Geolocation worldwide?

i am currently developing a application for world wide usage. Currently i am having some geolocation issues in china.

Does the ionic native geolocation + cordova geolocation plugin work worldwide? or do they require some plugin for glonass and beidou? (from my searches the plugins for cordova beidou are inactive for more than 3 years) And if yes does ionic native or cordova geolocation make automatic correction to the coordinate system used by different geolocation systems?
