Getting Started

The following video is a quick intro to the EvalTool for Windows. For other applications scroll below.

1. Installing Software

Inertial Sense software provides a way to view, manipulate, stream, and record the data generated by a µINS, µAHRS, or µIMU.

EvalTool (Windows Only)

The EvalTool is a graphical Windows-based desktop program that allows users to explore and test functionality of the Inertial Sense products in real-time.

Download the EvalTool installer from the Inertial Sense releases page. Run the .exe file and follow the instructions to complete the installation.

CLTool (Windows, Linux, and OS X)

The CLTool is a command line utility that can be used to read and display data, update firmware, and log data from Inertial Sense products.

CLTool must be compiled from our source code. Follow the instructions on the CLTool page.

SDK (Windows, Linux)

Software development kit to interface with Inertial Sense products.

Download the file named "Source code" from our releases page. The extracted folder contains code libraries as well as example projects.

2. Connecting Your Hardware

Select the evaluation product from the list below to view instructions on basic connection to a computer.

3. Configuring Settings

The configuration settings found in DID_FLASH_CONFIG need to be set to appropriate values using either the EvalTool, the CLTool, or the SDK. A full explanation can be found on the System Configuration page. Most users initially configure the unit using the EvalTool. This is done by going to the Data Sets Tab and selecting DID_FLASH_CONFIG. The values of each field can then be edited. Pay special attention to the following fields:

  1. gps1AntOffset[X-Z] - Position offset of sensor frame with respect to GPS1 antenna.

  2. gps2AntOffset[X-Z] - Position offset of sensor frame with respect to GPS2 antenna.

  3. insDynModel - Dynamic model that most closely represents sensor application.*

    *Note - This feature is experimental. For most applications setting 8 will yield the best results. The user is encouraged to try different settings.

4. Evaluation and Testing

Once a connection to the unit has been established, please follow one of the following guides to get started with the software tool of choice:
