Embodiment Construction
[0021] figure 1 As shown, this embodiment provides a highly stable beacon source, which includes:
[0022] The constant temperature crystal oscillator unit is used to provide a highly stable beacon reference signal, including the first crystal oscillator A and the second crystal oscillator B;
[0023] A power supply unit, configured to provide the constant temperature crystal oscillator unit with a voltage required to output a beacon reference signal;
[0024] The beacon signal selection unit 4 receives external beacon selection remote control instructions 3, controls the power supply unit to select the first crystal oscillator A or the second crystal oscillator B to supply power, and outputs the beacon of the first crystal oscillator A or the second crystal oscillator B reference signal;
[0025] The output unit receives the beacon reference signal output by the beacon signal selection unit and outputs two high-isolation beacon signals.
[0026] The two constant temperatur...
