Abstract

The purpose of absolute sensor alignment is to determine the measurement and attitude biases of a sensor in an absolute reference frame. It has been well-documented that the performance of composite tracking with multiple sensors can severely degrade if the sensor measurements are not corrected for the bias. There are well-established metrics to assess the performance of tracking techniques and quantify the effects of other functions on the tracking process. However, there is a lack of metrics to assess sensor alignment techniques apart from other functions. The purpose of this paper is to present metrics for absolute sensor alignment techniques that assess performance apart from other functions. An absolute sensor alignment technique is presented and simulation results are employed to illustrate the alignment metrics.
