Modelling and assessment of Galileo and Galileo/GPS velocity determination with stand-alone receiver

期刊: JOURNAL OF NAVIGATION, 2021; 74 (4)

Reasonable stochastic model and function model are the premise of accurate velocity determination, especially in the time-differenced carrier-phase (T......

Analysis of impact of group delay on slope distortion of S-curve in delay locked loop

期刊: JOURNAL OF NAVIGATION, 2021; 74 (3)

As essential specifications of correlation domain for signal quality evaluation, distortions of the S-curve, including bias and slope distortions of t......

Application of colour combinations on visual search tasks under vibration environments

期刊: JOURNAL OF NAVIGATION, 2021; 74 (2)

Colour is widely utilised as a visual coding system in visual search, but its application under vibration conditions (e.g., in various vehicles) has n......

Research on the hydrographic survey cycle for updating navigational charts

期刊: JOURNAL OF NAVIGATION, 2021; 74 (4)

Due to the vast ocean area and limited human and material resources, hydrographic survey must be carried out in a selective and well-planned way. Ther......

Stereo visual odometry with velocity constraint for ground vehicle applications

期刊: JOURNAL OF NAVIGATION, 2021; 74 (5)

This paper proposes a novel method of error mitigation for stereo visual odometry (VO) applied in land vehicles. A non-holonomic constraint (NHC), whi......

A bionic point-source polarisation sensor applied to underwater orientation

期刊: JOURNAL OF NAVIGATION, 2021; 74 (5)

With the characteristics of full autonomy and no accumulated errors, polarisation navigation shows tremendous prospects in underwater scenarios. In th......

A cross-cultural investigation of design and visual preference of signage information from Hong Kong and Pakistan

期刊: JOURNAL OF NAVIGATION, 2021; 74 (2)

Signage design has been considered critically important for wayfinding, being a functional medium of delivering environmental information. Complex ins......

A cost-effective beam forming structure for global navigation satellite system multipath mitigation and its assessment

期刊: JOURNAL OF NAVIGATION, 2021; 74 (2)

Array antenna beam forming has high potential to improve the performance of the global navigation satellite system (GNSS) in urban areas. However, the......

Recovering authentic global position system L1 signals under spoofing using dual receiver direct positioning

期刊: JOURNAL OF NAVIGATION, 2021; 74 (4)

Spoofing is a kind of deliberate interference that aims to manipulate global navigation satellite system (GNSS) receivers into counterfeit position so......

A new underwater positioning model based on average sound speed

期刊: JOURNAL OF NAVIGATION, 2021; 74 (5)

The layout of seafloor datum points is the key to constructing the seafloor geodetic datum network, and a reliable underwater positioning model is the......

A cellular automaton-based model of ship traffic flow in busy waterways

期刊: JOURNAL OF NAVIGATION, 2021; 74 (3)

In busy waterways, spatial-temporal discretisation, safe distance and collision avoidance timing are three of the core components of ship traffic flow......

Lie group based nonlinear state errors for MEMS-IMU/GNSS/magnetometer integrated navigation

期刊: JOURNAL OF NAVIGATION, 2021; 74 (4)

In the integrated navigation system using extended Kalman filter (EKF), the state error conventionally uses linear approximation to tackle the commonl......

Ship domain model for ships with restricted manoeuvrability in busy waters

期刊: JOURNAL OF NAVIGATION, 2021; 74 (3)

Ship domain is an important theory in ship collision avoidance and an effective collision detection method. First, several classical ship domain model......

Modelling liquefied natural gas ship traffic in port based on cellular automaton and multi-agent system

期刊: JOURNAL OF NAVIGATION, 2021; 74 (3)

Over the past few decades, the number of liquefied natural gas (LNG) ships and terminals has been increasing, playing an important role in global clea......

Exploring into contributing factors to young seafarer turnover: empirical evidence from China

期刊: JOURNAL OF NAVIGATION, 2021; 74 (4)

Various studies suggest that the maritime industry will continue to face the challenge of seafarer shortages. Young seafarer turnover has become a ser......
