Summary
The CENTISPACE-1 S7 satellite, also known as Weili Kongjian 01-01, is a part of the Centispace-1 LEO constellation, designed to enhance global navigation services through GNSS augmentation signals. Launched on January 13, 2025, from Yellow Sea Launch Area LP4 using the Jielong-3 launch vehicle, it successfully entered its designated orbit and began operations three hours post-launch. The satellite, manufactured by DFH Shenzhen, has a WN-100 bus configuration and is powered by two deployable solar arrays and batteries. It features a laser communication link for data transmission at 2259.68 MHz frequency and operates with a silver-colored aluminum alloy structure shaped as a box equipped with two solar panels. With dimensions of 1 meter in length, 0.5 meters in diameter, and a span of 2 meters, it has a dry mass of 160 kilograms and is designed for a mission duration of approximately five years. It employs three-axis stabilization and has an RCS value of 0.3 with a VMAG of 6.5. This satellite is part of a constellation that includes CENTISPACE-1 S8, S9, and S10, and aims to significantly improve navigation services globally.
