【长三乙成功发射天链二号02星】12月14日零时09分，长征三号乙运载火箭在我国西昌卫星发射中心点火升空，成功将天链二号02星送入预定轨道，发射任务取得圆满成功。这是长征系列火箭发射从400次迈向500次的第一步。
天链二号02星由中国航天科技集团有限公司五院研制，是我国第二代地球同步轨道数据中继卫星，主要用于为飞船、空间实验室、空间站等载人航天器提供数据中继和测控服务，为中、低轨道资源卫星提供数据中继和测控服务，为航天器发射提供测控支持。
本次发射是长征系列运载火箭的第401次发射。（中国航天科技集团）Quote from: translated by Google[Chang San B successfully launches Tian Lian 2 Satellite 02] At 0:09 on December 14th, the Long March 3 B carrier rocket ignited into the sky at my country's Xichang Satellite Launch Center, successfully sending Tian Lian 2 Satellite 02 into its intended orbit , The launch mission was a complete success. This is the first step in the Long March series of rocket launches from 400 to 500.
Tianlian-2 02 was developed by the Fifth Academy of China Aerospace Science and Technology Corporation. It is my country’s second-generation geosynchronous orbit data relay satellite. It is mainly used to provide data relay for manned spacecraft such as spacecraft, space laboratories, and space stations. And measurement and control services, provide data relay and measurement and control services for medium and low orbit resource satellites, and provide measurement and control support for spacecraft launches.
This launch is the 401st launch of the Long March series of carrier rockets. (China Aerospace Science and Technology Corporation)

2021-124A/50005 in 181 x 35825 km x 27.05° (S/C)
May I ask a initial question? where can I get such information? I tried https://nssdc.gsfc.nasa.gov/nmc/spacecraft/query,
2021-124B/50006 in 112 x 34336 km x 26.29° (3rd stage)
there is no the newest NSSDCA ID and orbit information.
By the way, what does 181 x 35825 km x 27.05° mean? low orbit, high orbit and degree?
is there any site or software can show such information in GUI?

These are parameters of elliptical orbit:
Perigee [km] x apogee [km] x inclination [deg]
further details:

https://en.wikipedia.org/wiki/Elliptic_orbit
Also, terms "Perigee" and "apogee" - they are specific for Earth-centered orbits (suffix "gee").
In general, these points are Periapsis & Apoapsis explained here:
