Planet positions for the Multi Face GPS Clock

Another update, this time to add:

  • Azimuth and elevation for inner and outer planets relative to your present location. The inner planet screen shows Venus and Mercury and alternates also every 10 seconds between showing the position of the sun and the moon. The % illumination is also shown along with an estimate of apparent magnitude
  • The combined local time and UTC display now has an option to show ISO week number, defined to start on Mondays. (It is my understanding that the week number in the US is different, as Sunday is the first day of the week)
  • A new calendar screen now shows Gregorian (western), Julian (eastern) as well as Islamic and Jewish dates. The calculation of the Jewish calendar is tough for the Arduino Mega and takes some 5-6 seconds
  • A screen showing GPS Info has also been included. This screen shows the number of satellites in view (line 0), the number of satellites in use for position fix and their average signal to noise ratio (line 1), the mode and status indicators (line 2), and the Horizontal Dilution of Precision, Hdop, and its characterization in plain text (line 3).
