List of Navigational Satellite Constellations

Basics

• This Page Lists All of the Various Navigational Satellite Constellations in order to organize their pages, and to make selection of systems easier for projects

Global

• These can be used anywhere on earth, although they may still favor zones for coverage

GPS

• The Original, Worldwide, yet some regions require additional networks to receive proper coverage (See Regional Neteworks) (USA Owned and operated)
• GPS

GLONASS

• Russian Owned and Operarted (Provides better coverage of Area Near the earth's poles, but lesser accuracy overall)
• GLONASS

Galileo

• EU owned and operated
• May be more accurate the GPS but has similar coverage
• Newer so some issues associatesd to it being new (there was an outage for a while in 2019)

BDNSS

• China Owned and Operated
• In a sort of transition between regional coverage to worldwide
• Public Accuracy is a Few Meters (2.5-3 depending on if in Asia, or Elsewhere respectively
• Military has an encrypted cm level channel (Similar to early GPS before the public was allowed accuracy)
• BDNSS

Regional

• These allow for regional use (typically the country that owns it, or a local effort by countries that use it) or higher accuracy and/or covarage for existing systems such as GPS, in the latter case this is a method of GNSS Enhancement

IRNSS

• Indian Regional System
• May expand into a worldwide system as the GINS
• IRNSS

QZSS

• Japan's Regional System
• As of now, no plans to expand into a worldwide system (Most likely due to standing with USA as an ally and thus no need to be independant from a potentially tactial system)
• QZSS
