The location algorithm based on arrival time difference has high complexity and high system power consumption. When using the traditional TDOA positioning algorithm to locate, we will encounter over-determined nonlinearity of positioning equation, and you need to use iterative method to solve it. Based on this, this paper proposed a hybrid positioning algorithm of TDOA and AOA. Combining the TDOA and AOA information, the problem of solving the iterative positioning equation was simplified successfully, which reduced the complexity of the algorithm and reduced the system power consumption. At the same time, in order to solve the problem of high system power consumption, this paper also proposed the use of Zigbee protocol instead of the traditional Wi-Fi protocol to develop the positioning system, thereby effectively reducing system power consumption, increasing system life and improving system applicability.
