Ultra Low-Power, Lightweight, Probabilistic RSS-Based Path Reconstruction: A System for Landscape-Scale Bee Tracking

Read the original on arXiv Machine Learning →

The paper presents a new RSS‑based localization system that tracks ultra‑light, low‑power receivers across complex landscapes. By using a minimal number of RSS measurements from rotating high‑gain transmitters and probabilistic modeling, the system achieves about 15 m accuracy for 38 mg receivers over a 300 m range while consuming less than 180 µW. Increasing RSS measurements improves accuracy to roughly 10 m at under 600 µW, and the method is demonstrated on tracking Bombus terrestris nest return flights.

Camera Calibration Using Inaccurate and Asynchronous Discrete GPS Trajectory from Drones

The paper tackles the problem of calibrating a stationary camera’s yaw, pitch, and roll using a drone’s GPS trajectory, which suffers from altitude bias, time offset, and discrete sampling. It formulates a parameter estimation problem that jointly estimates the GPS altitude bias, time offset, and camera orientation biases, and proposes a maximum likelihood estimator based on Iterated Least Squares to handle the asynchronous, discrete GPS data. Simulation results show the estimator achieves accuracy close to the Cramér–Rao Lower Bound, with a recommended drone trajectory yielding calibration errors within 14% of the measurement error standard deviation.
