99--TECHNOLOGY TRANSFER OPPORTUNITY MULTI-AXIS ACCELEROMETER CALIBRATIONSYSTEM USING A CUBOIDAL ATTITUDE POSITIONING DEVICE

NASA Langley Research Center in Hampton, VA solicits inquiries from companies interested in obtaining license rights to commercialize, manufacture and market the following technology. License rights may be issued on an exclusive or nonexclusive basis and may include specific fields of use. NASA provides no funding in conjunction with these potential licenses. THE TECHNOLOGY: Scientists at NASA Langley Research Center have developed a low-cost, portable, and simplified system suitable for in-situ calibration and/or evaluation of multi-axis inertial measurement instruments (e.g., accelerometers). This system overcomes facility restrictions and maintains or improves the calibration quality for users of accelerometer-based instruments with applications in avionics, experimental wind-tunnel research, and force balance calibration applications. This innovative calibration apparatus can quickly and easily position a multi-axis accelerometer system into a precisely known orientation suitable for in-situ quality checks and calibration. In addition, the system incorporates powerful and sophisticated statistical methods, known as response surface methodology, with statistical quality control and error detection. These methods improve calibration quality, reduce calibration time, and increase calibration frequency, which enables the monitoring of instrument stability over time. The cuboidal positioning system can be used to calibrate or evaluate single, dual, or tri-axial packages. The system allows for in-situ calibrations that are robust to operator error. It is mechanically simpler, one tenth the cost of traditional systems and more precise. The algorithm compensates for local gravitational constant and employs a simplified, linear mathematical model that is a function of gravitational components.
