We are developing SPRESENSE with ArduinoIDE. It takes a long time to fix with GPS reception, so I can't use low power.Please tell me how to speed up GPS reception confirmation.

# include <RTC.h>

    Serial.println("Power on reset";
    Gnss.start(COLD_START);
  } else{
    Serial.println("Wakeup from deep sleep");
    RtcTime now = RTC.getTime();
    // Print the current clock
    printf("%04d/%02d/%02d%02d:%02d:%02d\n",
