Provided is a centralized positioning method and a system for the old going outside. The centralized positioning method and the system for the old going outside comprise the following steps: (1) The locator calls the server or sends messages to ask for positioning. (2) After the server receives the location requests and checks the password, the server sends positioning instructions to the localization machine to be positioned by messages. (3) After receiving the positioning instructions, the localization machine starts the global position system (GPS) module to carry out the positioning and to output the GPS information. (4) The GPS information extraction module of the localization machine extracts the useful latitude and longitude information from the GPS information. The successfully extracted information is sent to the server by text messages according to the agreed format. (5) The server carries out the match with the position information and gets the specific information then tells the locators so as to achieve the positioning for the old. The centralized positioning method and system for the old going outside has the advantages that when you want to know the position of the old, the purpose can be achieved by sending messages to the server or making a call.
