Abstract:
1. A satellite navigation device for calculating a code pseudo range based on a navigation signal from a navigation satellite, comprising: a pseudo range correction module for correcting the code pseudo range that is smoothened based on a carrier phase, by performing an ionosphere delay correction with a code ionosphere delay, wherein the pseudo range correction module matches a direction of a carrier ionosphere delay contained in the carrier phase with a direction of the code ionosphere delay to correct the code pseudo range; and wherein the pseudo range correction module matches the direction of the carrier ionosphere delay contained in the carrier phase with the direction of the code ionosphere delay by matching a shifting direction of the carrier phase due to a first carrier ionosphere delay contained in the carrier phase used in the smoothing of the code pseudo range with a correction direction of a second carrier ionosphere delay for a carrier correction of the code ionosphere delay used in the ionosphere delay.
