Abstract

It is proposed a determination device, a method for determining navigation information and a navigation device comprising: a receiving circuit configured to receive a first signal from a first navigation satellite, the first signal comprising a first timestamp; a determination circuit configured to determine a velocity of the first navigation satellite at the first timestamp in a second coordinate system based on ephemeris data of the first navigation satellite, the second coordinate system being tilted in relation to the equatorial plane; the determination circuit further configured to determine a velocity of the first navigation satellite in a first coordinate system that is earth fixed and rotating with earth, by applying a transformation matrix to the determined velocity of the first navigation satellite in the second coordinate system and adding a correction term based on a time derivative of the transformation matrix; a navigation circuit configured to determine navigation information of the receiving circuit within the first coordinate system based on at least the determined velocity of at least the first navigation satellite.
