China News Service, Beijing, July 31 (Ma Shuaisha, Liu Jia) At 10:00 AM Beijing time on July 31, my country successfully launched Pakistan Remote Sensing Satellite 01 from the Xichang Satellite Launch Center using a Kuaizhou-1A carrier rocket. The satellite entered its planned orbit smoothly, marking a complete success. The satellite will be primarily used for land surveys and disaster prevention and mitigation

Bro the rocket is Kuaizhou-1A Pro not Kuaizhou-1A.

This is a direct translation  of the link to chinanews.com.  They just call it " 快舟一号甲 " (Kuaizhou yihao jia) and do not mention the Pro variant. That doesn't mean it's not, just that the official launch statement doesn't describe it as such.

Yeah, on Next Spaceflight and on Chinese Wikipedia they all called it Kuaizhou-1A not 1A pro. But bro both are different variant.  It just like soyuz Rocket. Like sometimes Soyuz-U Sometimes Soyuz-2.1b/1a, etc.

However, the photo in the ChinaNews article and the launch video clearly show, that it is a Kuaizho-1A-Pro version.
We can be sure, that this photo is from the current launch, as the only other flight before had different markings on the fairing.

Though this is a nre rocket (They planned to call it KZ-1B) different from original KZ-1A, they still call it KZ-1A in official becuase this can increase success rate！

There is no any "pro" both Chinese and English in photo...

I believe this fits with PRSS-2? Therefore collaboration with SAST?
PRSC-EO1 launched January was "indigenously built"

PRSC-S is likely also indigenously, PRSC-EO. I suspect, that PRSC-EO is the electro-optical component of PRSC (= Pakistan Remote Sensing Constellation ?) and PRSC-S is a SAR component. This is not confirmed yet.

I do not know, what the current status of PRSS 02 is, if it is an ongoing project or if it has been replaced by the PRSC constellation.

I have the same suspicion - a SAR sat to complement PRSC-EO1,
and an indigenous (as well as ingenious)  satellite.

After checking, IAMCAS/SECM claims the satellite.

At 10:00 a.m. Beijing time on July 31, 2025, my country successfully launched Pakistan's remote sensing satellite, 01, from the Xichang Satellite Launch Center using a Kuaizhou-1A carrier rocket. The satellite's solar panels deployed smoothly and functioned normally, concluding the launch mission was a complete success. The satellite will primarily be used for land surveys and disaster prevention and mitigation.


This mission marks the 70th satellite launch by the Institute of Microsatellite Innovation under the Chinese Academy of Sciences. To date, the Institute has successfully launched 184 satellites covering communications, navigation, remote sensing, science, and micro-nano fields.

This is the Kuaizhou 1A Pro (KZ-1A Pro) rocket. Look at the photo of all the launches and compare the body.
