🔍 Key Concepts

• Running fix vs. fix (simultaneous position)** • Using bearings of fixed objects over time with dead reckoning (DR) positions • Minimum information needed to determine a single point on a chart

💭 Think About

• Think about how many lines of position (LOPs) are required to determine one position on a chart. • In a running fix, are all bearings taken at the same time, or at different times? How does that affect how many fixed objects you need? • Compare a running fix to a standard fix: what is similar about the geometry of the LOPs at the final time?

✅ Before You Answer

• Recall that each bearing to a fixed object gives you one line of position (LOP). • Ask: to get a unique point on the chart at the time of the running fix, how many LOPs must intersect? • Verify in your notes: does a running fix change the number of LOPs required, or just the timing and construction of them?
