PROGENY Pilot Project in Thailand

On November 21-22, Fabrizio Dominici and Davide Margaria presented the SAT-SURF & SAT-SURFER solution at the Asian Institute of Technology (AIT) of Bangkok. The two days workshop was carried out under the Progeny project (funded by the European GNSS Supervisory Authorithy) and organized by ISMB and AIT with the support of Prof. Nitin K. Tripathi and Prof. Kiyoshi Honda. The seminar has been attended by 45 students from AIT.

DAY 1: The day started with an introduction of the NavSAS Group research activities. In particular it has been showed the background for the SAT-SURF & SURFER realization, providing also an overview of the NAVKIT. Moreover in the morning the presentation included details about architecture, functionalities and application fields for both the hardware and software platforms (SAT-SURF & SAT-SURFER). The morning session has been concluded with the setup and configuration of the demonstration platform with a quick view of the main features previously described. In the afternoon it has been faced the first data collections and the solution of some exercises provided with SAT-SURFER.

DAY 2: The exercise session has been concluded in the second day proposing additional exercises and providing the solutions. The students have been also assisted for the setup and configuration of the educational platform on their PC. The seminar ended with a fill out of the tutorial evaluation questionnaires and an open question session for deepening on SAT-SURF & SAT- SURFER.

We hope that the positive feedbacks and the useful suggestions received by the students can feed the discussion on this blog and help to learn how to practically SURF with GNSS!!!

Sat-Surf & Sat-Surfer Suite brought to life!

Education on GNSS topics is sometimes difficult and often lacks of practical experience. In order to train students and professionals to face real issues and manage satellite navigation data, the NavSAS group developed Sat-Surf and Sat-Surfer: the Training Board & the Software Suite for GNSS Training!
This solution includes hardware and software facilities as well as practical exercises. It is dedicated to the GNSS students but it can be also useful for all the professionals in the field of navigation.

For a complete GNSS training the theory is provided by the NAVKIT distance learning tool, and the practical skills are trained by means of the Sat-Surf & Sat-Surfer suite. The Sat-Surf is a compact, lightweight and versatile device able to accommodate different GPS receiver. It can embed different kinds of GPS receivers, such as: the new uBlox5 Galileo Ready, the uBlox – Antaris4, the Falcom JP13 LP based on SiRF Star III technology and the Falcom JP15 based on SiRF Star II. In the next months the platform will be adapted to accommodate also other chipsets.

Sat-Surf includes communication capabilities using a GSM/GPRS quad-band unit that enables the development of innovative A-GPS strategies as well as the study of DGPS techniques.

The Sat-Surfer software thanks to its flexibility allows the interface to the Sat-Surf and includes the possibility of data collection and storage.Hardware and software are complemented by a set of proposed exercises, included in the package, that ranges from a simple level of usage, to an advanced for development of original navigation algorithms for data processing.

NavSAS at the GNSS Summer School

Here is the report of the first day at the Second International Summer School on Global Satellite Navigation Systems by Gianluca Falco, a NavSAS Ph.D.

After a long trip, finally I reached Berchtsgaden, a quite small village close to the Bavarian Alps that is the established site for the GNSS summer school. Few minutes after my arrival, I had the chance to meet some participants to this school. They come from a lot of countries spread all over the world: Germany (of course), Belgium, Austria, Denmark, Poland, Romania, Russia, also outside Europe such as Brazil, Australia, USA, and even from Rwanda! I spoke with lots of them: four of them work for Septentrio company in Belgium, other guys work for DLR (German Aerospace Agency) testing GNSS system. Then I talked with Russian guys that work for the Russian Space Agency in Moscow (of course the navigation system they use is GLONASS).

At 6 PM professor Guenther Hein started the opening ceremony.
He provided us an overview of what we'll do in the next ten days of the school, speaking about the content of the lectures we'll follow. A very interesting topic of his speech is that we'll have the chance to receive and test a real Galileo signal computing the user's position thanks to three pseudo-like satellites set up on the top of the mountains nearby Berchtsgaden.

Then he introduced three other famous professors: Prof. Per Enge of Standford University, Prof. Michel Bousquet of ISAE (French Aerospace Engineering Institute) and Prof. R. Grohe of the Technical University in Aachen.

Then we moved to the Congress Hall to follow a lecture given by Thomas Reiter, a former astronaut for ESA who experienced twice how life in space is. In fact he was on board engineer for the Euromir mission in March 1995 when he spent 179 days on board of the space station. Then a couple of years ago he took part to the Astrolab mission, the first European long-term mission on board the international space station. During this lecture he showed us some videos about life on board a space station and what are the tasks that each astronauts has to fulfill every day to maintain a right working of the space station. Then he explained us that a lot of experiment were made inside the space station: biologic ones (about the study of the growth of some vegetables and to make them more robust against disease), tests about plasma particles (used for example to manufacture more advanced semiconductors) and, last but not least, lot of tests on human beings focused, in particular, on heart check up.

NavSAS Mid Term meeting.

Yesterday the NavSAS group had the Mid Term plenary meeting. It has been a chance to verify the personal and team objectives foreseen for the 2008.

The meeting aimed also at sharing among people of the NavSAS who work on different sub-topics the milestone achieved by everyone, sharing some of the good results, and also the weaknesses still to be improved.
Any weakness is in fact also an opportunity.

There are still 6 months for everyone to achieve the year's objectives. Now back to work !!!!

NavSAS at the International Training Course in India

Prof. Letizia Lo Presti and dr. Beatrice Motella are currently in Ahmedabad India teaching some lesson at the International Training Course on satellite navigation and location based services.

The course is held at the United Nations- affiliated Regional Centre for Space Science and Technology Education in Asia and the Pacific (CSSTEAP), in Ahmedabad, India.


This Training Course is co-sponsored by the Government of the United States of America through the ICG and organized by the UN-affiliated Regional Centre for Space Science and Technology Education in Asia and the Pacific (CSSTEAP) and will make a major contribution to capacity building in the use of GNSS in various areas of applications.

The UN-OOSA states that this is the first activity in a series of training courses to be organized in the field of GNSS applications in UN-affiliated Regional Centres, and will start the development of a model education curriculum in GNSS supplementing the already existing four education curricula in space science and technology. This is also the first activity to pursue the prospective acting of Regional Centres of Excellence as ICG Information Centres.
