Early life movements and mortality of Egyptian vultures: Implications for transcontinental conservation. [PDF]
Ecol EvolWe used data from 32 Egyptian vultures (Neophron percnopterus) tagged with GPS transmitters as nestlings in three Iberian breeding areas to study their dependence period, migration routes, movements in Africa, and mortality at each stage. Our results show no significant differences in the timing of nest departure or the duration of the dependence ...

Flight results of GPS‐based attitude determination for the Canadian CASSIOPE satellite
NAVIGATION, Volume 67, Issue 1, Page 83-93, Spring 2020., 2020 Abstract The paper presents attitude determination results of the “GPS Attitude, Positioning and Profiling Experiment” (GAP) on board the CASSIOPE satellite using real flight data. The GAP payload consists of five minimally modified commercial‐off‐the‐shelf NovAtel OEM4‐G2L receivers that provide dual‐frequency GPS measurements and allow for attitude ...

Evaluation on Nonholonomic Constraints and Rauch–Tung–Striebel Filter‐Enhanced UWB/INS Integration
Mathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020 Precise and seamless positioning is becoming a basic requirement for the Internet of Things (IoT). However, there is a gap for precise positioning in Global Navigation Satellite System‐ (GNSS‐) denied indoor areas. Thus, a multisensor integration system based on ultrawide‐band (UWB), inertial navigation system (INS), nonholonomic constraints (NHCs ...

Journal of Sensors, Volume 2020, Issue 1, 2020., 2020 Global Navigation Satellite System Real‐Time Kinematic (GNSS‐RTK) technology is widely used in vehicle navigation, but in complex environments such as urban high‐rise street, wooded street, overpass, and tunnel, satellite signals are prone to attenuation or even unavailability. It brings great challenges to the continuous high‐precision navigation. For

Mathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020 Ultrawideband (UWB) is considered as a promising technology in indoor positioning due to its accurate time resolution and good penetration through objects. Since the functional model of UWB positioning is nonlinear, iterative algorithms are often considered for solving the nonlinear problem.

Fine‐scale spatial risk models to predict avian collisions with power lines
Journal of Applied Ecology, Volume 62, Issue 8, Page 1820-1830, August 2025.Our study illustrates a framework for using bird movement data to provide insights into avian behaviour and the risk they encounter around power line infrastructure. Electricity delivery industries can use these models to identify the electrical infrastructure that poses the highest risk to avian survival and prioritise mitigation efforts, thereby ...

Reliability Analysis of Network Real‐Time Kinematic
Journal of Electrical and Computer Engineering, Volume 2018, Issue 1, 2018., 2018 The multistate reliability theory was applied to the network real‐time kinematic (NRTK) data processing chain, where the qualities of the network corrections, baseline residuals, and the associated variance‐covariance matrices are considered as the system state vectors.

Is GPS telemetry location error screening beneficial?
Wildlife Biology, Volume 2017, Issue 1, Page 1-7, January 2017., 2017 The accuracy of global positioning system (GPS) locations obtained from study animals tagged with GPS monitoring devices has been a concern as to the degree it influences assessments of movement patterns, space use, and resource selection estimates. Many methods have been proposed for screening data to retain the most accurate positions for analysis ...
