50+ Engineering Calculators
Orbital mechanics, link budgets, radiation environments, and more — built into every SMAD Portal plan. No MATLAB license required.
Hohmann Transfer Calculator
Calculate delta-V requirements for Hohmann transfer orbits between two circular orbits. Includes transfer time, fuel mass estimates, and orbit visualization.
Learn more →Link Budget Calculator
Analyze RF communication link margins for spacecraft-to-ground and inter-satellite links. Accounts for path loss, antenna gains, atmospheric effects, and noise.
Learn more →Delta-V Budget Calculator
Build a complete delta-V budget for your mission. Sum maneuver costs, compute fuel requirements, and track margin against propulsion system capacity.
Learn more →Orbital Decay Predictor
Predict orbital lifetime for LEO spacecraft. Models atmospheric drag using ballistic coefficient, solar activity, and altitude-dependent density profiles.
Learn more →Ground Track Visualizer
Visualize spacecraft ground tracks on a 2D map projection. See coverage patterns, revisit times, and ground station access windows for any orbit.
Learn more →Radiation Environment Calculator
Estimate the radiation environment for your orbit. Compute total ionizing dose, single event upset rates, and shielding requirements for spacecraft electronics.
Learn more →These are just a few of the 50+ calculators included in SMAD Portal. The full suite covers orbital mechanics, thermal analysis, structural sizing, communications, propulsion, and more.
