An Integration of GPS with INS Sensors for Precise Long-Baseline Kinematic Positioning
Integrating the precise GPS carrier phases and INS sensor technologies is a methodology that has been applied indispensably in those application fields requiring accurate and reliable position, velocity, and attitude information. However, conventional integration approaches with a single GPS reference station may not fulfil the demanding performance requirements, especially in the position comp...
متن کاملKinematic Positioning with an Integrated GPS/Pseudolite/INS
Although existing integrated GPS/INS systems can overcome inherent drawbacks of each system, such as no result without line-of-sight for GPS and INS errors that grow with time, performance is nevertheless degraded in difficult operational circumstances. Some typical examples are when the duration of satellite signal blockage is excessive, resulting in large accumulated INS errors that are not a...
متن کاملIntegration of GPS Precise Point Positioning and MEMS-Based INS Using Unscented Particle Filter
Integration of Global Positioning System (GPS) and Inertial Navigation System (INS) integrated system involves nonlinear motion state and measurement models. However, the extended Kalman filter (EKF) is commonly used as the estimation filter, which might lead to solution divergence. This is usually encountered during GPS outages, when low-cost micro-electro-mechanical sensors (MEMS) inertial se...
متن کاملGPS/INS Integration for Vehicle Navigation based on INS Error Analysis in Kalman Filtering
The Global Positioning System (GPS) and an Inertial Navigation System (INS) are two basic navigation systems. Due to their complementary characters in many aspects, a GPS/INS integrated navigation system has been a hot research topic in the recent decade. The Micro Electrical Mechanical Sensors (MEMS) successfully solved the problems of price, size and weight with the traditional INS. Therefore...
متن کاملINS/GPS Integration Architectures
An inertial navigation system (INS) exhibits relatively low noise from second to second, but tends to drift over time. Typical aircraft inertial navigation errors grow at rates between 1 and 10 nmi/h (1.8 to 18 km/h) of operation. In contrast, Global Positioning System (GPS) errors are relatively noisy from second to second, but exhibit no long-term drift. Using both of these systems is superio...
