View-From-Space Map
Shown above is a map of the earth as seen from space
(orthographic projection), centered on London.

GeoClock has a wide variety of these map types

• The Windows version also includes Screen Saver and Wallpaper modes. However, be aware with the various changes to these Win-OSes from Win3.1x to Vista, using these may be problematic.

• GeoClock Pro shows the current time (based on your computer's clock) with a high quality map of the earth. The current sun position is displayed, and the parts of the earth in sunlight and twilight are highlighted. This display is automatically updated every few seconds. Local sunrise, sunset, the sun's azimuth and elevation, and times around the world are also displayed. A variety of map backgrounds and other options are available.

• With a registered copy of GeoClock Pro, you get the latest versions of the programs, 45 maps, zoom, distance measuring, local time displayed next to the city names, and immediate map display.

• GeoClock Pro can be used to watch the day-night terminator as it approaches your station. This is particularly useful during contests, when the higher-frequency bands often open at the onset of the daylight hours.

• GeoClock Pro includes the HAM PACKAGE Plugin to provide special functions for HAM radio operators. It provides graphical display of remote station location, propagation path, and D and F layer illumination, together with key location, pointing, distance, and time data. The Ham Package includes a custom Azimuthal-Equidistant map centered on your HAM station, a call sign data base, and utility programs.

The HAM PACKAGE functions include:
• Azimuthal-Equidistant (Great Circle) map centered on your station
• Twilight and terminator, or D and F layer illumination, display
• User Maintainable call sign data base
• Remote station location
• Short and long great circle path
• Short and long path azimuth and range
• Remote station (reciprocal) azimuth
• UTC, local, and remote station local time
• DXCC and WAE designations
• CQ and ITU zones
• Continent, area, and location names
• Optional use of QRZ CD-ROM for US call signs.

• With ACE-HF installed on your PC, GeoClock can be used together with ACE-HF (System Simulation & Visualization Software) so you can watch the Open Bands Boxes and the circuit prediction charts while keeping an eye on the GeoClock terminator display. One handy screen arrangement is to call GeoClock from the ACE-HF Circuit Analysis screen, and then use the GeoClock Window Controls to reduce its window size. Put GeoClock in the upper-left corner of the screen.

• If you call the ACE-HF SNR Summary Chart, you can watch the summary predictions -- and even the ID timer if you have started it -- as well as the Main Chart predictions while you note the terminator's passage in the GeoClock window.

• ACE-HF (Animated Communications Effectiveness, High Frequency) is a new product based on the proven VOACAP program with a new interface and display routines based on GeoClock. Click the link below to read more about ACE-HF..
