free, but interested audience should register in advance by sending registration email to This email address is being protected from spambots. You need JavaScript enabled to view it.

Abstract: The main problem we face when developing a radio-based indoor positioning system is the environment's heterogeneity. Not only does this heterogeneity have an impact on the radio waves' propagation, but the environment itself evolves, on several time scales, making it difficult to predict the waves' characteristics.
Owl Positioning System (OwlPS) is an indoor positioning system based on the IEEE 802.11 (Wi-Fi) standard, developed at the University of Franche-Comté, France. It features a self-calibration (or autocalibration) mechanism, allowing the avoidance of a tedious manual calibration of the system, but above all the ability to take into account the radio environment variations in real time. This talk will be articulated into three main parts:

  • An overview of indoor positioning basics, and especially of the radio-based indoor positioning techniques.
  • A detailed presentation of the OwlPS system.
  • The self-calibration mechanism implemented in OwlPS.

From 1-3 August, 2012, in Hue City, in collaboration with the ICCE 2012 conference, NAVIS Centre organised the Special Session on Satellite Navigation Technology. The Session has 6 full paper accepted out of 14 submissions from Vietnam, Italy, France, Spain, USA; together with 2 keynotes from Prof. Andrew Dempster - University of New South Wales - Australia and Prof. Gabriella Povero (Growing NAVIS project and ISMB - Italy).
The Session started in the 2nd day of the conference with two sub-sessions chaired by Prof. Letizia Lo Presti - Politecnico di Torino, Italy - and Prof. Andrew Dempster. There have been many interesting discussions among participants during the Session, which promises fruitful cooperation in future.

Also the Session was a very good chance for Growing NAVIS people to discuss and exchange ideas cum results of their research in the framework of the project. Thanks to the organisers, session-chairs, technical program committee, presenters and participants for the success of the Session.

Participants of the Workshop and distinguished delegates from UNSW, HUST, Growing NAVIS

Right after the ICCE Special Session on Satellite Navigation, in Hanoi, from 6 to 8 August 2012, NAVIS Centre with the support of The University of New South Wales (UNSW) and in cooperation with the Growing NAVIS Project, organised the "Workshop on Radionavigation and GPS Technology”. The Workshop has attracted 85 registered participants. Apart from Vietnamese, there were 7 international participants from Thailand, Malaysia, Sri Lanka and Pakistan. The participants come from academia, industry, national and international organisations with their expertise covering the fields of ICT, electronics, remote sensing, aerospace, aerial control, maritime, mechanical etc.

The opening ceremony of the Workshop had the presences of Prof. PHAM Hoang Luong - Vice-President, Mr. Hoang Xuan Lan - Director of Department of International Cooperation, Prof. Dinh Van Phong - Director of Department of Science and Technology and other directors and school deans of Hanoi University of Science and Technology (HUST). On behalf of HUST, Prof. Hoang Luong has stressed the important of such an event in Vietnam. He also thanked UNSW, Growing NAVIS project for bringing this Workshop to Vietnamese research community and strongly believes that with the supports of the international partners, HUST and in particular its NAVIS Centre will have a big chance to be an international recognisable research centre in the field of satellite navigation not only in Vietnam but also in South East Asia.

In turn, Prof. Andrew Demspter thanked HUST for organising this Workshop and hoped that this is the starting point for the fruitful cooperations between the two Universities in satellite navigation. On behalf of Growing NAVIS project, Prof. Gabriella Povero stressed that this Workshop is the first education and training activity of the project, and from 2012 to 2014, there will be 3 other workshops in Malaysia, Thailand and Vietnam and a summer school next year in Vietnam, which definitely will contribute significantly to the development of satellite navigation in the region.

During 3 days, participants were provided with 16 topics covering fundamental and advanced knowledge in satellite navigation technology as well as experimental experience with NAMURU receiver developed by UNSW.

Below are some pictures of the Workshop.
