A novel near field communication system for s-martphones based on visible light (NECAS) is presented in this paper. NECAS encodes information using combinations of different colors (red, green and blue) and their intensity levels of a smartphone screen, while the receiver captures the light signal via color sensors. In our scheme, a smartphone screen is segmented into four sub-blocks, and each of...
In order to resolve the carrier phase ambiguity in attitude determination, a new approach is proposed and discussed. A method for static baseline vector estimation is derivate based on the epoch-difference carrier phase and a receiver clock bias model. By using the estimated baseline vector, a float solution of ambiguity is computed. The range of potential integer ambiguity can be obtained with the...
