Chapter 4 - GNSS Error Sources

In Chapter 2, we introduced the concept of GNSS error sources. These are the factors that make it difficult for a GNSS receiver to calculate an exact position. In this chapter, we will look more deeply into these error sources.

Contributing Source Error Range
Satellite Clocks ±2 m
Orbit Errors ±2.5 m
Inospheric Delays ±5 m
Tropospheric Delays ±0.5 m
Receiver Noise ±0.3 m
Multipath ±1 m
