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, .

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.
The one-way propagation delay time between a GEO satellite and an access unit is msec.
