Simulation of ADEOS-II Orbit Determination
Process of precise orbit determination of Earth observing satellite, ADEOS II was simulated by use of orbit analysis software, GEODYN II. To improve orbit determination accuracy of ADEOS-II composed of box-like main body and a large solar panel, non gravitational force model was developed. The shape of the satellite was assumed to be a combination of fourteen flat plates including two movable plates which corresponds to the rotating solar panel. Area and refelectivity of each plate were determined from the engineering specifications of ADEOS II. The non gravitational forces acting on each plate, such as atmospheric drag, solar radiation pressure, and albedo from the Earth, were computed independently and summed vectorially to get acceleration on the center of mass of the satellite Tlus model improves the orbit accuracy compared to " cannonball model," a conventional non gravitational force model used for orbit determination.

Summary: | Process of precise orbit determination of Earth observing satellite, ADEOS II was simulated
by use of orbit analysis software, GEODYN II. To improve orbit determination accuracy of
ADEOS-II composed of box-like main body and a large solar panel, non gravitational force model
was developed. The shape of the satellite was assumed to be a combination of fourteen flat plates
including two movable plates which corresponds to the rotating solar panel. Area and refelectivity
of each plate were determined from the engineering specifications of ADEOS II. The non gravitational
forces acting on each plate, such as atmospheric drag, solar radiation pressure, and albedo
from the Earth, were computed independently and summed vectorially to get acceleration on the
center of mass of the satellite Tlus model improves the orbit accuracy compared to " cannonball
model," a conventional non gravitational force model used for orbit determination. |
