| Summary: | The paper describes the orbit design and
lifetime analysis of MYSat, a university-built nanosatellite
for measuring electron-density in the Ionosphere E-layer.
Low earth orbit is selected for MYSat orbit due to the
deployment method using Japanese Experiment Module
Small Satellite Orbital Deployer at International Space
Station. The analysis is done using Analytical Graphics,
Inc.’s System Tool Kit to obtain MYSat classical orbital
elements and orbital lifetime. Comparative study has been
conducted on different propagators and atmospheric model
to predict MYSat’s possible orbital decay time for
preliminary subsystem design of MYSat. The orbit for
MYSat is a near-circular orbit with an average altitude of
404 km. Thus, the lifetime of MYSat is expected about 1.4 ~
1.9 years. However, in a real condition the expected lifetime
will be different due to the accuracy of the mathematical
model and the environment data. Nevertheless, the satellite
preliminary subsystem design and ground operations can
be arranged using the estimation. |
