China's independent research and development of solar drones, high-altitude test flights, launching global positioning navigation satellites in Japan

On June 1, according to the official microblog of "CCTV News", China's self-developed new rainbow solar drone successfully completed the adjacent space flight test at an altitude of 20,000 meters. Solar drones are characterized by extra long voyages and can be left in the future for months to years. The success of this test marks that China has become the third country to master this technology after the United States and Britain. ”

Japan successfully launched Global Positioning Navigation Satellite "Guideway" No. 2

According to HNK TV station reported on June 1, at 9:17 on the morning of the 1st, Japan successfully launched a "guideway" No. 2 navigation satellite using the H2A type 34 rocket at the Seed Island Space Center in Kagoshima Prefecture. This series of satellites can greatly improve the accuracy of positioning systems used in smartphones, car navigation systems, and the like.

The "Guideway" series of satellites, like the US GPS and GPS, can provide positioning information for portable terminals such as smartphones. The satellites operate in special orbits, and each satellite stays around Japan for about 8 hours a day.

Japan has experimentally launched a "leading path" satellite seven years ago, and plans to launch three this year. If all the launches are successful, it will ensure that there will always be one or more "leading" satellites operating in the vicinity of Japan, thus laying the foundation for the official start of the service after the spring of next spring.

The GPS satellite positioning error in the United States is about 10 meters. If the GPS satellite and the "leading" series of satellites are used in combination, the positioning error can be reduced to a few centimeters, which greatly improves the positioning accuracy. To this end, the "Guideway" series of satellites is expected to promote the development of new technologies and contribute to social life and economic development. The main contents include improving the automation level of agricultural equipment and construction equipment, promoting the spread of drone transportation, and improving pedestrian navigation systems. Performance and so on.
