Vector Field‐Based Collision‐Free Navigation in Tunnel‐Like Environments
Journal of Field Robotics, EarlyView.ABSTRACT Tunnel‐like environments, renowned for their vast scale, confined spaces, and limited visibility, present significant challenges for autonomous robot navigation. This study addresses the critical issue of guiding robots through such environments while ensuring collision‐free navigation and maintaining a specified safety margin from both tunnel

Application of GPS tracking techniques to orbit determination for TDRS [PDF]
In this paper, we evaluate two fundamentally different approaches to TDRS orbit determination utilizing Global Positioning System (GPS) technology and GPS-related techniques. In the first, a GPS flight receiver is deployed on the TDRSS spacecraft.

River Research and Applications, EarlyView.ABSTRACT Globally, there has been an increase in the development and use of hydropower to produce energy. Hydropeaking is an operating regime that is used to meet real‐time energy demands; however, daily fluctuations in flows may result in fish becoming stranded.

GPS Multipath Detection in the Frequency Domain
, 2016 Multipath is among the major sources of errors in precise positioning using GPS and continues to be extensively studied. Two Fast Fourier Transform (FFT)-based detectors are presented in this paper as GPS multipath detection techniques. The detectors are

Covariates influence optimal camera‐trap survey design for occupancy modelling
Remote Sensing in Ecology and Conservation, EarlyView.We investigated the impact of covariates (e.g., habitat quality, temperature) on the optimal design of camera trap surveys to estimate species occupancy. Using simulations of a virtual species, we found that increasing the number of cameras consistently reduced error across a range of covariate effects.

Path Estimation from GPS Tracks
, 2007 The widespread availability of hand-held GPS units has led to a proliferation in data on the tracks of individuals as they walk, drive or otherwise go about journeys. This data has been used in a number of ways - for example the OpenStreetMap project (The OpenStreetMap Foundation 2007).

Remote Sensing in Ecology and Conservation, EarlyView.We combined arboreal camera trapping and non‐invasive genetic tagging to estimate group size in the critically endangered northern muriqui (Brachyteles hypoxanthus) in Brazil's Atlantic Forest. Both methods provided complementary insights into group size and demographic structure, while differing in their cost‐effectiveness and sampling constraints ...
