GNSS Base Station Installation and Data Processing Training Course

 

Regional Centre for Mapping of Resources for Development (RCMRD), Nairobi, Kenya, 30 July - 10 August 2007

 

GNSS/GPS data users have greatly increased in the last few years. However in Africa there is lack of GNSS base stations that could enhance the application and use of GNSS data. Furthermore in Africa, there is no uniform geodetic reference system making maps not compatible and sharing of map information difficult. To overcome these difficulties the AFREF project was initiated by the United Nations for Economic Commission for Africa (UNECA) in 2005.

When fully implemented, AFREF will consist of a network of continuous, permanent GNSS/GPS stations such that a user anywhere in Africa would have free access to the generated data.

The purpose of the course is to provide technical skills in base station installation, data handling and dissemination and precise analysis using scientific GNSS processing software. The qualifying participants shall be Land surveyors, Geodesist, Engineers, Cartographers from African countries with experience in Global Navigation satellite System (GNSS) technologies. Tuition is free but participants have to meet their traveling and accommodation costs.

 

Course contents

·         Introduction to GNSS and IGS data and products

·         Reference systems and frames

·         Requirements of Continuously Operating Reference GNSS Stations (CORS)

·         Operation of AFREF project

·         Theory of GPS data processing

·         Training with Scientific software processing

 

Application deadline: Applications should reach RCMRD at contacts given below latest by 16 July 2007

Symposium on Terrestrial Gravimetry: Static and Mobile Measurements

 

St. Petersburg, Russia, 20 - 22 August 2007.

 

The meeting is being organized by Leonid Vitushkin, Chair of the Study Group 2.1 (Comparison of Absolute Gravimeters) of Commission 2. The symposium is officially sponsored by the IAG, co-sponsored by the Institute of Earth Physics of the Russian Academy of Sciences, Moscow; and the BIPM.

The topics of the conference will include the design and investigations of the measuring instruments for the absolute and relative measurement of the gravity field, their applications for terrestrial, shipboard and airborne platforms, and in the metrology of gravimetry. Traditional free-fall, superconducting, and spring-type gravimeters, gradiometers, and new technologies, such as based on atom interferometry, will be especially welcome, as will results and methodologies of static and mobile campaigns, as well as current and future networks. Geophysical interpretation of results and connection with space-borne systems are of limited interest, since the emphasis is on terrestrial (including airborne) instrumentation and methods to extract gravity field measurements for a variety of applications.

More details about the symposium will soon be available on the website of the meeting. Contact person of the Local Organising Committee is Mrs. Margarita Grishina (mgrishina@eprib.ru).

“Scientific and Fundamental Aspects of the Galileo Programme”

 

2-4 October 2007, Toulouse, France.

 

An international colloquium on fundamental aspects and scientific applications of Galileo and GNSS will be held in Toulouse in October 2007. ANAE (Académie Nationale de l’Air et de l’Espace), Bureau des Longitudes, Académie de Marine and ESA (European Space Agency), are the main instigators of this colloquium meant to contribute to the 50th anniversary celebrations of the launch of Sputnik.

The colloquium will address three major issues:

 

  • The fundamental aspects of navigation by satellites and Galileo: geodetic and temporal reference frames, relativistic frame, on board and ground clocks, orbits, radiative environment in orbit, intersatellite links, fundamental aspects of propagation, tropospheric and ionospheric corrections, calibration and validation, relations with international organisations (BIPM, IGS).
  • Scientific applications in meteorology, geodesy, geophysics, space physics, oceanography, land surface and ecosystem studies, using either normal or reflected signals, differential measurements, phase measurements, occultations, in real or delayed modes, using receivers placed on the ground, in airplanes or in scientific satellites.
  • Scientific developments in physics and dealing with future systems, particularly in testing fundamental laws, in astronomy, in quantum communication, and in developing clocks or experiments based on GNSS.

 

This colloquium intends to bring together leading members of the European scientific community and their international partners. One of its aims is to propose to Galileo partners means of enhancing the scientific use of Galileo and to contribute to GNSS development based on scientific approaches.

Bill Carter and Merri Sue Carter: Simon Newcomb: America's Unofficial Astronomer Royal

 

 

Title: Simon Newcomb: America's Unofficial Astronomer Royal

Authors: Bill Carter and Merri Sue Carter

Publisher: Mantanzas Publishing

ISBN-10 1591138035

ISBN-13 978-1591138037

Year: 2006

Price: US$26.95

Pages: 228 p.

Details: Hardcover

 

Simon Newcomb was one of the most important American scientists of the nineteenth century. He performed his most important work as Director of the Nautical Almanac Office, a branch of the U.S. Navy. He reorganized the theory and means of computing lunar and planetary tables. He was much concerned that different countries published almanacs based on different theories and different values for fundamental constants. He was an early leader in organizing international scientific conferences to address these differences.

In the hands of these authors Simon Newcomb comes alive. There is plenty of source material on Newcomb (the authors mention that the holdings at the U.S. Library of Congress occupy 62 feet of shelf space). Bill and Merri Sue Carter have chosen material that show Newcomb not only as a scientist but also as a man with a family, friends, and scientific colleagues. The reader gets the impression that in their research the authors became quite fond of Newcomb.

Many geodesists know Bill Carter as a leader in the use of VLBI and GPS for geodetic purposes and as an organizer of the International Earth Rotation Service. His daughter, Merri Sue, is an astronomer at the U.S. Navel observatory, studying many of the same problems and technologies as her father. They are also the authors of Latitude: How American Astronomers Solved the Mystery of Variation, which focused on polar motion and the work of Seth Chandler.

Those readers familiar with the early history of the U.S. Coast and Geodetic Survey will find many familiar individuals in this book. Newcomb's wife was Mary (Mollie) Hassler, granddaughter of Ferdinand Hassler, founder and first Superintendent of the U.S. Coast Survey.

In 1856 Newcomb applied for a position with the Coast Survey, which was then directed by Alexander Bache. Unfortunately there were no openings at that time, but J. E. Hilgard, the assistant in charge of the office, was sufficiently impressed with Newcomb's abilities to suggest that he apply to the Nautical Almanac Office in Cambridge, Massachusetts. There he found an entry level position performing numerical calculations. This was a missed opportunity for the Coast Survey. One can only imagine what might have happened if Newcomb's enormous talents had been applied to geodetic problems.

In addition to his hundreds of technical papers in mathematical astronomy, Newcomb was a popularizer of science. Two of his books are Popular Astronomy and Astronomy for Everybody. He even wrote science fiction. For a time he was the person to whom journalists came for understandable explanations of scientific developments. In the same spirit, this enjoyable new book makes the life of this extraordinary astronomer available to a popular audience.
