Xi'an CasTianta Co's self-developed data-processing software played a critical role throughout the Long March 12B carrier rocket's maiden flight at Dongfeng commercial space innovation pilot zone, which marked the launch of the Qianfan Constellation network satellite.

This rocket, a reusable model with a four-meter diameter, features a two-stage structure powered by liquid oxygen and kerosene and boasts a low-Earth-orbit payload capacity of over 20 metric tons. The project of the rocket had a 21-month development cycle. This launch marks the 647th mission in the Long March rocket series.

CasTianta specializes in aerospace telemetry and control software, satellite-borne hardware, and laser communication products, with full-chain data processing and R&D capabilities for rockets and satellites.

During the ground testing phase, the software collected rocket parameters and completed system verification. After the rocket's launch, it received real-time telemetry data to monitor flight attitude and engine performance. Working with the rocket's onboard flight control and high-speed bus systems, the software met the mission's extensive data-processing demands.

CasTianta plans to deepen its collaboration within the industrial chain by upgrading its telemetry and control software and expanding its capabilities in rocket management and on-orbit satellite operations.
