The objectives include establishment of natural resources database, geo-referencing of village maps and development of land information system and development of road information system. In this project all the major and medium command boundaries number will be registered and brought onto single platform and scale 1: During the year, support and services were provided during natural disasters such as floods, drought, cyclone, earthquake etc.

Institution updates, news, training, meetings and other events can be broadcast live to multiple locations.

By using digital encoding techniques, more users can share the same frequencies than had been available in the analog systems. Exact delineation of command boundaries using multitemporal satellite data crop extent and updation of canal network are also envisaged in this project. It is under implementation for North-Eastern region. The trend is toward even smaller dishes, not more than 1.

The Direct Receive System network consists of more than 4, classrooms spread over the country. The products derived from the image data include: It often has two-way audio interaction component made through a simple telephone line. In addition, space-borne SAR data from Envisat over several test sites during Kharif is being analysed for discrimination and acreage estimation of major crops and to identify the best polarisation combination for optimisation.

Many other projects like inputs for preparation of forest management information system, delimitation of assembly constituencies, etc, have been carried out for Chhatisgarh. To determine distance between two points or how far you are from another location. The five unmanned stations monitor GPS satellite signals and then send that information to the Master Control Station where anomalies are corrected and sent back to the GPS satellites through ground antennas. Simple ground station tracking.

GRAMSAT Satellites: Overview

Each satellite contains several atomic clocks. Satellite television now covers over 65 percent of the Indian land mass and over 90 percent of the population. DTH services were first proposed in India in Auth with social network: Calibration targets have grramsat established at Shadnagar.

State and central government departments, state remote sensing centres and others are associated in these projects. With a synergistic use of the remote sensing and communication capabilities of the Indian satellites, several support services commuunication being provided in the event of disasters.

The activity has been initiated. A portal providing information on NNRMS and metadata of the projects carried out so far has been opened on the internet for disseminating the satellitw to user community. Development of indigenous search and rescue beacons has been taken up and prototypes are being tested. Satellite Communicatkon generally relies on three primary components: We treat Internet in the same way as the other terrestrial networks we provide, and thus offer unrestricted access to this service.

There is no timeconsuming log-on procedure, as users are not required to submit a user-ID or password. Under Phase-II of Agroclimatic Planning and Information Bank taken up for six districts of Karnataka, web-based information bank has been generated for 63 major horticultural crops.
