A radio surveillance team at a Chinese satellite launch centre have said they have found a jamming device that can interfere with navigation systems in a car outside the base – the first time it has reported such an incident.

Staff at the Jiuquan Satellite Launch Centre in Inner Mongolia found the item in a car ahead of the launch of the Shenzhou 14 mission

The jammer could cause a rocket to go off-course, but the space centre did not say whether the discovery was a sabotage attempt or an accident.

The device in question is a small frequency transmitter that can send an interference signal with a typical range of less than 10 metres.

If it's a commercial device, the jamming power should be limited, but obviously, the staff was still able to detect it.

If its only effective at <10m then I would say it was an accident and a commercial device.
Anything more than 50-100m and you could say it is deliberate

Anyway, good job to the staff who found it

The Advanced Space-Based Solar Observatory (ASO-S) satellite is scheduled to be launched in October this year. The ASO-S is China's first comprehensive solar observation satellite. One of the three major payloads, the Lyman Alpha Solar Telescope (LST) is mainly used to observe the formation and early evolution of coronal mass ejections.

【谷神星一号四级发动机成功开展2107秒长程高模试车】近日，星河动力空间科技有限公司完成了四级轨控发动机的2107秒超长程高模试车，试验取得圆满成功。高模试车目的是考核真空环境下高空喷管的结构与性能，验证发动机真空点火、稳态工作、多次点火、关机的性能，是确保飞行试验时发动机的安全性和可靠性的重要验证手段

The private launch company Galactic Energy/Galaxy Power Space Technology has successfully completed a 2107-second test run of its four-stage orbital control/maneuvering engine(?). The purpose of the test run was to evaluate the structure and performance of the high-altitude nozzle in a vacuum environment and to verify the engine's vacuum ignition, steady-state operation, multiple ignition, and shutdown performance.

Its a diagram showing the orbit inclinations of various earth observation satellites (for example FY-2G is designated as a meteorology satellite). The string of 5 satellites with the yellow orbit line are likely geostationary/geosynchronous satellites that remain stationary over east asia since they follow a near equatorial orbit. The other 3 are in highly inclined polar orbits, so they are likely in sun synchronous orbits and are always imaging the ground that's illuminated by the sun.
