The Global Positioning System (GPS) has been approved for a limited number of applications in civil aviation because it is not highly available for meeting safety-of life levels of integrity, which require timely alert if the system is unreliable for navigation under the environment of Performance Based on Navigation (PBN). This paper presents an analysis about principle of an inertial navigation system (INS) and design an new mechanical architecture of INS in terms of increased availability of GPS for civil aviation. This new mechanical architecture has a good mechanical properties in mechanical engineering of civil aviation.
