EARTH POSITIONING SYSTEM
First 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 a fixed electric household appliance;
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.

Abstract
An earth positioning system (EPS) is provided. The EPS includes a plurality of fixed LED lights with communication functions and a mobile communications device. A cloud computer and at least one map marked with world coordinates of the fixed LED lights may be further included. The LED light includes a substrate, at least one LED die, a power supply, a wireless communication module, a control unit and a housing. The LED lights may be arranged in indoor and outdoor environments, with coordinates represented in longitude, latitude and altitude. The coordinates are included in a map data of the cloud computer. When the mobile communication device moves with its carrier, the world coordinates of the mobile communication device can be located based on the coordinates of the LIED lights nearby or based on the unique IDs of the LED lights together with the aforementioned map.
