摘要: : Integration of GPS with inertial sensors can provide many benefits for navigation, from improved accuracy to increased reliability. The extent such benefits, however, is typically a function the quality system used. Traditionally, high-cost, navigation-grade measurement units (IMUs) have been used obtain highest position and velocity accuracies. However, work documented in this paper uses Honeywell HG-1700 IMU (1 deg/h) assess tactical-grade aiding high-accuracy (centimeter-level) applications. To end, integrated during complete partial data outages investigated. benefit using improve ambiguity resolution process after also addressed detail. Centralized decentralized filtering strategies are compared terms performance.
