This paper introduces the Compartmentalized Covariance Intersection (CCI) algorithm, a consistent technique to fuse measurements in cooperative navigation networks. The algorithm reduces the excess conservatism of standard Covariance Intersection (CI

This paper develops a coverage-centric adaptive path planner to visually survey a planar environment. This is achieved by modifying an existing path planning architecture to use a novel coverage estimation approach called convolved coverage estimatio

This paper demonstrates a method for improving the calculation of coverage during a seabed survey mission. Called convolved coverage estimation (CCE), this method can provide the pilot with coverage information in real-time. CCE gives a conservative

Mesobot, an autonomous underwater vehicle, addresses specific unmet needs for observing and sampling a variety of phenomena in the ocean's midwaters. The midwater hosts a vast biomass, has a role in regulating climate, and may soon be exploited comme

An online attitude determination filter is developed for a nano satellite that has no onboard attitude sensors or gyros. Specifically, the attitude of NASA Ames Research Center's O/OREOS, a passively magnetically stabilized 3U CubeSat, is determined

This paper presents a method for mapping translating, rotating icebergs with an autonomous underwater vehicle (AUV). To map an iceberg, the AUV first circumnavigates it, collecting multibeam sonar ranges and iceberg-relative Doppler sonar velocities

The attitude determination capability of a nano satellite is limited by a lack of traditional high performance attitude sensors, a result of having small budgets for mass and power. Attitude determination can still be performed on a nano satellite wi
