Any info on the launch site of the OS-X rocket?

From the video, it appear, that the trajectory of the OS-X launch (red) was lower than planned (blue).

Yes, it looks like the planned peak altitude was 40 km, with actual being about 37 km. There also seemed to be a large deviation in the Z axis at 200 km downrange.

Article about the launch:

Note: given the graphs above, it seems that altitude and downrange distance are mixed up in the article.

From Xinhua:
"The nine-meter-long, 7,200-kg rocket has a maximum altitude of 38.742 kilometers and a top speed of more than 5.7 times the speed of sound, according to Shu Chang, founder and CEO of OneSpace."

The article mentions "launch center in northwest China" and "manufacturing base in southwest China's Chongqing Municipality"

China has successfully developed and tested its first hypersonic experimental waverider vehicle. After separating from a carrier rocket, #StarrySky2, which rides its own shock waves, maintained ultrafast speeds above Mach 5.5 for 400+ seconds and reached Mach 6 (7,344 km/h).

XK-2 was launched very likely from as the same location as OS-X on May 17th, i.e. from the sounding rocket range near the Alxa airport (see https://forum.nasaspaceflight.com/index.php?topic=43696.40). I found some footage from a XK-2 launch video which helps to localize the position of the launch pad and the camera.
Another open question is who operates this rocket range. Maybe it is under administration of the Jiuquan Satellite Launch Center which supports launches from Alxa with its tracking and control facilities. Another option is that the rocket range belongs to the Huayin Ordnance Test Center (the former Base 32) which operates  a large distance weapon test range north of Alxa.

IHS Janes community thinks both because the Alxa site (multiple now airports use that name in the province) used to be home silos.
