Abstract
GLONASS, a satellite navigation system developed in Russia since 1976, is defunct
and orbits in an unstable attitude. The satellites in these problems are not managed and
there is no precise information, which can increase the risk of collisions with other
space objects. In this study, detailed attitude dynamic have to be analyzed through
photometry data, which requires spin period and spin axis. The light curve data is
obtained by observing through the photometer at the Graz station and the power spectrum
is calculated to obtain the cycle of the satellite. The geometric relationship between
observer and sun is analyzed for GLONASS-50 satellite. The box-wing model is applied to
obtain the phase reflection of the satellite and obtain the Irradiation of the satellite
through this information. In Light Curve and Irradiation, the spin axis is calculated
for each peak points with the distance square minimum technique. The spin axis of the
GLONASS-50 satellite is RA = 116°, Dec = 92°.
期刊介绍：
JASS aims for the promotion of global awareness and understanding of space science and related applications. Unlike other journals that focus either on space science or on space technologies, it intends to bridge the two communities of space science and technologies, by providing opportunities to exchange ideas and viewpoints in a single journal. Topics suitable for publication in JASS include researches in the following fields: space astronomy, solar physics, magnetospheric and ionospheric physics, cosmic ray, space weather, and planetary sciences; space instrumentation, satellite dynamics, geodesy, spacecraft control, and spacecraft navigation. However, the topics covered by JASS are not restricted to those mentioned above as the journal also encourages submission of research results in all other branches related to space science and technologies. Even though JASS was established on the heritage and achievements of the Korean space science community, it is now open to the worldwide community, while maintaining a high standard as a leading international journal. Hence, it solicits papers from the international community with a vision of global collaboration in the fields of space science and technologies.
