Phase I

Contract Number: FA8649-21-P-0648
Start Date: 2/8/2021    Completed: 5/8/2021
Phase I year
2021
Phase I Amount
$49,960
Atmospheric drag is the biggest source of error and the least predictable perturbing force acting on spacecraft and space debris objects in orbit around Earth. The U.S. Air Force uses the High accuracy satellite drag model (HASDM) to predict the atmospheric drag effects. Kayhan Space in collaboration with the University of Colorado Boulder seeks to improve the HASDM by decoupling and simultaneously solving for the atmospheric density and the coefficient of drag of the HASDM calibration satellites. This would significantly improve the accuracy of trajectory predictions of space objects and debris in low earth orbit (LEO). This project directly impacts the warfighter’s ability to protect U.S. space assets from threats of collisions or other adversarial intent.

Phase II

Start Date: 9/3/2021    Completed: 12/5/2022
Phase II year
