In the sea area near Yangjiang in Guangdong and XichangSatellitesAt the launch center, the Long March 11 and Long March 3B were carried out successivelyLaunch vehiclesand all of them were a complete success. Long March 11 launch vehicleSuccessfully launched test No. 24C in the waters near Yangjiang in GuangdongSatellites, and the Long March-3BLaunch vehiclesThen the 57th and 58th Beidou navigation will be successfully sentSatellites。The successful launch of these two missions further demonstrates China's presenceAstronauticsStrength in the field.
Long March 11 launch vehicleYesRocketsA solid developed by the InstituteLaunch vehiclesIn this launch mission, it will successfully test the 24CSatellitesIt was sent into a predetermined orbit and made an important contribution to space science and technology experiments. For the first time, a 2-meter diameter fairing was used for this mission, which was enhanced compared to previous launchesRocketsadaptability and market competitiveness. Taking into account the conditions such as condensation and air salt spray that may be encountered by the Sea Launch, the technical team has further improved the automation of the launch process and improved the accuracySatellitesAbility to safeguard the environment. In addition, the Long March 11 andJielong-3 rocketUsing the same launch vessel, a long-range mobile launch from the sea was carried out, setting a new record for the shortest interval between sea launches, which was solidRocketslaid the foundation for high-frequency launches at sea.
Long March-3BLaunch vehicleswithExpedition OneThe upper stage was connected and became a pair of "gold partners", and jointly completed the 57th and 58th Beidou navigationSatellitesof launches. These twoSatellitesIt belongs to the middle circleEarth orbitSatellites, is the Beidou-3 globalSatellitesThe first group of MEOs launched after the completion and opening of the navigation systemSatellites。Long March-3BRocketswithExpedition OneThe combination of the upper stage once again showed a high degree of coordination and reliability in this mission. In order to ensure the success of this mission, the R&D team to:RocketsAdaptation has been made to further improve its reliability and adaptability. Since 2000, China's first Beidou navigation test was launchedSatellitesSince then, the Long March 3A seriesLaunch vehiclesIt has achieved a 100% launch success rate and is known as the "Beidou Special Train".
Long March 11 and Long March 3BLaunch vehiclesThe succession of the launch was marked by successionChina AerospaceA major breakthrough has been made in the cause. Long March 11RocketsSuccessful launch test 24CSatellites, which not only provided solid support for space science and technology experiments, but also demonstratedRocketsA new breakthrough in Sea Launch. , and the Long March-3BRocketswithExpedition OneThe upper stage "joined hands" again to navigate for BeidouSatellitesThe launch of the contribution to the continuationRocketsRecords of launches. Both launches were a complete success, proving once againChina AerospaceThe strong strength and technical level of the business.
ForChina AerospaceIn terms of development, both launches are of great significance.
