Gupta, Parmod K.

1992-08-01

Development of microelectronics is taking place at a very fast rate all over the globe, including India. New technologies are introduced at very short intervals in order to capture the consumer market. It is essential that these technologies are managed properly at the macro level in order to bring the desired results. Microelectronics plays a very vital role in office automation for achieving cost effective results in a highly competitive environment. Introduction of various facilities like laser printers, photo copiers, dictaphone-selectronic boards, electronic telexes, teleconference rooms, telephone answering machines, computer, word processors, sensors, etc. have all revolutionized the industry. Keeping the above in view, the present and future status of microelectronics, with special emphasis on its role in office automation in India, are discussed in detail in this paper.

Future mobile satellite communication concepts at 20/30 GHz

NASA Technical Reports Server (NTRS)

Barton, S. K.; Norbury, J. R.

1990-01-01

The outline of a design of a system using ultra small earth stations (picoterminals) for data traffic at 20/30 GHz is discussed. The picoterminals would be battery powered, have an RF transmitter power of 0.5 W, use a 10 cm square patch antenna, and have a receiver G/T of about -8 dB/K. Spread spectrum modulation would be required (due to interference consideration) to allow a telex type data link (less than 200 bit/s data rate) from the picoterminal to the hub station of the network and about 40 kbit/s on the outbound patch. An Olympus type transponder at 20/30 GHz could maintain several thousand simultaneous picoterminal circuits. The possibility of demonstrating a picoterminal network with voice traffic using Olympus is discussed together with fully mobile systems based on this concept.

Effects of the new communication technologies on the structure and the flow of activities in an enterprise

NASA Astrophysics Data System (ADS)

Czaputa, R.

The reported investigation takes into account the developments in a large multinational company of German origin. The worldwide engagement of the company in the areas of development, manufacture, and marketing makes it necessary to maintain close contacts between people in the various branches of the organization. A utilization of all economically employable techniques is needed to satisfy the resulting intensive communication requirements. It is pointed out that the quality of the communication system can be of critical importance because an important order may be given to the firm which can provide information regarding prices and the execution of the order in a shorter time and a better form than competitive firms. Attention is given to the desirability of a further extension of the worldwide telex service, 'electronic mail' in the office, and the transmission of pictorial information.

Kalman filtering applied to real-time monitoring of apogee maneuvers

NASA Technical Reports Server (NTRS)

Deboer, Frederic; Barbier, Christian

1993-01-01

Part of the Space Mathematics Division in CNES, the Flight Dynamics Center provides attitude and orbit determinations and maneuvers during the Launch and Early Operation Phase (LEOP) of geostationary satellites. Orbit determination is based on a Kalman filter method; when the 2 GHz CNES/NASA network is used, Doppler measurements are available and allow orbit determination during the apogee maneuvers. This method was used for TELE-X and TDF 2 LEOP (3-axis controlled satellites) and also for TELECOM 2 and HISPASAT (spun satellites): it enables us to follow the evolution of the maneuver and gives out a quite accurate estimation of the reached orbit. In this paper, we briefly describe the dynamic models of the orbit evolution in both cases, '3-axis' and 'inertial' thrust. Then, we present the results obtained for each case. Afterwards, we present some cases to show the robustness of the filter.

The 'INMARSAT' international maritime satellite communication system

NASA Astrophysics Data System (ADS)

Atserov, Iu. S.

1982-12-01

The history, design, operating characteristics, achievements, and prospects of INMARSAT are discussed. More than 1300 ships are presently equipped to operate within the system, and this number is expected to rise to about 5000 by 1986. The principle of operation involves single coordinating earth stations allocating telephone channels in their zones between other earth stations. The messages reach a common signalling channel with which all ship stations keep in touch. The ship stations are connected to the international telex network. The INMARSAT system enables ships in the automated mode of operation to establish telephone and telegraph comunication with any subscriber on the shore of any country. The quality of the communication is practically independent of the distance between ship and shore at any time of year and under any meteorological conditions. Estimates indicate that the use of satellite communication with ships reduces losses from accidents by 10 percent per year.

Since the initial design phase from 1971 to 1973, the DIOGENE hospital information system at the University Hospital of Geneva has been treated as a whole and has retained its architectural unity, despite the need for modification and extension over the years. In addition to having a centralized patient database with the mechanisms for data protection and recovery of a transaction-oriented system, the DIOGENE system has a centralized pool of operators who provide support and training to the users; a separate network of remote printers that provides a telex service between the hospital buildings, offices, medical departments, and wards; and a three-component structure that avoids barriers between administrative and medical applications. In 1973, after a 2-year design period, the project was approved and funded. The DIOGENE system has led to more efficient sharing of costly resources, more rapid performance of administrative tasks, and more comprehensive collection of information about the institution and its patients.

Computer networking at SLR stations

NASA Technical Reports Server (NTRS)

Novotny, Antonin

1993-01-01

There are several existing communication methods to deliver data from the satellite laser ranging (SLR) station to the SLR data center and back: telephonmodem, telex, and computer networks. The SLR scientific community has been exploiting mainly INTERNET, BITNET/EARN, and SPAN. The total of 56 countries are connected to INTERNET and the number of nodes is exponentially growing. The computer networks mentioned above and others are connected through E-mail protocol. The scientific progress of SLR requires the increase of communication speed and the amount of the transmitted data. The TOPEX/POSEIDON test campaign required to deliver Quick Look data (1.7 kB/pass) from a SLR site to SLR data center within 8 hours and full rate data (up to 500 kB/pass) within 24 hours. We developed networking for the remote SLR station in Helwan, Egypt. The reliable scheme for data delivery consists of: compression of MERIT2 format (up to 89 percent), encoding to ASCII Me (files); and e-mail sending from SLR station--e-mail receiving, decoding, and decompression at the center. We do propose to use the ZIP method for compression/decompression and the UUCODE method for ASCII encoding/decoding. This method will be useful for stations connected via telephonemodems or commercial networks. The electronics delivery could solve the problem of the too late receiving of the FR data by SLR data center.

An Efficient Rapid Warning System For Earthquakes In The European-mediterranean Region

NASA Astrophysics Data System (ADS)

Bossu, R.; Mazet-Roux, G.; di Giovambattista, R.; Tome, M.

Every year a few damaging earthquakes occur in the European-Mediterranean region. It is therefore indispensable to operate a real-time warning system in order to pro- vide rapidly reliable estimates of the location, depth and magnitude of these seismic events. In order to provide this information in a timely manner both to the scientific community and to the European and national authorities dealing with natural hazards and relief organisation, the European-Mediterranean Seismological Centre (EMSC) has federated a network of seismic networks exchanging their data in quasi real-time. Today, thanks to the Internet, the EMSC receives real-time information about earth- quakes from about thirty seismological institutes. As soon as data reach the EMSC, they are displayed on the EMSC Web pages (www.emsc-csem.org). A seismic alert is generated for any potentially damaging earthquake in the European-Mediterranean re- gion, potentially damaging earthquakes being defined as seismic events of magnitude 5 or more. The warning system automatically issues a message to the duty seismolo- gist mobile phone and pager. The seismologist log in to the EMSC computers using a laptop PC and relocates the earthquake by processing together all information pro- vided by the networks. The new location and magnitude are then send, by fax, telex, and email, within one hour following the earthquake occurrence, to national and inter- national organisations whose activities are related to seismic risks, and to the EMSC members. The EMSC rapid warning system has been fully operational for more than 4 years. Its distributed architecture has proved to be an efficient and reliable way for the monitoring of potentially damaging earthquakes. Furthermore, if a major problem disrupts the operational system more than 30 minutes, the duty is taken, over either by the Instituto Geografico National in Spain or by the Istituto Nazionale di Geofisica in Italy. The EMSC operational centre, located at the premises of CEA / DASE in Bruyères le Châtel (France) operates 24 hours a day, 7 days a week. Although EMSC focuses on the European-Mediterranean region, the rest of the world is monitored, but for increasing magnitudes as the distance from this region increases. It generates between 70 to 100 warning messages each year. The utility of this EMSC service is clearly demonstrated by its following among the public : EMSC email dissemination list has been subscribed by about 200 institutions or individuals and there have been, for example, more than 800 connections to our Web site in the 48 hours following 1 the M5.8 earthquake of the Aegean Sea (27/07/2001, alert sent 47 minutes after its occurrence). 2
