Geochron World Time Clock
Geochron is a wall clock with the world map plus faded in, season-corrected day and night division (terminator). Since the 1970s there is a so-called "CIA clock". And this has always been an eye-catcher in the shack or in the office. Also a corresponding PC software exists already longer, even if only with a rather simple representation.
This representation of the world - but in a new, brilliant sharpness and detail - is offered by the product 'Geochron'. Geochron is a stand-alone display unit that uses an HDMI video output to address an HD, Full-HD or 4K screen. The earth's surface is displayed in Mercator projection. So far this is known, but what makes Geochron special are the additional functions. Besides the well-known representation of the day/night zones and the Greyline, which is very important for the radio amateur, a multitude of overlays are offered, which partly also adapt live to the actual conditions.
The representation of the earth's surface with the day and night borders is very interesting for radio amateurs, because very good propagation conditions for the radio on short wave can result along the day/night border. Geochronous shows the position of this limit exactly to the minute and adapted to the season. In addition, static and dynamic (live) overlays are offered. Live overlays require an active Internet connection of the Geochron unit.
Static overlays show, for example, geopolitical conditions such as national borders, large settlements and much more. Particularly impressive is the night-time representation with the lights of the big cities. For each place the actual sunrise and the twilight times can be indicated. In addition, there is the display of world shipping and flight routes, topographical information, display and prediction of solar radiation and many other options.
Live overlays show the current weather all over the world, but also for radio amateurs interesting data such as satellite positions. The data of the amateur radio satellites are displayed, but also such interesting information as the NOAA weather satellites, the position of the ISS, Iridium satellites or the rocket launches of the last 30 days. User-defined, up to 16 positions on Earth can be marked with the respective local time.
The great advantage of Geochron with its many functions is the simple commissioning and operation. So no computer knowledge is necessary, you only have to set up the internet access (Wifi or cable) and connect a screen. Of course a nice big flat screen with high resolution (Full-HD or 4K, not included) is worth it. Geochron is delivered with a power supply (12V, 1.5A), a HDMI cable and an IR remote control.
