GRAMSAT IN SATELLITE COMMUNICATION PDF

of India has sponsored the GRAMSAT programme, which is operating in Orissa. .. Satellite communication networks have been an indispensable part of most. Commissioned in , INSAT is the largest domestic communication system in the Asia This Gramsat satellite is carrying six to eight high powered C-band. Guided with these views a dedicated satellite called GramSat is being planned for rural development and tele-education in India. It is desirable that system.

The available bandwidth uplink and downlink is seen to be MHz. Coastal, mangroves and coral reefs studies: Since this is used for the first access attempt by users of the network, a comunication access scheme is used to aid in avoiding collisions. DOT has licensed a few private operators to provide value-added services to the public using the extended C-band. We think you gdamsat liked this presentation. Funded by the Ministry of Rural Development, this project envisages preparation of land and water resource management and utilisation plans on 1: This communciation service is provided using small hand-held terminals.

Most of the maps and atlas available in different states are of symbolic in nature and the command boundaries and locations are only tentative lacking geographic correspondence.

Upper winds, sea surface temperature and precipitation index data are regularly obtained.

The networks provide computer connectivity, data broadcasting, TV broadcasting facilities having applications like e-governance, National Resource Information System NRISdevelopment information, tele-conferencing, disaster management, telemedicine and distance education.

Land parcel maps have been prepared for a few villages. A device called the Subscriber Identity Module SIM that is basically a smart-card provides custom information about users such as the services they’ve subscribed to and their identification in the network The Base Station Sub-System BSS The BSS is the collection of devices that support the switching networks radio interface.

Mapping for 14 sites has been completed and the final product communicahion available. The user feedback indicates good success for targeting water. If your work involves or is likely to involve some form of wireless public communications, you are likely to encounter the GSM standards. The website has been launched and generation of the same in the regional language has been completed.

Exact delineation of command boundaries using multitemporal satellite data crop extent and updation of canal network are also envisaged in this project.

To navigate from one location to another for example, you need to travel from a lookout to the fire perimeter.

GRAMSAT Satellites: Overview

Development of Coastal Zone Information System is in ni. Most of the TV channels are digitised. Astrium’s service allows Inmarsat users to send and receive directly through the Internet without accessing a public telephone network.

The programming on BTV networks is extremely cost-effective compared to seminar fees and downtime for travel. Desertification Status map on 1: The expertise of the best instructors can be delivered to thousands of people without requiring trainers to satelllte to the site.

What is GRAMSAT?

Its recent growth began with the introduction of the video cassette in the early s. It allows identifying the gap areas and species-habitat relationship and helps biodiversity conservation and planning by setting priorities.

Short messages from user terminals are relayed through the satellite to the hub and are automatically forwarded to the respective user headquarters via Fax or data links. It is possible to configure a video conference bridge to show all sites at the same time on a projection screen or monitor.
