You need to try and register with Space-Track to get the Two-Line Orbital Elements (TLEs).
https://www.space-track.org/auth/login

Then you write software or set up a spreadsheet that will take in TLEs and give you the orbital period and altitude.

fairing news:

1月9日上午11点50分,一块火箭整流罩落在宣恩县晓关侗族乡大山坪村姚家坪的烟田中,村民杨善红发现后及时向村委会报告。
杨善红介绍,当时他正在烟田干活。突然,空中传来轰轰的声响,一块形似小船的物件掉落在离他约500米的位置。记者在现场看到,该物件长约9米,宽约3.5米,呈半圆状,外形似小船,上面有固定支架。

I remember that in late October images from the Dongfanghong Ltd. AIT were released, depicting both Gaojing satellites together with a label, which indicates that the XY-5B satellite is in preparation simultaniously. This was the reason of speculations that a third satellite will be launched together with GJ-3/4. But either this launch of XY-5B was canceled or will happen later.
