Abstract:

Regarding to the popular meal ordering Apps in the market, we have developed a meal ordering system aiming at optimizing the current ordering platform through the Beidou Navigation Satellite System(BDS). The system realizes localization and achieves data transmission through installing GPRS and BDS orientation modules with messages shown on the Android client side in phones and data processing of the server side. In this system, route planning and navigation can be more easily to achieve through a series of procedures, transmitting positioning information of the Beidou Navigation Satellite System to server through GPRS, implementing functions of real-time positioning, SMS reminders and rest-time recording through data processing, as well as showing results on the client side. Apart from this, what makes the system faster and more efficient is the use of A* arithmetic to plan paths.
