Satellite orbits optimized for satellite supported services on the territory of Croatia

摘要

Modeling of satellite orbits that are used to design satellite supported services on the territory of Croatia is presented in this paper. Modeling of the Kepler's orbit elements is used to optimize satellite orbits considering the territory of Croatia. The paper describes the process of designing the usage of the modeled satellite orbits i.e. Meteorological (CROMETEO) and fire protection (CROFIRE) satellite supported services designed for the territory of Croatia. Meteorological service is designed to use two satellites. One is in optimal orbit over the territory of Croatia for periodical measurements of the atmosphere parameters and the cloudiness in higher spatial resolution, while the other is in the geostationary orbit to continuously monitor the atmosphere and the cloudiness. Fire protection satellite supported service uses a satellite optimized to monitor fire risk, detect fire early, support fire extinguishing and assess fire damage.
