A strengthened signal Optimal Algorithm with Adaptive Orthogonal Jammer Constraint (OAAOJC) is proposed

which can be used in the anti-jamming of the the Navigation Receivers of Two Satellites.This algorithm eliminates the jammers and receives two satellite signals through determining the Orthogonal Jammer Subspace(OJS) and the quiescent weight vector(the weight vector under the condition of no jammers) and projecting the quiescent weight vector onto OJS.To calculate the quiescent weight vector

the strengthened signal optimal algorithm with equal SNR is presented

which can make the CRPA with small diameter from two beams in directions of the two satellites in condition of no jammer.In order to obtain OJS

the MUSIC algorithm is introduced and the threshold which is used to distinguish the jammer subspace and OJS is given through analyzing the effect of the sampling number and the CRPA 's inconsistency on the perturbation of the minimum eigenvalue.This algorithm is characterized by stable voltage output

microsecond level update ratio of the weight vector and large jammer-eliminating-ratio with certain gains for satellite signals.
