one rocket launch multi-satellites launching mode
one rocket launch multi-satellites strategy involves the sequential deployment of multiple satellites or spacecraft into orbit using a single rocket,representing an advanced approach to space launches.The successful deployment of multiple payloads with a single launch signifies an enhancement in the capabilities of carrier rockets.This method effectively increases rocket carrying capacity and reduces launch costs,making it a common practice in the current space industry.
Internationally,the launch of multiple stars with one arrow is commonly used in two ways.The first is to send several satellites at a time into the same or nearly the same orbit;The second is to release satellites in batches,with each satellite entering a different orbit.Most of the satellites launched from multiple satellites are micro-small satellites in low Earth orbit.
Recently launched one rocket launch multi-satellites
On May 21,China launched the Wuhan-1 satellite and the Ultra-low orbit Technology test satellite into space using the Kuaizhou-11 carrier rocket from the Jiuquan Satellite Launch Center.The satellites successfully entered the scheduled orbit and the launch mission was a complete success
Record for the highest
On June 7,2023,a single arrow was launched with 26 stars!Set a new record for China’s launch vehicle.It was successfully lifted off from Jiuquan Satellite Launch Center by a Lijian 1 Yuan-2 carrier rocket.The previous record was set by the Long March 8 carrier rocket in 2022,which put 22 satellites into orbit.
Efficient solution for one rocket launch multi-satellites
The number of separated satellites is large , not only to ensure that the satellite can be successfully separated,but also to ensure the accuracy of the satellite into orbit,which is relatively difficult.Each separation of the stars and arrows is closely focused on the measurement and control data,and eventually each satellite is accurately sent to the predetermined orbit.
In the process,it is necessary to solve the layout problem of the satellite in the fairing,and consider the different unlocking methods of the satellite and the motion deviation caused by the separation of energy.
