GPS/IMU Integrated System for Land Vehicle Navigation based on MEMS
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. Both advantages and disadvantages of each individual system are analyzed. The Micro Electrical Mechanical Sensors (MEMS) successfully solved ...
متن کاملA Kalman filtering approach for Integrating MEMS-based INS and GPS for land vehicle applications
Global Positioning System (GPS) and Inertial Navigation Systems (INS) are used for positioning and attitude determination in a wide range of applications. Since the usage of high performance INS is limited by its high cost, for general application areas low-cost INS units are used. Over the last few years, a number of low-cost inertial sensors have become available. However, these low cost sens...
متن کاملUsing Land-vehicle Steering Constraint to Improve the Heading Estimation of Mems Gps/ins Georeferencing Systems
The integrated navigation systems of Global Positioning Systems (GPS) and Inertial Navigation Systems (INS) are used to provide direct-georeferencing for Mobile Mapping Systems (MMS). MEMS (Micro Electro-Mechanical Systems) inertial sensors have been developed to the stage that the GPS/INS integration systems based on low-cost MEMS IMU (Inertial Measurement Unit) are considered to be used as a ...
متن کاملA Performance Improvement Method for Low-Cost Land Vehicle GPS/MEMS-INS Attitude Determination
Global positioning system (GPS) technology is well suited for attitude determination. However, in land vehicle application, low-cost single frequency GPS receivers which have low measurement quality are often used, and external factors such as multipath and low satellite visibility in the densely built-up urban environment further degrade the quality of the GPS measurements. Due to the low-qual...
متن کاملThe Aiding of MEMS INS/GPS Integration Using Artificial Intelligence for Land Vehicle Navigation
This paper applies two Artificial Intelligence (AI) techniques, fuzzy logic and expert system, to enhance the Kalman filter-based MEMS INS/GPS integration. For better INS error control, the expert knowledge on vehicle dynamics is utilized to simplify dynamics models and to extend measurement update schemes in the velocity filter. To optimize position fusion, a fuzzy inference system is develope...
