Reference satellite selection method for GNSS high-precision relative positioning
Geodesy and Geodynamics, 2017 Selecting the optimal reference satellite is an important component of high-precision relative positioning because the reference satellite directly influences the strength of the normal equation.

Temporal variations in female moose responses to roads and logging in the absence of wolves. [PDF]
Ecol EvolWe characterized temporal changes in moose habitat selection and space use patterns near a road network in a wolf‐free area located in eastern Canada. Our results reaffirmed the year‐round aversive effect of roads, even in the absence of wolves, but the magnitude of this avoidance differed between day phases, being lower during the “dusk‐night‐dawn ...

Wildlife Monographs, Volume 213, Issue 1, November 2023., 2023 We developed a spatialized surface for the primary food of grizzly bears in southeast British Columbia. After using this huckleberry patch layer to model habitat selection, fitness, and density, in a bottom‐up top‐down paradigm, we found that huckleberry patches near forestry roads contribute very little to fitness and density.

Sensor Position Estimation Method for IoT Using Mobile Reference Node
IEEE Access, 2020 The paper proposes an innovative method of locating objects for the Internet of Things (IoT). The proposed method allows the position of a fixed measuring sensor (MS) to be estimated using one mobile base station with a known position moving around the ...
