It's ridiculous that the BeiDou constellation status is posted on the Glonass official website, while not on the official BeiDou webportal...
...CAS' Shanghai Micro-satellite Center... How many will the two build respectively, and of what type?

Do we actually know who's who for the production of the phase 3 (a.k.a. "global phase") satellites? It looks like that both CAST and CAS' Shanghai Micro-satellite Center are building satellites for the operational global system, with the two scheduled for launch this month coming from CAST and the two launching next month or so coming from CAS.How many will the two build respectively, and of what type?
Lei Fanpei said at the 19th National Congress, the BD3 system would reach IOC by the end of next year

Is there a source where these graphs can be found, or are they your own work?
The first two Medium Earth Orbit (MEO) satellites of the third generation of BeiDou satellite navigation System (BDS-3) were successfully launched on November 5, 2017. This historical launch starts the new era of the global navigation satellite system of BeiDou. Before the first two satellites of BDS-3, a demonstration system for BDS-3 with five satellites, including two Inclined Geosynchronous Orbit satellites (IGSO) and three MEO satellites, was established between 2015 and 2016 for testing the new payloads, new designed signals and new techniques. In the demonstration system, the new S frequency signal and satellite hydrogen clock as well as inter-satellite link (ISL) based on Ka-band signals with time-division multiple addresses (TDMA) were tested. This paper mainly analyzes the performances of the demonstration system, including the signal-to-noise ratios, pseudorange errors and the multipath errors of the civilian signals of BDS-3. The qualities of signals in space, time synchronization and timing precision were tested as well. Most of the performances were compared with those of the regional BeiDou satellite navigation system (BDS-2). At last, the performances of positioning, navigation and timing (PNT) of the future BeiDou global system (BDS-3) were evaluated based on the signal quality of the present demonstration satellite system.
