The Digital Satellite Clock is a simple, easy-to-use, autonomous clock. What makes this clock “autonomous” is that you never need to set the time — you simply turn it on and it will display the current time using signals received from global navigation satellite system (GNSS) satellites that are orbiting the earth. Plus, the clock contains an internal rechargable battery so that it can operate for extended periods when the external power goes out. The clock can be ordered with a Blue Red or Green digital LED matrix display.

UTC time (Coordinated Universal Time) is displayed in 24-hour format by default on the clock ( unless it was ordered with custom time zone and/or daylight savings time settings).
