The PIGA is the oldest accelerometer and widely used in rocketry and guidance, and still the best – but MEMS-based devices are getting closer. The previous parts looked at the principle and operation of the PIGA. This part looks briefly at its history and refinement and the MEMS-based versions of the PIGA being developed and […]
Gyroscope
PIGAs can indeed fly – and are still the best, Part 2: Operation
The PIGA is the oldest accelerometer and widely used in rocketry and guidance, and still the best – but MEMS-based devices are getting closer. At the core of each single-axis PIGA is a gyroscope. The performance of this gyro – which is unrelated to the orientation gyros – plays a large role in determining the […]
PIGAs can indeed fly – and are still the best, Part 1: Frame of reference
The PIGA is the oldest accelerometer, is widely used in rocketry and guidance, and is still the best – but MEMS-based devices are getting closer. When you see an inexpensive drone, a more sophisticated one, an unmanned aircraft, a standard piloted aircraft, guided or intercontinental ballistic missile ICBM), an underwater drone or submarine, or a […]
What sensors are in a smart cane? Pt 2
Inspired by self-driving vehicles and robotics, the Augmented Cane developed by Stanford University researchers uses a LiDAR sensor to measure distance to nearby obstacles and then provide directions so blind or visually impaired users can navigate around those areas. Additional sensors in the research prototype include GPS, accelerometers, magnetometers and gyroscopes to monitor the user’s […]
Six-axis MEMS motion sensors features supreme vibration rejection, temperature stability
TDK Corporation announced the availability of the InvenSense ICM-45xxx SmartMotion ultra-high-performance (UHP) family of 6-axis MEMS motion sensors. This family introduces the on-chip self-calibration, industry’s lowest power consumption, and world’s first BalancedGyro™ (BG) technology. BalancedGyro technology by TDK is the first-of-its-kind gyroscope MEMS architecture that enables supreme vibration rejection and temperature stability performance, an enhancement […]
Three-axis gyroscope/accelerometer combo is automotive qualified
TDK Corporation announces the availability of InvenSense IAM-20680HT high temperature automotive monolithic 6-Axis MotionTracking sensor platform solution for non-safety automotive applications, which includes the IAM-20680HT IMU MEMS sensor and the DK-20680HT developer kit. The IAM-20680HT embeds a 3-axis gyroscope and a 3-axis accelerometer in a thin 3 x 3 x 0.75mm (16-pin LGA) package and […]
How can you improve the next-generation IMU?
At Sensors Expo 2019, Lou Thaddeo, the Director of Business Development for Thales Visionix Inc. discusses how Visionix’s newest NavChip Series 3 inertial measurement unit (IMU) plays a critical role in helmet mounted displays for pilot head tracking and other applications. The 6-axis (3-axis accelerometer and 3-axis gyroscope) IMU implements enhanced performance over NavChip Series […]
How can an RTC feature stabilize an image sensor’s output?
At Sensors Expo 2019 in San Jose, CA, Sahil Choudhary, a product marketing manager at InvenSense, demonstrates how the real-time clock (RTC) feature in his company’s 6-axis (accelerometer and gyroscope) sensors provides accuracy and stabilization for critical imaging applications. For a specific device frequency, say 10 Hz, the RTC input ensures that the 10 Hz […]
How can sensors make a smart ball?
At Sensor Expo 2018 in San Jose, CA, an expert from NXP Semiconductors describes the Internet of Things (IoT) smart ball demo that NXP had in its booth. Sensors in the ball provide real-time data and the system can publish the data to the cloud using IBM Bluemix Services. The data includes 3-axis measurements from […]
What’s new in IMUs?
At Sensors Expo 2018, Faheem Faheem, the Director of R&D for Visionix Engineering for Thales Visionix, discusses NavChip 2, a next-generation inertial measurement unit (IMU) with high sensitivity and high performance. Architected around proprietary technologies and advanced signal processing techniques, the IMU contains a microelectromechanical systems (MEMS) 3-axis accelerometer and 3-axis gyroscope for 6-axis motion sensing.
