Step-by-Step Mathematical Derivation

1. Given Input Coordinates:
  • Start Point: (40.7128°, -74.006°)
  • Bearing: 45°
  • Distance: 100 km
2. Model & Ellipsoid Reference:WGS-84 / Earth Sphere R = 6,371 km
3. Governing Geodesic Formula:φ2 = asin(sin(φ1)cos(d/R) + cos(φ1)sin(d/R)cos(θ))
4. Variable Substitution:R = 6,371 km
5. Interpretation & Practical Application:

Traveling 100 km at bearing 45° arrives at coordinates (41.345636°, -73.15895°).

Mathematical Formula

lat2 = asin(sin(lat1)cos(d/R) + cos(lat1)sin(d/R)cos(θ))

Overview & Explanation

Performs spherical dead reckoning to project new coordinates along a given vector.

How It Works

  • Projects distance along great circle at initial azimuth.

Practical Applications

  • Flight vectoring.
  • Search and rescue radial search.
  • Drone pathing.

Frequently Asked Questions

Can bearing be negative?
Bearings should be specified from 0° to 360° (0° = North, 90° = East, 180° = South, 270° = West).
