The current Chinese localization

#Principia_MapNode_Periapsis = 近地点
#Principia_MapNode_Apoapsis = 远地点

in fact translates the terms as 'apogee'/'perigee'. AFAIK the correct translations should be '近拱点' and '远拱点', respectively.

AFAIK the correct translations should be '进拱点'

Surely that should be 近拱点?

This should also be reflected in the following two strings from the orbit analyser.

#Principia_OrbitAnalyser_Elements_ArgumentOfPeriapsis = 近地点幅角
#Principia_OrbitAnalyser_Elements_MeanPeriapsisAltitude = 平均近地点高度

近拱点幅角 is attested.

Ah, apologies. Typo'd.

平均近拱点高度 (mean periapsis altitude) does not appear in Google search results, whereas the current 平均近地点高度 (mean perigee altitude) does, but 近拱点高度 (periapsis altitude) is attested, so this seems like a reasonable extrapolation.

Further, a full-text CNKI search for 平均近拱点高度 with the Precise setting finds one result, namely 火星重力场模型发展回顾及对萤火一号的展望—On the Mars Gravity Field Models and Prospects of "Yinhuo-1" Mission, CNKI ID TWJZ201202007.
I was able to find a PDF, unfortunately it uses some stupid encoding so a text search does not work.
The phrase 平均近拱点高度 appears in the table at the top of page 223, which reads

主要阶段 时间范围 轨道特征
轨道刹车阶段 (AB1) 19971107-199803028 在近拱点高度约为 120 km 处的轨道周期从 35.4 h 降到 11.5 h,平均近拱点高度约 120 km,远拱点高度从 45 000 km 降到 18000 km。

So it seems that 平均近拱点高度 is sensible as a technical term/phrase, albeit rare.
