    Satellite Internet access is Internet access provided through communications consumer grade satellite Internet service is typically provided to individual users through geostationary satellites that can offer relatively high data speeds, with newer satellites using K u band to achieve downstream data speeds up to Mbit/e: ITU. The GPS-aided GEO augmented navigation (GAGAN) is an implementation of a regional satellite-based augmentation system (SBAS) by the Government of India. It is a system to improve the accuracy of a GNSS receiver by providing reference signals. The AAI's efforts towards implementation of operational SBAS can be viewed as the first step towards introduction of modern Communication, navigation and Developers: Indian Space Research Organisation, .

Abstract. The domain of space avionic systems is changing extremely rapidly, compared to other technical domains in space-faring industry, under the pressure of an intense competition, the continuous emergence of new markets and players, the need for cost reduction, as well as an increased obsolescence rate of components and by: 8.

This paper presents a study with university satellite software projects and proposes a set of good practices for the development of On-board Data Handling embedded software. Considering high costs and complexity of commercial satellite projects, the characteristics of university satellite projects demand a different approach to systems.

Mostert, W.A. Halang. The attitude (or orientation) control subsyste m is responsible for maintaining a satellite’s orientation in terms of its local coordinate system: yaw, pitch, and roll, as shown in Figure 4a. Without attitude control, a satellite will not be able to point its communication antennas towards Earth at all times.

The resulting resource management achieves the goals of avoiding on-board congestion situations, guaranteeing an efficient use of the satellite resources and limiting the on-board processing complexity. Software simulations have been performed with the OPNET tool, in order to test the effectiveness of the proposed by: satellite network.

The first one is the long propagation delay between the satellite and the access units. This implies that the close loop control between the BoD controller (either located on the satellite or in the NCC) and the SAU will be difficult.
