From now on, the MEMS based heading reference systems are in the race of size and cost and they have very much stabilized. Needless to say, the 3D accelerometers are high-performance applications which are originally developed with the certain room of further improvements. The MEMS gyroscopes have been adopted the most exciting applications and devices of MEMS. Time is changing at a rapid rate and iPhone and other consumer electronic goods have started adopting the most advanced 3D gyroscopes. However, the automotive and industry standard gyroscopes have no competition with ordinary “consumer grade” gyros used in mobile devices. When it comes to navigation and 3D motion sensing, there are a lot of performance and quality differences. MEMS Gyros The bias stability of MEMS Gyros also needs improvements in certain parameters with its initial bias. The parameters are navigation and functionality of AHRS systems. The gyros used in automobiles were designed mainly for working in ESP systems in which the short term bias stability possesses more value than bias stability of long term. On the other side, stabilization, controlling and navigation of applications are the leading requirements of performances of the gyro bias stability. The long term bias is now on the way of improvements over the automotive MEMS gyros of past decade. The new “industrial grade” bias is now under generation by the inertial MEMS makers. In this segment of MEMS gyros, the inertial MEMS manufacturers are working in production line of Fiber Optic Gyros (FOG). Now, we are going to see a major future of all AHRS major components such as accelerometers, magnetometers, gyroscopes and processors. Although integrated hardware equipments are designed and manufactured due to today’s increasing demand, there are some applications capable to utilize these equipments in proper way. The best thing is user-friendliness and convenience of these exciting products. Today the three most popular segments of motion capture are entertainment for special effects in the movies and game developers, movement science for clinical, sports and rehabilitation and various industrial applications. Measurement and correlation, control and stabilization and the navigation are three most contributing fields. For the essential requirements of performance, the accelerometer, magnetometers and gyroscopes are needed with a specific grade. In the industrial AHRS systems, all types of requirements of applications can be fulfilled especially when it comes to include the most advanced complementary sensors which use fusion algorithms and these applications include LIDAR, optical devices, barometers, GPS, magnetometers, sonar, and laser scanners. The applications of human motion tracking are also used in professional areas like healthcare, medical, filmmaking and gaming development. And the high performance gyroscopes are used in military applications and customers pay higher for improved performance. Bottom Line In the near future to come, the “Consumer grade” accelerometer devices will be upgraded with higher performances and capabilities. The today’s Sony Move, iPhone 4 and Nintendo Wii are the next generation of high tech future gadgets which use MEMS accelerations. Now, the high-end antenna systems and aerial cameras and various unmanned machines use this technology. Visit inertiallabs.com to know more about heading reference systems.
