Claim:
1. An earth positioning system, comprising: a plurality of fixed positioning landmarks with wireless communication functions, each of the positioning landmarks being configured to wirelessly transmit coordinates of longitude, latitude and altitude of the positioning landmark, wherein each said positioning landmark is an outdoor light, an indoor light or an electronic device; a mobile communication device configured to receive the coordinates of longitude, latitude and altitude and a received signal-strength indicator (RSSI) value or channel response of at least one of the positioning landmarks, wherein the plurality of positioning landmarks are arranged in an indoor environment or an outdoor environment, and when the mobile communication device moves along with a user, the mobile communication device obtains coordinates of longitude, latitude and altitude of the mobile communication device by constantly scanning the coordinates of longitude, latitude and altitude and the RSSI values or the channel responses of the positioning landmarks nearby and calculating the coordinates of the mobile communication device directly in the mobile communication device, wherein the coordinates of longitude, latitude and altitude of positioning landmarks written into the positioning landmarks by the mobile communication device are obtained previously from an outdoor map or an indoor map, and the outdoor map or the indoor map is marked with the positioning landmarks, wherein the wireless communication functions of the plurality of fixed positioning landmarks and a communication function of the mobile communication device are respectively comprising communication functions based on wireless communication technologies in Internet of Things (IoT).
