The CDMA time-correcting pointer clock is an intelligent civilian clock product developed by Yantai Clock and Watch Research Institute Co., Ltd. It has the functions of receiving CDMA standard time signals, keeping synchronization with standard time, low power consumption design, power-saving receiving mode and working mode, etc. It uses a specially customized CDMA circuit module, and uses the precise satellite time provided by the CDMA mobile phone network signal, which is widely used, has a wide signal coverage, and has a strong signal strength, as the standard time to correct the pointer quartz clock. The product can be placed at any location. Even in a building, the CDMA signal is very strong, which greatly avoids the disadvantages of weak radio clock signals that cannot be received or decoded incorrectly. It has a built-in receiving antenna like a mobile phone, which is easy to install and suitable for various occasions such as home and office. The dedicated CDMA circuit module can provide accurate satellite time. The theoretical error of the time it provides is almost 0, and the actual error does not exceed 5 milliseconds. In the extreme case of not receiving CDMA signals, the circuit module also supports manual adjustment of the hour, minute, and second hands, and saves the time to the backup clock module. The use of software compensation algorithms and hardware capacitor fine-tuning technologies ensures that the pointer indicates the time accurately. Without using CDMA time calibration, the cumulative error of the quartz clock's self-operation in a day is less than 100 milliseconds.
