565 results about "Real Time Kinematic" patented technology

Real-time kinematic (RTK) positioning is a satellite navigation technique used to enhance the precision of position data derived from satellite-based positioning systems (global navigation satellite systems, GNSS) such as GPS, GLONASS, Galileo, and BeiDou. It uses measurements of the phase of the signal's carrier wave in addition to the information content of the signal and relies on a single reference station or interpolated virtual station to provide real-time corrections, providing up to centimetre-level accuracy. With reference to GPS in particular, the system is commonly referred to as carrier-phase enhancement, or CPGPS. It has applications in land survey, hydrographic survey, and in unmanned aerial vehicle navigation.

Method for representing real-time motion

A system 100 for tracking the movement of multiple objects within a predefined area using a continuation of overhead X-Y tracking cameras 24 with attached frequency selective filter 24f. Also employed are perspective Z filming cameras sets 30. Objects to be tracked, such as player 17, have been marked to include some form of frequency selective reflective material such as an ink. Typical markers include patches 7r and 7l, sticker 9 and tape 4a as well as additional body joint markers 17af through 17l. System 100 radiates selected energy 23a throughout the predefined area of tracking that is specifically chosen to reflect off said reflective materials used to mark for instance player 17. The reflected energy is then received by tracking cameras 24 while all other ambient light is blocked by filter 24f. Local Computer System 60 continuously captures images from said tracking cameras 24 which include only the minimum information created by said reflected energy. System 60 efficiently locates said markings on said multiple objects and uses this location information to determine for each marking its angle of rotation, angle of azimuth and distance from a designated origin 17o local to player 17. Local origin 17o is then expressed as a three-dimensional coordinate with respect to the origin of the playing venue 2a. The continuous stream of tracked three-dimensional coordinates, defining the body joints on players such as 17, is then transmitted to a remote computer where it can be used to drive a graphic re-animation of the object movement. Along with this re-animation, additional performance measurements may be derived from the continuous stream and automatically made available in real-time.
