Node spacing
The node distance is generally the distance between two nodes .
- Nautical: The basic dimension of a log line , the knot cord for measuring speed.
- Physics: Half the wavelength of a standing longitudinal wave : d = λ / 2
- Mechanics: Euler's angle ϕ
- Astronomy: The distance of a celestial body from its ascending node, the coordinate in the orbit system .
- For GPS and Galileo satellites: A measure of the distribution of the various orbital planes along the equator.
