Web1 aug. 2024 · The Center for Orbit Determination in Europe (CODE) is contributing to the most recent reprocessing effort of the International GNSS Service (IGS) with a triple-system solution including GPS (since 1994), (since 2002) and Galileo (since 2013). WebThe IGS ACs have generally adopted specific and as realistic as possible attitude modeling to lower the effects of these errors (e.g., Kouba’sattitude laws, Dilssner’sestimated yaw rate from measurements,…). Still, we observe today noticeable differences in the clock estimates provided by the ACs during eclipses.
