Chinese satellite photographs commercial Maxar satellite

In what appears to be a tit-for-tat competition, a Chinese reconnaissance satellite, dubbed Jilin-1, has now taken photographs of a commercial Earth imaging satellite owned by Maxar, that the company had previously used to photograph other Chinese satellites.

Chinese commercial remote sensing constellation operator Changguang Satellite Technology (CGST), a spinoff from an arm of the state-owned Chinese Academy of Sciences, published images Sept. 13 of a Maxar Worldview Legion 2 satellite.

The images were taken by CGST’s Jilin-1 remote sensing constellation satellites across a few hours on Sept. 8, from ranges between 40-55 kilometers, showing details of the spacecraft. While part of an expanding Earth observation constellation, Jilin-1 satellites have apparently had their operations adjusted to include Non-Earth Imaging (NEI).

Maxar had earlier published high resolution images of China’s Shijan-26 satellite, being used to test remote sensing and surveillance technologies.

None of this is particular new, though for China the technology is the most advanced it has ever had. Nations have been launching high resolution surveillance satellites since the 1960s. Nor is there anything anyone can do about it. Nations will always do this. If anything, having this ability to observe each other closely will likely reduce tensions and misunderstandings.

Russian inspector satellite now approaching its eleventh communications satellite

A Russian inspector satellite dubbed Luch-2 and launched in March 2023 is now maneuvering to make a close approach and surveillance of an eleventh commercial communications satellite in geosynchronous orbit.

The company is forecasting that Luch 2’s next object of interest is the Intelsat 1002 communications satellite. “Luch 2 is expected to perform an additional maneuver to stop its drift near Intelsat 1002 on June 28 if it continues its past pattern of behavior,” Slingshot said. This behavior mirrors that of its predecessor, Luch Olymp-K-1, which has been known for similar intelligence-gathering activities.

The close approaches have ranged from 12 miles to 142 miles, with most getting inside 100 miles distance.

It is unlikely Russia is testing robotic maneuvering technology, as it has had this capability since the 1970s. More likely it is testing the ability to intercept communications from such satellites, though it is unknown whether Luch-2 has done so. Visiting multiple satellites would also permit it to test against a wide variety of technology.

US, Germany developing secret spy satellites

According to Wikileaks cables, the United States and Germany plan to develop a secret constellation of spy satellites. Though Germany denies the story, their denial is somewhat puzzling:

German Aerospace Center spokesman Andreas Schuetz said that such a project for a high-resolution optical satellite has been in discussion for the past two years under the name HIROS. “HIROS is neither a spy satellite, nor a secret project,” Schuetz said. He insisted that the project was to be used only for government purposes, “for example crisis management during natural catastrophes and for scientific uses.”

He refused to give any further details, saying the plan was still in the project stage and could not be discussed.
