Verfahren und Vorrichtung zum Verwalten einer Status/Alarm-Nachricht eines GPS-Empfängers und zum Senden einer Systemzeit

摘要

Apparatus and methods for managing a detailed status message and alarm message of a global positioning system (GPS) receiver and broadcasting an accurate system time. The GPS receiver receives current time and positional information from a global positioning system satellite, to generate clocks to respective blocks in a base station and to generate self status and alarm message data and system time message data. A base station control processor receives the status and alarm message data and system time message data, and separates the system time therefrom to immediately broadcast the system time to processors of the base station. The base station control processor also periodically checks for a change of the status and alarm message in the system time message data to report the change of the status and alarm message to a base station control device.
