Basics
- Any way of making SATNAV more accurate
Regional Scale
- This is done mainly using Navigational Satellite Constellations to fill in gaps others leave in certain areas, aims to increase accuracy to the standard level
- See List of Navigational Satellite Constellations
RTK
- This is useful for smaller scale applications such as Surveying and ROVs, aims to increase accuracy to cm or mm level
- See RTK
Redundancy
- This can be done by more than one receiver and checking for errors
- Also additional systems such as Loran can be used for redundancy
- Also techniques such as Dead Reckoning can be used for redundancy as well
