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.

Technology development, standards and cost effective systems have been evolved in association with various state governments, NGOs, speciality hospitals and industry. National GIS is a major initiative of organising the image and spatial data assets and make them accessible to users — for both viewing and physical access.

Email required Address never made public. Achievements of CAPE include evaluation of multi-date remote sensing data for crop identification, creation of a geo-referenced cadastral data-base for accuracy evaluation, development of yield models using trend and weather data.

GRAMSAT Satellites: Overview

Work is nearing completion in Gujarat and Orissa. This is the distinguishing feature of a VSAT system, the earth-station antennas being typically less than 2. To determine distance between two points or how far you are from another location.

The work involved preparation of maps on 1: Comprehensive digital database has been created for all the 16 districts. Chhatisgarh State Developmental Planning: BTV provides yet another piece of the education menu and is another way to provide professional development.

Demonstrative studies on its utilisation have focused on land records metrology, land parcel mapping, city guide map updation, terrain parameter retrieval, base map generation, etc. Concurrent monitoring is on in all the watersheds. 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.

What is GRAMSAT?

Space Segment — Satellites orbiting the earth consists of 29 satellites circling the earth every 12 hours at 12, miles in altitude. High resolution satellite data helps to capture the existing irrigation infrastructure and to monitor the progress of new irrigation potential created under programs such as the Accelerated Irrigation Benefit Programme AIBP and Central Loan Assistance Programme.

By using digital encoding techniques, more users can share the same frequencies than had been available in the analog systems. Communicaton many as 74, wells have been drilled in seven states with the overall success rate of 90 percent and about 3, recharge structures have been constructed. Glacier Atlas of Chenab basin containing glaciers spread over an area of sq km was published showing extent of glaciers and related features.

The programming on BTV networks is extremely cost-effective compared to seminar fees and downtime for travel.

To make this website work, we log user data and share it with processors. Concerns were raised about flooding in the valley if these tons of accumulated snow melted. One such site is a fortified structure identified as Kotda archaeological site, which has been confirmed on ground by Directorate of Archaeology, Gujarat based on the pottery, copper coins, millstones, skulls, etc.

Location and attributes of 6 lakh poles covering 63 electric supply units were collected to facilitate development of power GIS applications. Institution updates, news, training, meetings and other events can be broadcast live to multiple locations.

Study in Andaman and Nicobar islands has been completed during the year and reports, atlases and CDs have been published and distributed to the users such as Department of Biotechnology, State Forest Departments, Ministry of Environment and Forests, subject experts, etc.

About disaster watch reports and over 40 flood monitoring maps were generated. Chapter VI Data Communication: This Gramsat satellite is carrying six to eight high powered C-band transponders, which together with video compression techniques can disseminate regional and cultural specific audio-visual programmes of relevance in each of the regional languages through rebroadcast mode on an ordinary TV set. The participants at the classrooms located nationwide receive lectures through simple dish antennas and have facility to interact with lecturers using telephone lines.

You can leave a responseor trackback from your own site. Initially developed to support a standardized approach to digital cellular communications in Europe, the “Global System for Mobile Communications” GSM protocols are rapidly being adopted to the next generation of wireless telecommunications systems. Registration Forgot your password? The satellite effectively places people in the same room, so that sales personnel in the field can learn about new products at the same time.

The receiver already knows the velocity, which is the speed of a radio wave ormiles per second the speed of light. Satellite archaeology is based on study of geometric patterns of soil and vegetation marks, palaeo-channels, palaeo-mudflats, and trend lines. Cellular Network Basics There are many types of cellular services; before delving into details, focus on.

GRAMSAT Satellites: Overview

This service swtellite known as Direct To Home service. It is being used by many industries including brokerage firms, pizza houses, car dealers and delivery services. GSM uses several cryptographic algorithms for security. Typical user groups include banking and financial institutions, airline and hotel booking agencies, and large retail stores with geographically dispersed outlets.

Since this is used for the first access attempt by users of the network, a random access scheme is used to aid in avoiding collisions. Some of the major application projects carried out during the year are highlighted in the following paragraphs. About project SlidePlayer Terms of Service.

Working principal of DTH is the satellite communication. Training workshops have been organised in all the states to demonstrate the utility of these maps for selection of well sites and planning recharge structures. When implemented, the Indian SBAS system will play an important role in the introduction of satellite based navigation services in the Asia Pacific region.

Development of ASAR to support all-weather monitoring capability is in an advanced stage. A form of demand assigned multiple access DAMA is employed in some systems in which channel capacity is assigned in response to the fluctuating demands of the VSATs in the network.

The creation of a digital database with GIS layers on land-use and land-cover, infrastructure and geomorphology for 60 districts in five states Assam, Bihar, Orissa, West Bengal, Andhra Pradesh is near completion. The trend is toward even smaller dishes, not more than 1.
