The Changchun Observatory has been tracking the CZ-2C rocket bodies for a whole year, using the normal picosecond KHz laser, along with normal ILRS missions, but with TLE prediction. The Graz people also has found reflective CZ R/B(s) earlier this year, but we are not sure how they are progressing.
We are planning to track other R/B's, of which the number is huge. So we need you to join up.
Below is the list of R/B target already tracked by SLR. Newly joining stations shall try with them.
========================
TLE# First tracked by
----------------------------------
28480 Changchun7237
31114 Changchun7237
38253 Graz7839
========================
Based on our space debris tracking campaign in 2014, below is other R/Bs that would hopefully carry reflector(s). But we haven't tried them.
========================
TLE# , Intl.Designater , Object Type

25400 1998-043G SL-16 R/B
22220 1992-076B SL-16 R/B
12988 1981-117B SL-14 R/B

Hi,
Dear Zhipeng,
Borowiec tracks regulary (since January 1, 2017) two CZ2C targets, 28480 and 31114. They give us very interesting results.
Kind regards,
Pawel

I am very happy to hear that. And I have good news that Changchun's historical data about these two targets are now disclosed. You can access them with the following FTP server:
IP address: [210.72.87.239]
user: laserspinrb password: Pa55w0rd_2017 access: read only
For now both targets' normal point data till April 2017 are online. For fullrate data, I still have problem in preserving multiple reflection patterns. Any help is welcome.
The access is now read-only. May make it read-write access or even move to sddis, if people are interested.

Dear Zhipeng,
what is the per pulse energy of the laser you used for the tracking of the rocket bodies?
Thanks and best

Hi Sven,
It's our normal SLR laser, with 1mJ pulse energy and 1kHz repetition rate, making 1W laser power. I think other high rate station could do it as well or better.
