LM Space Constellations iPad vs Our Nuclear Timeline

The satellite business is exciting with rapid innovation, increasing investment, new customers and new competitors. Satellites and their associated systems on the earth perform missions or services from low altitudes (e.g. imaging), medium altitudes (e.g. GPS navigation signals) and high altitudes (e.g. TV signals). There are many factors to consider in designing a satellite constellation. A large number of economic, technical, and social factors are considered and optimized to best achieve the objectives of that business. LM Space Constellations provides an introduction to a couple of key factors. Change these factors and observe their effects. Start learning the basics of satellite mission architecture.
