FCC Great Circle Distance and Bearing Calculation

This utility uses WGS84 approximation to calculate great circle distance and bearing between two geographic points. Also it perfroms the second distance calculation between two geographic coordinates based on FCC 73.208 rule, which is considered by FCC as a valid approximation for distances less than 470 km.

1st Geographic Coordinate
  • Latitude valid formats:
    "Decimal" (ex. '38.889139') or
    "Degrees Minutes Seconds" (ex. '38 53 20.9 N')

  • Latitude:

  • Longitude valid formats:
    "Decimal" (ex. '-77.049') or
    "Degrees Minutes Seconds" (ex. '77 2 56.4 W')

  • Longitude:
