Digital Time Zone Display
Digital Time Zone Display is a GPS based LED time zone display. The GPS time is acquired with an inbuilt GPS tracking device. The GPS tracking device has capability of capturing GPS information from 12 satellites simultaneously giving us the required accurate GPS time signal. It has the provision to display UTC with three city names with time zones, current date and day of the location. Coordinated Universal Time (UTC) is taken as the time reference and with respect to UTC, three different zone time,date and day can be displayed. In case of any loss of GPS signal , the time is updated by using the internal Real Time CLock (RTC) and on availability of GPS signal the time automatically synchronizes with the GPS time.
The Digital Time Zone Display can be interfaced with custom PC based Graphical User Interface software to modify and update the display information like change of city name, time, date and day. It has the provision to display the room temperature with considerable accuracy using a temperature sensor mounted on the enclosure.
Another feature of this Digital Time Zone Display is that the time can also be synchronized by the Network Time Protocol.
