love YouThe Yaogan 30-01-01 to 30-01-03 (Remote Sensing Satellite-30-01-01 to 30-01-03) satellites, were launched by CZ-2C rocket from China's Xichang space center on 29 September 2017. The purpose is not confirmed, although the news reports hint towards a SIGINT mission, especially to detect ships by their radio emissions. They are also known as CX 5 by the manufacturer. The satellites are spaced by 120° in their orbit.
Low Earth OrbitGlonass-K are the third generation of satellite design for GLONASS satellite navigation system. GLONASS is a Russian space-based navigation system comparable to the similar GPS and Galileo systems. This generation improves on accuracy, power consumption and design life. Each satellite is unpressurized and weighs 935 kg, and has an operational lifetime of 10 years.
