GPS modernization provides a foundation for developing multi-frequency a ttitude determination receiver.To satisfy the attitude determination requiremen ts of platforms such as low orbit satellites,missiles,aircrafts and naval vess els,a general design scheme for multi-frequency attitude determination receive r is given,which is composed of antenna unit,measurement unit and attitude comp utation unit.Then,some key technologies are investigated,including real-time cycle slip detection and correction based on GPS multi-frequency combination no i se residual,and the ambiguity resolution algorithm for single epoch using geome try restriction.The computation equations and flows are described in detail.Fi nally,a static test is carried out for the GPS-based single frequency receiver and multi-frequency receiver for attitude determination.The test results indic a te that,as for the attitude determination accuracy and computation success rati o,the multi-frequency receiver shows better performance than that of the singl e-frequency receiver.
