Orbit uncertainity
WebMar 28, 2024 · The GPS satellite orbit uncertainty estimates depicted in Figure 3 suggest a factor around 1/5000 from position to velocity for the random errors. In order to provide also some room for unmodeled systematic effects, the corresponding uncertainty estimates for velocity are conservatively computed with a conversion factor of 1/3000 from GNSS ...
