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 Networks) (USA Owned and operated)
- GPS
GLONASS
- Russian Owned and Operated (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 associated 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
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
