Autonomous navigation of micro-UAVs is typically based on the integration of low cost
Global Navigation Satellite System (GNSS) receivers and Micro-Electro-Mechanical …

This article is adapted from my Brouwer lecture of February 2001 [1]. It has been shortened
by about one quarter and updated. Given the occasion (in 2001) I had thought it …

This paper presents a cooperative navigation technique which exploits relative vision-based
sensing and carrier-phase differential GPS (CDGPS) among antennas embarked on …

The different TRIAD algorithms are considered as specializations of the generalized TRIAD
algorithm developed here. The attitude matrix estimate, error and covariance are developed …

An off-line smoother algorithm is proposed to estimate foot motion using an inertial sensor
unit (three-axis gyroscopes and accelerometers) attached to a shoe. The smoother gives …

The TRIAD algorithm is shown to be derivable as a maximum-likelihood estimator. In
particular, using the QUEST measurement model, the TRIAD attitude error covariance matrix …

Present-day systems for human movement analysis are not portable, have a limited capture
volume and require a trained technician to analyze the data. To extend the use and benefits …

The optimized TRIAD algorithm of Bar-Itzhack and Harman, proposed in 1997 on the basis
of insupportable premises, is shown to provide, nonetheless, the optimal solution of the …

Many current and future aerial and space missions are based on the paradigm of distributing
the tasks among several platforms to overcome the limits of the single vehicle. This thesis …
