A fix involving GPS, intersections of radar ranges, and possibly visual LOPs from simultaneous observations is called what?

• A. Visual Fix
• B. Running Fix
• C. Electric Fix
• D. Dead Reckoning

Answer: (C)

An electronic fix is obtained by combining electronic navigation tools with sighted observations to pinpoint your position. GPS provides a direct position from satellites, while radar gives intersections of ranges to known objects, forming lines of position. When you add simultaneous visual lines of position from observed objects, you have multiple independent measurements that intersect at a single point. Using GPS, radar range intersections, and visual LOPs together reduces uncertainty and yields a reliable fix quickly, especially in poor visibility or when one method alone isn’t enough. This differs from a visual fix (relying only on sighted objects), a running fix (taken while moving using successive observations), or dead reckoning (estimating position from last fix without new external measurements).
