PROBLEM TO BE SOLVED: To accomplish parallel generation of attitude by delivering an attitude correction and rate correction signals containing a line bias correction signal to an updating means for combining them with an LOS signal and obtaining the pitch, roll, yaw and the attitude rate using concurrent parallel line bias estimation values. SOLUTION: A receiving RF signal is delivered to a hard limiter 30 and converted into an IF signal. It is delivered to 9 channel in order to generate a difference phase measurementΔϕij and a rateδϕ*ij being inputted to a least square fit. These measurementsΔϕij,δϕ*ij are inputted from an input 31 to an attitude solution unit 32 which receives a base line vector, a line bias input 33 and an integer correction input 35. One feedback output 37 is fed through a line bias estimator 34 to an adder 40 while other is fed thereto through an integer estimator 36 and an integrity check unit 38. The attitude solution unit 32 produces the pitch, roll, yaw and the attitude rate according to an algorithm in response to the inputs at 31, 33 and 35.
