Old and new technologies provide dynamic precise positioning
Vehicle's coordinates are available for both reporting and operator use utilizing passive survey techniques and equipments with excellent results thus freeing up and protecting the vehicle reporting transmitters. Use of spread spectrum radiolocation offers real-time extraction and correction of system biases eliminating fixed timing errors. An unlimited number of users may receive differential signals as well as system description data in such a manner as to facilitate complete ''blind'' entry into the system while attaining full operational capability. Utilizing a proprietary technique, the passive user obtains additional lines of position as well as calibration information while using the traditional number of reference stations. A single frequency could be used world-wide since ''networks'' are identified by code. Adjacent networks can be indicated to the receiver using the system description data thus facilitating network to network operation without operator intervention. Although the system accuracy is excellent for survey, the automation of dynamic precise positioning is most advantageous in vehicle location.
