Honeybee navigation [PDF]

open access: yesCurrent Biology, 2003
Why the interest in honeybees? Many of us have marvelled at the ability of honeybees to find an attractive flower patch, miles away from their hive, and to return to it repeatedly with unerring accuracy. How do they do this with a brain smaller than a sesame seed? We don't know all the answers yet, but bees seem to be able to estimate the distance to a

A Navigation Ranging Scheme With True Random Entangled Microwave Signals

open access: yesIEEE Photonics Journal, 2018
Focusing on the problem of vulnerable anti-deception and weak anti-jamming ability in classical pseudorandom code correlation ranging, we present a navigation ranging scheme with true random entangled microwave signals.

Robust design of a machine learning-based GNSS NLOS detector with multi-frequency features

open access: yesFrontiers in Robotics and AI, 2023
The robust detection of GNSS non-line-of-sight (NLOS) signals is of vital importance for land- and close-to-land-based safe navigation applications. The usage of GNSS measurements affected by NLOS can lead to large unbounded positioning errors and loss ...

Geomagnetic/inertial navigation integrated matching navigation method

open access: yesHeliyon, 2022
The accuracy of an a priori geomagnetic reference map is a significant constraint on the geomagnetic matching navigation method. Especially when the aircraft enters an unknown environment, it is impossible to accomplish the navigation task using traditional geomagnetic navigation methods.
