After searching for the mass of China's Guowang Internet-service satellites and finding nothing, I estimated it using ChatGPT. Since I knew the number of satellites (10) and the rocket used (Long March 5B) in two launches, the mass of a single satellite could be estimated if I knew the carrying capacity of the rocket.
I asked ChatGPT this question five times: How much mass could a Long March 5B rocket with a Yuanzheng-2 (YZ-2) upper stage carry to 1,100 kilometers with an inclination of 86.5 degrees?
As shown in this summary, the average capacity is 16.6 tonnes or 16,600 kg. The full answers can be found here.
I've shown the final answers here, but ChatGPT explains the seven or so intermediate steps it took to compute the final answer. Like the final results, they are different in each of the queries. It would be interesting if they could be recorded.
These five results are all different and seem to be independent of each other. ChatGPT does not remember prior submission of the same question
I am not a rocket scientist and can only average the five results in estimating the satellite masses. I'd like to know what experts think of the results and the intermediate steps taken in deriving them.
