At 17:05:05 pm on February 5, 2021, the os-x6b new intelligent suborbital rocket and “Chongqing Liangjiang star” independently developed by zero one space technology Group Co., Ltd. (hereinafter referred to as zero one space) was successfully launched at a launch site in Northwest China. The test load was successfully separated and the whole flight was normal. The total length of the rocket is 9.4 meters, the flight time is about 580 seconds, and the maximum flight altitude is about 300 km. This launch successfully completed a number of key technical verification, achieved intelligent launch and flight to the greatest extent, obtained a large number of real flight environment data, and the test was a complete success.

Creating equivalent flight test method
According to the chief rocket engineer, the zero one space OS-X series commercial rocket is a special flight test platform tailored for aerospace technology verification. The series rocket has successfully provided two commercial services for a certain Institute of AVIC. This launch mainly completed the key technologies of Linglong series launch vehicle, a new space payload and its equivalent flight test Two major test tasks are verification.
Among them, a new space load equivalent flight test method realizes the small angle equivalent trajectory. Through the near ground trajectory equivalent assessment of a space flight process, it innovatively realizes a high effective and low-cost full system full profile full equivalent test verification solution.
The launch achieved Intelligent Flight and intelligent control, which not only obtained a large number of real flight environment data, but also achieved complete success in both test missions.
Realizing multiple innovations of private rocket launching
(picture of rocket launch)
1. “Five ones” launch without support
Os-x6b intelligent rocket innovatively adopts vehicle launch technology, independently builds ground mobile telemetry station and launch station, and realizes “five one” launch of private rocket for the first time, namely “one rocket, one vehicle, one station, one machine and one pad”. With one rocket, one launch vehicle, one ground station, one UAV and one pad, the rocket launch task can be completed, and the rapid launch within 10 minutes can be realized.
2. Autonomous remote control mode launch
The os-x6b intelligent rocket independently built command and control network and visual system, and for the first time realized the independent remote control mode launch of private rocket. The intelligent rocket measurement and control center was set up in the intelligent rocket factory located in Liangjiang Aerospace Industrial Park for remote measurement and control and real-time monitoring. By receiving real-time telemetry data for driving, the virtual visualization of flight scene is realized synchronously, and the flight state of rocket and payload is displayed realistically.
3. Realization of rocket wireless intelligent measurement and launch control
The os-x6b intelligent rocket innovatively adopts high bandwidth and high reliability remote control and telemetry technology. For the first time, it adopts the rocket wireless measurement, launch and control mode to realize no front-end launch. At the same time, it adopts the “one button measurement and launch” mode to realize 100% intelligent interpretation of parameters and greatly shorten the launch preparation time.
4. The first exploration of human in the loop and other space vehicle control
The launch also reached the highest altitude of 300km in suborbital flight of private Rocket Company, thus meeting the technical verification conditions of orbital spacecraft. Therefore, this launch is the first time to explore the man in the loop control technology of spacecraft, as well as the upper stage redundant error tolerant control design technology.
5. First exploration of controlled reentry flight
The launch is also the first time for a private Rocket Company to explore controllable reentry flight and obtain a large number of reentry flight environment data.
6. 3D printing of attitude control power system products for the first time
Os-x6b rocket attitude control engine adopts integrated miniaturization of attitude control power system integration technology and 3D printing technology of complex structure. It uses new technology to realize highly integrated design of attitude control engine, greatly reducing product size and quality, which is only one third of traditional products. It is one of the key technology trends of new space load in the next five years.
Building an intelligent rocket
(rocket launch chart)
The os-x6b rocket is not only equipped with intelligent “brain”, but also has “intelligent nerve center” and many other innovative technologies. The rocket innovatively adopts intelligent test and automatic interpretation technology. Before launch, the rocket can automatically execute the test process and intelligently interpret the test results. The rocket also boldly cancels the front-end equipment of rocket test, launch and control, adopts wireless communication mode, and a pad can control the rocket launch.
The mission adopts remote test launch control technology and builds command and control network independently. The command and test personnel in Chongqing can implement one click test and launch for os-x6b rocket launch mission in Northwest China, greatly reducing preparation time and improving launch mission efficiency.
The rocket also innovatively uses real-time data-driven and animation demonstration technology to build a visual system. By receiving telemetry data of flight test trajectory and attitude, it drives the simulation model in real time, and displays the actual flight state and effect of the rocket realistically through animation.
(visual simulation picture)
The rocket explores the man in the loop control technology of spacecraft, and sends control commands to the rocket through the rocket ground wireless communication link to control its flight. The fault-tolerant control design technology of upper stage is explored, and the highly reliable attitude control algorithm design technology is adopted, which can make the mission load quickly identify and adaptively adjust the algorithm after one of the attitude control engines fails, and still maintain reliable and stable flight.
Fast response, launch in 10 minutes
(mobile launch map)
This launch is the first time for commercial aerospace enterprises to adopt the mobile rapid launch technology of the integration of rocket and vehicle. Through the mobile launch of the rocket launch vehicle and the change of direction after launch, the rocket does not need to go through the complex preparation and test work of the transfer and lifting of the launch site to the launch site. At the same time, the innovative use of high bandwidth and high reliability remote control and telemetry technology, the first time to take the rocket wireless measurement launch control mode, launch vehicle and command vehicle do not need to connect the cable. Innovative use of intelligent testing and automatic interpretation technology, the rocket can automatically execute the test process before launch, and intelligent interpretation of test results, to achieve “one click launch”. It takes only 10 minutes to prepare for launch. A tennis court size launch area can be launched, which greatly improves the launch efficiency.
This launch is also the fourth launch of the “Chongqing Liangjiang star” rocket independently developed by zero one space. Zero one space, founded in August 2015, is a leading rocket technology company in China. The company is committed to building an information-based, intelligent and practical “Rocket +” industrial service platform, and has developed three major technical fields of zero one rocket, zero one electronics and zero one power.
