The Russian GLONASS Global Navigation Satellite System – operated by the Russian Aerospace Defence Forces – is currently the only global alternative to the American GPS fleet in operation that has global coverage of comparable precision.

On December 9, 2019 at 10:35 UTC the Russian “Progress MS-13” unmanned supply spacecraft docked to the International Space Station. The spacecraft was docked to the Russian “Pirs” module. The spacecraft delivered about 2500 kilograms of cargo for the six-member ISS crew.

On December 8, 2019 at 12:47 UTC, the private U.S. unmanned supply spacecraft, the "Dragon” SpX-19 (CRS-19 flight), was successfully docked to the International Space Station. The linkup operation was carried out with the help of the giant 17-meter Canadarm. The capture with Canadarm-2 was performed by Italian astronaut Luca Parmitano at 10:05 UTC. The Dragon spacecraft was maneuvered into position and attached to a berthing port on the space station's Harmony module. This docking marked the 19^th time a Dragon spaceship has reached the space station, counting a demonstration flight in 2012. The Dragon spacecraft delivered 2617 kilograms of supplies, equipment and research investigations for the station’s crew.

On December 7, 2019, at 08:52 UTC, the “Kuaizhou-1A” (“Speedy vessel”) rocket-carrier was launched from the Taiyuan Satellite Launch Center in north China's Shanxi Province. The rocket orbited 6 small satellites. Two solid-fueled “Kuaizhou-1A” rockets were launched from the same Launch Center, demonstrating a further advance in China’s aim for a quick-response, on-call satellite launch capability.

On December 7, 2019, at 02:55 UTC, the “Kuaizhou-1A” (“Speedy vessel”) rocket-carrier was launched from the Taiyuan Satellite Launch Center in north China's Shanxi Province. The rocket orbited the “Jilin-1 02B” high-resolution remote-sensing satellite.
