Description

SatLife is a tool for predicting the orbital lifetime of a satellite, from initial orbit through atmospheric reentry. SatLife takes into account the satellite's initial orbit conditions, area and mass. It also uses historical or projected solar cycle information to predict atmospheric drag.

The stand alone version of SatLife can run lifetime analyses for a family of circular orbits, with varying start dates, initial altitudes or ballistic coefficients or for a single elliptical orbit. It outputs the predicted lifetime to the screen and a time history of the altitude to a file in a format compatible with most spreadsheet programs for plotting. For circular orbits, the history consists of the altitude as a function of the number of days on orbit. For elliptical orbits it consists of the apogee, perigee and eccentricity as a function of the number days on orbit.

The STK/SatLife Module takes the initial orbit conditions of any STK satellite and a user input ballistic coefficient. It displays the calculated lifetime in a standard STK utility window. The time history of the satellite's apogee, perigee and eccentricity can be displayed in an STK Data Window, with options to save, export or print the results.

SatLife uses a variable step size Euler integrator to combine high fidelity with good performance even on high altitude orbits with very slow decay rates.
