Inter-Satellite Distance Calculator
Inter-satellite distance refers to the physical distance between two satellites in space, typically measured in kilometers or miles. It is used for the design and operation of satellite networks, particularly in constellations or systems involving multiple satellites.
For nearly circular orbits, the orbital radius refers to the distance between an object in space and the body it is orbiting. When an object orbits a body, it moves around it, tracing a path that forms either a circle or an ellipse, depending on the nature of its orbit.

D1: orbital radius of the first satellite
D2: Orbital radius of the second satellite
θ: The angle formed by two radii of satellites to the center of the earth
Applications of Inter-Satellite Distance
- Satellite Constellations: In systems like Starlink or Iridium, maintaining optimal distances ensures consistent global coverage and network reliability.
- Satellite Navigation: Accurate inter-satellite distances are vital for systems like GPS, GLONASS, and Galileo to provide precise positioning.
- Earth Observation: Satellites in constellations like Sentinel or Landsat rely on specific distances to avoid overlap or data gaps.
- Inter-Satellite Links (ISLs): Modern communication networks use ISLs to relay data directly between satellites, reducing the need for ground stations. The efficiency of these links depends on the inter-satellite distance.
For example: if D1 Is 2000 Km, D2 is 4000 Km, θ is 55 Degrees
then,
Inter-Satellite Distance Calculator =√(D12 + D2 2 − 2D1D2 cos (θ ))
