There are several ways to determine the observed location:

• Terrestrial navigation:
  • Cross bearing
  • Sailing bearing
  • Bearing and distance (fire in the rear sight, radar distance)
  • Bearing and sounding
• Electronic navigation:
  • Position information of a satellite navigation system
• Astronomical navigation:
  • Position finding through astronomical navigation

Notation

The observed place always relates to a specific point in time and is indicated as follows:

O _b 1200: 50 ° 12 N, 002 ° 01 W.

Use in shipping

The determination of the O _b is used to determine the position of a ship. The further journey can be planned from the O _b , or the route covered so far can be checked. It also serves to determine the cutlery offset in relation to the coupling point .
