Apparatus and Method for ultra-fast GNSS initial positioning scheme with peer assistance, and Recording medium thereof

摘要

The fastest GPS cold start device and method were introduced through peer support. Rapid GPS cold start device is a communication module for receiving the help information that is generated to reflect the frequency error of the distance and the other terminal to the slave device from the master device via the peer support in accordance with an embodiment of the present invention; Communicating signaling information to deliver information to require immediate assistance from the instant the receivable; GPS receiver to quickly search for a GPS satellite signal and continuously track the GPS satellite signal and extract the pseudo distance by utilizing the help information; Using the assistance information and the pseudo range and a calculation processor for calculating the position of the slave terminal. According to embodiments of the present invention, on the existing A-GPS technology faster than the initial position measurement is possible, and can be implemented only by the direct communication between the mobile communications network, regardless of whether or not the two GPS receivers have A-GPS is having areas or regions You can overcome many limitations. ;
