Big on Small Things

ROV Operation from a Small Boat

Remotely operated vehicles (ROVs) are useful tools for aquatic research, but are underutilized because of the high operational costs and limited versatility of older models. Scientifically useful ROVs were originally very expensive to purchase or lease, and costly to operate with limited models available. With an increase in the number of models available and lower operating costs, the use of R...

Detecting a Small Boat using Histogram PMHT

The conventional tracking paradigm is to sequentially apply a single frame detector to each sensor frame and then employ a tracking algorithm to determine which detector outputs originate from targets and which are false alarms. The tracker associates detections from a particular target and estimates parameters of interest for the target [3], [1]. The obvious shortcoming of this approach is tha...

Accessing the Solar System With a Small Solar Sail

Solar sailing is a proposed means of space propulsion in which a reflective surface collects momentum from solar photons to accelerate a vehicle. The current trend within the solar sailing community is to increase sail size as solar sailing technologies advance, allowing for larger payloads and higher accelerations. However, with the miniaturization of modern payloads, sail sizes can be dramati...
