Real‐time and dynamic time transfer method based on double‐differenced real‐time kinematic mode

IET Radar, Sonar & Navigation, 2021
In this study, a real‐time and dynamic time transfer method based on double‐differenced (DD) real‐time kinematic (RTK) mode is proposed. First, the method forms the DD observations of Global Navigation Satellite System (GNSS) to fix the DD ambiguity, and

Real-time kinematic positioning with GPS and GLONASS [PDF]

2016 24th European Signal Processing Conference (EUSIPCO), 2016
Recently, low-cost dual constellation receivers with simultaneous tracking of GPS and GLONASS satellites and raw carrier phase output have become available. This enables a faster and more reliable ambiguity fixing especially in areas with limited satellite visibility, e.g. street canyons. In this paper, we present a combined GPS/GLONASS RTK positioning

Practical kinematics for real-time implementation of continuum robots [PDF]

Proceedings 2006 IEEE International Conference on Robotics and Automation, 2006. ICRA 2006., 2006
This paper introduces new analyses and algorithms which are essential for the practical implementation of continuous backbone continuum robots. Actuator length limits strongly shape the configuration or joint space of continuum manipulators, introducing couplings which are not reflected in previously published kinematic models.

Asynchronous RTK Method for Detecting the Stability of the Reference Station in GNSS Deformation Monitoring

Sensors, 2020
The real-time kinematic (RTK) positioning technique of global navigation satellite systems (GNSS) has been widely used for deformation monitoring in the past several decades. The RTK technique can provide relative displacements in a local reference frame

An In-Vehicle Smartphone RTK/DR Positioning Method Combined with OSM Road Network

Remote Sensing, 2023
In vehicle navigation scenarios, the RTK positioning results of smartphones are prone to jumps due to the interference of complex urban environments, and the heading angle of dead reckoning (DR) is prone to divergence.

Real-Time Inverse Kinematics Techniques for Anthropomorphic Limbs [PDF]

Graphical Models, 2000
In this paper we develop a set of inverse kinematics algorithms suitable for an anthropomorphic arm or leg. We use a combination of analytical and numerical methods to solve generalized inverse kinematics problems including position, orientation, and aiming constraints.

Antenna Array-Aided Real-Time Kinematic Using Moving Base Stations

IEEE Access, 2022
A global navigation satellite systems (GNSS) real-time kinematic (RTK) using multiple base stations is referred as an antenna array-aided RTK. This positioning method more reliably resolves carrier phase integer ambiguities by processing additional ...

Comparison of the real-time precise orbit determination for LEO between kinematic and reduced-dynamic modes. [PDF]

, 2021
The real-time high-accuracy orbit and clock of the GNSS (Global Navigation Satellite System) are one of the most essential corrections for the real-time kinematic precise orbit determination (POD) mode and reduced-dynamic POD mode for Low Earth Orbit ...

Harvester Evaluation Using Real-Time Kinematic GNSS and Hiring Service Model

AgriEngineering, 2021
To reduce human drudgery and the risk of labor shortages in the Asian developing countries, the appropriate introduction of agricultural machinery, especially combine harvesters, is an urgent task. Custom hiring services (CHSs) are expected to contribute
