🔍 Key Concepts

• Voluntary Observing Ship (VOS) position group on WS Form B‑80 • How latitude and longitude are rounded and ordered in the encoded position group • The use of leading 9s and direction codes (N/S/E/W) in VOS code groups

💭 Think About

• Look at the position (64°42'N, 02°28'W) and decide to which whole degree and whole 10‑minutes it would be rounded for this code form • Determine how many digits are used for latitude vs longitude in the BBXX position group on the form D041NG • Figure out what the leading digit(s) represent in the sample code groups printed on the form—are they degrees, tens of degrees, hemisphere indicators, or something else?

✅ Before You Answer

• Verify how degrees and minutes of latitude are written (total number of digits and placement of N/S) in the BBXX example on the illustration • Verify how degrees and minutes of longitude are written (including whether 1-, 2-, or 3‑digit degrees are used and where E/W appears) • Confirm what the initial 9 or 99 at the start of the position group signifies on this specific WS Form B‑80 code (do not assume from other code forms)
