Combined Compass/Gyroscope/Accelerometer is self-calibrating.

Press Release Summary:

Featuring voltage supply filtering, Model 1056 PhidgetSpatial 3/3/3 includes 3-axis compass, continuously calibrated for changes in sensitivity, offset, and magnetic field; and 3-axis gyroscope calibrated for sensitivity to rotation and cross-axis misalignment. Three-axis, ±5 G accelerometer is calibrated for misalignment and sensitivity to positive and negative acceleration. System's board offers data rate from 4-1,000 msec/sample and operates from 4.75-5.25 Vdc via USB.

Self-Calibrating Compass/Gyroscope/Accelerometer

CALGARY, Alberta - Phidgets Inc. released today the 1056 - PhidgetSpatial 3/3/3 which combines a Compass 3-Axis, a Gyroscope 3-Axis and an Accelerometer 3-Axis 5G. "We have taken the time to rigorously test the product to ensure that it provides 'real life' data, instead of simply relying on the sensors' technical specifications." says Chester Fitchett, CEO of Phidgets. "We also use precise voltage supply filtering to guarantee low noise and correct sensor operation." added Chester. The Compass is continuously calibrated for changes in sensitivity and offset. Errors introduced by magnetic fields and distortion of the earth's magnetic field may be compensated out by using our calibration program to calculate the correction factors to feed the device. Each Gyroscope axis is calibrated for sensitivity to rotation and cross-axis mis-alignment. Each accelerometer axis is calibrated for cross-axis mis-alignment, sensitivity to positive and negative acceleration, and offset. Product Specifications

"Unlike a lot of our competitor's products that require their users to write some firmware code in order to use their sensor, we are completely "Plug and Play" says Bernard Rousseau, Director of Marketing. "With Phidgets, you plug it in and start using it and when it comes to programming, the user, not us, decides which operating system and which computer language he wants to use", added Rousseau. Users can program Phidgets using a simple yet powerful and well documented Application Programming Interface (API) that is supported under Windows (2000, XP, Vista), Windows CE, Mac OS X, and Linux. Users can write programs in Visual Basic, VB.NET, C#, C/C++, Flash/Flex, Java, Labview, Matlab, ActionScript 3.0, and Cocoa. Phidgets also provides programming examples for all its products to help programmers write their own programs. The API Libraries as well as the examples and the documentation are available at no charge on Pricing and Availability
The 1056 PhidgetSpatial 3/3/3 is available now. The suggested resale price is $150.00 Canadian. About Phidgets
