In 2025, Ziwei Technology plans to launch four spacecraftIn 2025, set off again! Ziwei Technology plans to launch four spacecraft in July, September and November.July: Planned launch of B300-L02September: Planned launch of B300-L03 and B300-F01November: Planned launch of B300-L04Di Er IV (B300-L02) is the orbit-retaining version of Ziwei Technology (AZPACE)'s self-developed B300 series products, scheduled to be launched in July 2025.The spacecraft consists of a service module and a payload module, with a cargo capacity of 300kg and a cargo space of 1.2m³. It adopts a three-axis ground-stabilized flight attitude for a long time in orbit, with an attitude control accuracy of 0.05° and an attitude stability of 0.005°/s. The DIER-4 intelligent cargo compartment management system can effectively meet the experimental environment and customization requirements for payload temperature, voltage, radiation measurement, etc., with small restrictions on payload; it provides payload control, status monitoring, on-orbit operation management, business data collection, storage, download, reception and other services, and can also be customized according to customer needs.
There is already a thread for this.
Breaking News! AZSPACE has only 40kg of payload left for its first flight in 2025 | Starship is ready to go, invite you to join us2025 launch plan:August 2025: B300-L02 orbital version
[Model Dynamics] Development Progress | AZSPACE Dier-5 (B300-L02) service module completes final assembly and integrationRecently, the B300-L02 small cargo spacecraft, which Ziwei Technology expects to launch in August, has completed the assembly and integration of the service module.The B300-L02 spacecraft consists of a service module, a payload module, and a cone section (rendezvous and docking section), and the service module that has completed the assembly and integration this time consists of a power subsystem, a comprehensive control subsystem, an attitude control subsystem, a propulsion subsystem, and a communication subsystem; it provides a stable energy supply and power transmission for the spacecraft, meets precise navigation control and orbital maneuvers, and also ensures the safety of the spacecraft's stable operation in orbit.The completion of the assembly and integration of the B300-L02 service module is a key link in the development of the B300-L02, which has accelerated the model development of the B300-L02 and laid the foundation for the subsequent launch and operation of the B300-L02.
Why has the thread been renamed from Dier 4 to Dier 5? The first post says B300-L02 is Dier 4.

[Model News] AZSPACE's B300-L02 payload cabin integration and testing has officially startedRecently, the final assembly, integration and testing of the payload cabin of Ziwei Technology's Di'er No. 5 (B300-L02) small cargo spacecraft has officially started, marking the key stage of the development of the spacecraft and laying the foundation for the launch mission scheduled for August this year.The Di'er No. 5 (B300-L02) spacecraft consists of a service cabin, a payload cabin, and a cone section (rendezvous and docking section). Its payload cabin is equipped with an intelligent cargo cabin management system and can accommodate 100 payloads working simultaneously in orbit, supporting microgravity experiments, new technology verification, space exploration, space biology, space planting, mini space laboratories and creative devices, etc. At the same time, it can provide professional and systematic one-stop payload customization services according to customer needs.
Di Er No. 5, "departure"!On the shore of Taihu Lake, a new journey to the skyAt 4:30 pm on June 22, in the Ziwei Science and Technology Park in Liangxi District, Wuxi City, the gate of the Ziwei Technology Spacecraft Intelligent Manufacturing Base slowly opened, and the Di Er No. 5 (B300-L02) space test vehicle officially appeared at the departure ceremony, announcing that its space journey has entered the countdown.This spacecraft, carrying 34 cutting-edge scientific experimental payloads and a total of 300 kilograms of cargo, will board the China Aerospace Science and Industry Corporation's Kuaizhou series carrier rocket in August this year, piercing the sky and exploring the mysteries of the universe.On the same day, the summary and review meeting of the Di Er No. 5 (B300-L02) spacecraft assembly and test phase was held. The review team composed of experts and leaders in the aerospace field carefully reviewed the "Summary Report of the Assembly and Test Phase of the Di Er No. 5 Space Test Vehicle".The experts at the meeting agreed that the final assembly and integration status of the service module, payload module and cone section (rendezvous and docking section) of the B300-L02 small cargo spacecraft is clear, and all technical indicators and performance meet the design requirements, so the next step can be carried out accordingly.B300-L02 is the orbital version of the B300 series small cargo spacecraft independently developed by Ziwei Technology. Its intelligent cargo compartment management system can meet the simultaneous operation of 100 payloads on orbit, and supports related space test tasks such as microgravity experiments, new technology verification, space exploration, space biology, space planting, mini space laboratories and creative devices. It can also provide customers with professional and systematic one-stop payload customization services.After the review meeting, under the witness of the experts and leaders present, AZSPACE signed a cooperation agreement with Wuxi Zhongwei Yixin Co., Ltd., Wuxi Yuanqing Tianmu Biotechnology Co., Ltd., Tianyi Space Biotechnology (Wuxi) Co., Ltd., Earth Pulse (Wuxi) Technology Co., Ltd., Jiangyin Bio-Intelligent Biotechnology Co., Ltd., and Hunan Zhongke Changle Technology Business Service Co., Ltd. to jointly cooperate in space application fields such as chip testing, space mutagenesis breeding, space organoid experiments, biopharmaceuticals, and digital transmission.The vigorous development of Ziwei Technologyis a vivid epitome of the strong rise of Liangxi District's aerospace industryLiangxi's precise policytailor-made "Major Project Service List"Injecting strong momentum into aerospace enterprisesLast year, it also successfully won the onlypilot for the development of aerospace future industry clusters in Jiangsu ProvinceZiwei Science and Technology Park has also become a bridge connecting cutting-edge technology and public science popularization. The specially designed visiting corridor in the base allows visitors to witness the shocking process of spacecraft assembly at close range; in the supporting exhibition hall, the real engine and real return capsule, as well as agricultural exhibits such as "corn and rice" that have experienced space travel, continue to inspire young people's dreams of space travel.In February this year, the base was officially listed as the "Liangxi Aerospace Industry Youth Science Education Base", becoming a new business card for science and technology education in Wuxi.
