Abstract
A GPS navigation receiver with a data output port for communicating a position estimate frame-by-frame and time codes in SMPTE format. The conventional date and time sentence output of the GPS navigation receiver is combined with a highly-accurate one pulse-per-second (.+-.one microsecond) to form a time-keeping base for the time code output. A data-logger records the position estimates with their corresponding time in time code format frame-by-frame in a database. The recorded position estimates are then used in special-effects post-production to direct the special-effects animation, modeling kinetics, etc., in a composite, final film or video.
