An Integrated GNSS-Microcontroller-GSM System for Various Application Developments

摘要

Global Navigation Satellite System (GNSS) is used to obtain user's position, velocity and time (PVT) information. A scheme of using a low-cost, single-frequency multi-constellation GNSS hardware has been proposed here which can be used for several applications. The realization of the concept utilizes output data from a GNSS module in National Marine Electronics Association (NMEA) format that may be used by microcontroller and auxiliary hardware for location tracking, time synchronization or stamping and atmospheric monitoring purposes. The use of multi-GNSS is expected to provide enhanced capability of the generic system.
