| titleOfInvention | Clock offset compensation system and method for improving TDOA positioning accuracy |
| abstract | Clock offset compensation system for improving TDOA positioning accuracy, including microcontroller MCU, said microcontroller MCU is controlled by digital phase detector and data bus and reference clock source control and data bus is connected with digital phase detector and reference clock source respectively The clock source establishes a two-way connection, and the microcontroller MCU also establishes a two-way connection with the first UWB receiver and the second UWB receiver through the UWB receiver data bus. The first UWB receiver and the second UWB receiver are respectively provided with a second A phase-locked loop and a second phase-locked loop, the first phase-locked loop and the second phase-locked loop are respectively connected to the reference clock source through the first clock signal line and the second clock signal line, and the digital phase detector is respectively connected through the first The first phase measurement line and the second phase measurement line are connected to the first clock signal line and the second clock signal line; this system has the advantages of low implementation cost, low calculation resource consumption, sub-nanosecond synchronization accuracy, and high positioning accuracy. |
