GPS Countdown Timer Display
We provide highly accurate digital LED displays, including a GPS countdown timer display. It is a high-performance, high precision time display device. Scientifically designed and manufactured, the digital LED display can receive standard time signals from the GPS satellites and clearly display them on screen. The LED timer display can be installed both indoors and outdoors.
Our digital LED display uses industrial grade, high-precision, built in GPS timing modules that uses the world’s leading GPS chip (U-Blox NEQ-6Mas) as the core chip. Mastering the core technology of sensitive GPS satellite signal reception, we have optimized the PCB layout and routing, bringing a more stable signal and reception and faster positioning. Under environmental protection premises, the highly sensitive LED countdown clock can achieve a normal and accurate GPS signal reception if placed near an indoor window.
