Successfully using Beidou navigation service in NAVIS Print Email

Since December 27, 2012, the Beidou Navigation Satellite System officially started to provide the free civil navigation service to users in the Asia - Pacific region. After the official statement, we started to develop our first Beidou receiver, which is also among the firsts in the world. 

The Beidou Navigation Satellite System is a Chinese satellite navigation system. It consists of 2 separate satellite constellations-a limited test system that has been operating since 2000 and a full-scale global navigation system that is currently under construction. The first Beidou system, officially called the Beidou Satellite Navigation Experimental, in the period development, the system consists of three satellites. It provided navigation services for customers in China and neighboring regions, since 2000. The second Beidou system was initiated in 2004 and it became operational in China and neighbor countries in December 2011 with 10 satellites in use[1], and began offering services to customers in the Asia-Pacific region in December 2012. The third generation of the system will be developed continuously and available by 2020 with the global coverage capability.

With the objective of developing a multi-GNSS receiver, which could operate with all GNSS systems available, we started to work with Beidou signal right after the announcement from the Chinese goverment about the availability of the Beidou navigation signals. Our Beidou receiver, which is a part of the multi-GNSS NAVISOFT receiver, is now sucessful in decoding the E2-I civil signal, demodulating both the D1 and D2 types of navigation messages, and eventually computing the position, velocity and also timing results. Below are some figures of important signal processing blocks of the receiver:

Fig. 1: Results of (a) signal acquisition; (b) signal tracking and data demodulation; and signal power measurements

Fig. 2: Position computation results: yellow pins - computed positions; red pin - true location of the antenna on top of the Ta Quang Buu library building

This Beidou receiver contributes an important part to the NAVISOFT receiver developed by NAVIS. NAVISOFT works with not only all GNSSes (i.e. GPS/GLONASS/Galileo/Beidou) but also QZSS, which is a regional system of Japan and also broadcasts augmentation data for improving GNSS positioning. More importantly, beside stand-alone mode, in which each system operates independently, NAVISOFT also supports the real combined multi-GNSS mode, in which all satellites in view from all systems are utilized to provide a common positioning and navigation solution. Fig. 3 shows the sky plot of all satellites in view and combined positioning results reported by NAVISOFT:

NAVIS visits Torino for ICL-GNSS 2013 and G-NAVIS midterm review Print Email

From 25 June to 3 July 2013, the representative of NAVIS, Dr. Ta Hai Tung, visited Torino, Italia for the International Conference on Localization and GNSS (ICL-GNSS 2013); the mid-term review of the Growing NAVIS project; as well as several research exchange activities with the NAVSAS laboratory at ISMB.

Dr. Tung was presenting at the ICL-GNSS 2013

At the ICL-GNSS 2013, Dr. Tung presented a paper titled: "Recent results in receiving and decoding signals from the Beidou system" co-authored with Truong Minh Duc, Tran Thanh Trung and Nguyen Dinh Thuan. The paper presents the research results of NAVIS on Chinese Beidou Navigation System, which has just broadcasted services to users in Asian - Pacific region since December 2012. At this moment, outside China, there are not mass-market Beidou receivers. The paper will be soon available on the IEEE Xplorer.

After the ICL-GNSS 2013, Dr. Tung also attended the midterm-review of the Growing NAVIS project. During the session, all WP leaders of the project presented the results in the first half of the project's life. Ms. Justyna REDELKIEWICZ MUSIAL, the representative of European GNSS Agency, also attended the review over teleconference from Prague. The review was succesful, which showed the quality of the acitivities carried on by the Growing NAVIS consortium. NAVIS, as a focal point of the project, will surely grow up with those results.

Discussions on research cooperations at ISMB

A part from the conference and the review, Dr. Tung also took the opportunity to have several important discussions with NAVSAS group at ISMB, and especially with the Joint Research Centre (JRC) of European Commission. Some important discussions with NAVSAS and JRC were conducted, which promise a fruitful research cooperations on satellite navigation among NAVIS, NAVSAS and JRC, especially in the field of ionospheric monitoring, which is now catching the great attention of the GNSS community. Located near the equator where the ionosphere anomaly is visible and not well understood, NAVIS can play an important role in doing research in this field.
