3801 A Low-cost INS/GPS Integrated Navigation System with General-Purpose Sensors
Details
INS/GPS integrated navigation systems, which have been widely used for aircrafts and spacecrafts, have great potential for widespread use. But they have never been used popularly because they use big, heavy and expensive dedicated components. Therefore this paper suggests a new INS/GPS configuration with general-purpose MEMS sensors and a GPS, which have poor precision for navigation, and quaternion algorithm. Making a prototype proves the suggested INS/GPS is far smaller, lighter and more inexpensive than existing ones. In addition, an experiment for comparing with GAIA, a high-precision INS/GPS instrument developed by JAXA, shows it gives precision enough for controlling or monitoring general moving objects.
