Hello,
Arcording to the request of Mr. Fang Peng, I have updated the Wuhan's sitelog, mostly in the section 4.3 and 4.4.
By the way, the new granite pillar was set up in January 2002, and the dome on the GPS antenna came after 3 months later. But during that time and up to now, the type of the GPS antenna has not been changed. I hope every thing  important in the sitelog is listed in detail.
Please see attached for the updated sitelog and a photo of the dome.
Thanks, especially to Mr. Fang Peng.
Ms. Tu.
