Abstract

A method and apparatus for determining a heading, H, of an object, the method comprising the steps of: measuring (S1) carrier signal phases (Õ k , Õ m ) of satellite carrier signals, SCS, received from a number, N, of visible satellites on at least two antennas (A k , A m ) attached to said object and defining a baseline vector ( b ) of said object with a predetermined baseline length; calculating (S2) for each satellite carrier signal, SCS, a carrier phase difference ( Æ k m 1 , Æ k m 2 ¦ Æ k m N ) between the measured carrier signal phases (Õ k , Õ m ) of the satellite carrier signal, SCS, received on the at least two antennas (A k , A m ); calculating (S3) projection curves (PC1, PC2,...PCN) of the baseline vector ( b ) onto object satellite unit vectors (e 1 , e 2 ,...e N ) for all visible satellites when rotating said baseline vector ( b ) within a predetermined azimuth angle range, AAR; and comparing (S4) extracted fractional parts of the calculated projection curves (PC1, PC2,...PCN) with extracted fractional parts of their corresponding fractional carrier phase differences ( Æ k m 1 , ( Æ k m 1 , to identify a common intersection for all visible satellites representing the heading, H, of said object.
