InertialConnect is the latest software solution for MicroStrain inertial sensors. With InertialConnect, you can easily configure your sensors, adjust parameters, upgrade firmware, and deploy preconfigured parameter files. You can also verify sensor outputs with intuitive visualizations, including times eries data, position data, and statuses.
InertialConnect is compatible with both PC desktop and Linux operating systems, making it your go-to solution for precision and efficiency in inertial sensor management.
SensorConnect is the next generation in desktop sensing software.
From configuration of nodes and starting networks, to collecting and analyzing data in real-time, SensorConnect provides a modern, powerful experience with our Wireless, Inertial, and Displacement products.
Using our intelligent data collection and graphing algorithms, you are able to visualize massive amounts of data instantly, and then zoom in on points of interest just as fast.
Built in MathEngine functionality allows for both real-time and post-processed math, such as generating FFTs, averages, RMS, etc.
SensorCloud is a unique sensor data storage, visualization, and remote management platform that leverages powerful Cloud computing technologies to provide excellent data scalability, rapid visualization, and user programmable analysis.
MicroStrain sensors can instantly upload their data to SensorCloud via an ethernet-connected WSDA-2000. Once uploaded, your data is securely stored in the Cloud and can be accessed from anywhere, or downloaded for offline use.
Configurable alerts can be set to help notify you of real-time event in your data.
MathEngine allows you to perform analytics on your data, all in the Cloud. Pre-built functions are available for ease of use, while IPython Notebooks allow advanced users to write custom scripts to be run on their data once, or on a schedule.
The MicroStrain Communication Library (MSCL) is our open-sourced API that simplifies writing code to interact with our sensors. MIP SDK is a lightweight C/C++ library for interacting with MicroStrain G and C-series products via baremetal and resource constrained microcontrollers.
Both APIs are readily available and fully-documented on GitHub, featuring valuable tools such as full documentation, example code, and a quick start guide.
Robot Operating System (ROS) is an open-source, meta-operating system for your robot. It provides the services you would expect from an operating system, including hardware abstraction, low-level device control, implementation of commonly-used functionality, message-passing between processes, and package management. ROS can be used in building and simulating robotics applications, as well as unmanned ground vehicles and simultaneous localization and mapping (SLAM). MicroStrain has an open source License free (MIT License) series of drivers specifically designed and tested for ROS.
The 3DM-GV7-AHRS is an Attitude and Heading Reference System (AHRS) that combines an Inertial Measurement Unit (IMU), a magnetometer, and advanced sensor fusion algorithms. It provides tactical-grade performance for measuring orientation (pitch, roll, yaw), angular rates, and linear acceleration in an environmentally protected IP68 package.
The 3DM-GV7-AHRS is an Attitude and Heading Reference System that includes magnetometer-aided heading, while the 3DM-GV7-AR is an Attitude Reference system (also called a VRU - Vertical Reference Unit) that provides high-accuracy orientation data without magnetic heading reference.
The 3DM-GV7-AHRS features an Auto-Adaptive Extended Kalman Filter designed specifically for consistent performance in challenging environments, individual calibration for optimal accuracy, cutting-edge orientation algorithms, advanced time management, and flexible event triggering systems - all in an ultra-compact ruggedized IP68 tactical-grade package.
