sci.dead-reckoning-position Calculator
Calculates position from last known location using dead reckoning: position = previous + speed × time × direction unit vector. Dead reckoning error accumulates without external position fixes — INS errors grow at ~1 nm/hour; GPS-aided INS corrects continuously.
Inputs
Lat0 Deg
Reference formula or conversion factor shown for context.
Lon0 Deg
Reference formula or conversion factor shown for context.
Speed Knots
Rate of movement. 1 m/s = 3.6 km/h = 2.237 mph.
Heading Deg
Reference formula or conversion factor shown for context.
Time Hr
Duration of the process. Make sure units match the rate inputs (seconds, minutes, or hours).
Results
estimated latitude (°)
The value at the specified point or condition.
estimated longitude (°)
The value at the specified point or condition.
distance traveled (km)
The computed distance or separation.
distance traveled (nm)
The computed distance or separation.
spherical earth dead reckoning
pH of the solution. Below 7: acidic. 7: neutral. Above 7: basic (alkaline).
error growth
The absolute increase in value over the period. Growth = final value minus initial value.
