Abstract

Inertial sensors have been employed in different types of applications in miniature embedded devices such as phones, watches, and small unmanned aerial vehicles. The stochastic structure of the error signal coming from these sensors is complex and needs to be determined for optimal fusion with other devices (e.g. GPS). The recently-proposed approach, Generalized Method of Wavelet Moments (GMWM) using the wavelet variance (WV), overcomes these limitations. The presented software platform can be used for stochastic calibration (i.e. parameter determination) of IMUs or other types of sensors. The software is Open Source and is developed within the broadly used statistical framework R using C++ language.

Free software

Free software or libre software or libreware is computer software distributed under terms that allow users to run the software for any purpose as well as to study, change, and distribute it and any adapted versions. Free software is a matter of liberty, not price; all users are legally free to do what they want with their copies of a free software (including profiting from them) regardless of how much is paid to obtain the program.

Open-source software

Open-source software (OSS) is computer software that is released under a license in which the copyright holder grants users the rights to use, study, change, and distribute the software and its source code to anyone and for any purpose. Open-source software may be developed in a collaborative, public manner. Open-source software is a prominent example of open collaboration, meaning any capable user is able to participate online in development, making the number of possible contributors indefinite.

Wavelet

A wavelet is a wave-like oscillation with an amplitude that begins at zero, increases or decreases, and then returns to zero one or more times. Wavelets are termed a "brief oscillation". A taxonomy of wavelets has been established, based on the number and direction of its pulses. Wavelets are imbued with specific properties that make them useful for signal processing. For example, a wavelet could be created to have a frequency of Middle C and a short duration of roughly one tenth of a second.
