Abstract:
Lately we can see the intentional development of providing the Earth remote sensing (ERS) services. This is indicated by the facts of development of Russian and world providers of images of high resolution to customers. Due to the facts of increasing need to have the images of the Earth from space, improvement of systems based on satellites on geostationary orbit and that current ERS systems become more complicated, delivery in time and storage on the Earth of large amount of information become a topical issue. Now the data rates vary from 100-200 to 400-800 Mbit/sec. To provide continuous data transmission it is necessary to deploy more receiving ground stations in different latitudes depending on orbit parameters of ERS satellites. This makes the system more expensive and the ground segment unreasonably more redundant. Another way to transmit the data from ERS satellite is to use satellite system based on geostationary relay satellites that will ensure continuous twenty-four-hour data transmission from ERS satellite to gateway, which then will transmit the data to ERS data collecting & processing center via optic lines. This paper contains the analysis and solutions for transmission a large amount of information via satellite to geostationary orbit.
