For many navigation applications, improved accuracyperformance is not necessarily the most important issue, but meeting performance at reduced cost and size is. In particular, small navigation sensor size allows the introduction of guidance, navigation, and control into applications previously considered out of reach e.g., artillery shells, guided bullets. Three major technologies have enabled advances in military and commercial capabilities Ring Laser Gyros, Fiber Optic Gyros, and Micro-Electro-Mechanical Systems MEMS gyros and accelerometers. RLGs and FOGs are now mature technologies, although there are still technology advances underway for FOGs. MEMS is still a very active development area. Technology developments in these fields are described with specific emphasis on MEMS sensor design and performance. Some aspects of performance drivers are mentioned as they relate to specific sensors. Finally, predictions are made of the future applications of the various sensor technologies.
