RTK-EVC: Real-Time Kinematic Positioning With Enhanced Velocity Constraints Via Factor Graph Optimization in GNSS-Challenged Environments

Abstract: In this paper, we propose a novel Real-Time Kinematic positioning architecture with Enhanced Velocity Constraints (RTK-EVC) which is solved by factor graph optimization. The RTK procedure ...

Speed-time and velocity-time graphs

A negative gradient shows the rate of “slowing down” or deceleration. Velocity-time graphs show velocity on the vertical axis. Acceleration is still represented by the gradient. Key fact The gradient ...

Revise: Motion - equations and graphs

The gradient of a displacement-time graph at a particular time gives the velocity of the object at that time. The gradient of a velocity-time graph at a particular time gives the acceleration of the ...
