The IIM-20670 features a robust monolithic 6-axis IMU, 3-axis accelerometer, and 3-axis […]
Fault-tolerant 6-axis IMUs target industrial apps
TDK Corporation extends the SmartIndustrial line of robust and accurate motion sensors and announces the availability of InvenSense IIM-46234 and IIM-46230 new high-performance fault-tolerant inertial measurement units (IMU) targeted at navigation applications that require accurate, stable, and best-in-class bias instability at an affordable price. IIM-46234 and IIM-46230 are modules that include multiple 6-axis sensors, each […]
What sensors are used in AR/VR systems?
A wide range of sensor technologies is required to support augmented reality and virtual reality (AR/VR) systems. Today’s AR/VR implementations are mostly focused on visual and audio interfaces and rely on motion tracking and listening/voice recognition sensors. That’s beginning to change with new types of sensors and various types of haptics being introduced. This FAQ […]
How are sensors improving maritime navigation?
Of course, GPS is important, but radar and the automatic identification system (AIS) use various sensors to track and report on ship positions in real-time. Sensor fusion is being developed for autonomous shipping. And there are hydrophones combined with other sensors and artificial intelligence (AI) and machine learning (ML) to identify and track whale movements […]
What sensors do you need to land on the moon?
NASA is developing several sensor systems and algorithms for use on Artemis moon landings. It’s called the Safe and Precise Landing – Integrated Capabilities Evolution (SPLICE) technology suite. It consists of three primary elements: An inertial measurement unit (IMU) and a camera for terrain relative navigation. Second is Doppler LiDAR to determine the lander’s velocity […]
PIGAs can indeed fly – and are still the best, Part 3: History and future
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 […]
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 […]
