This section conducts the static and dynamic experiments of the indoor positioning algorithms mentioned above, and these results are used to find the best indoor positioning algorithm for the RTIPS. To implement the indoor positioning tests, the classroom 5834 of the DAA building of NCKU is chosen as the experiment place. In this paper, the fingerprinting method based on the RSS is utilized to estimate the user location.

The geometry of approximating structures implies the calculus essentially, in particular the mathematical formulae in the algorithms applied in the navigational electronic devices and systems. Thus, we place special emphasis on the geometrical base of the subject.

The Asia-Pacific regional geodetic reference frame, presently characterized as a patchwork of national and regional datums, is below the standard that is now available, and expected, in other regions of the world such as Europe (Bruyninx et al, 2001), South America (Luz et al 2002) and North America (Henton et al 2007).

As the consumer satellite navigation industry continues to evolve, it is interesting to look at the various business models of the industry players and how these drive their market positioning. At a basic level, we see two types of business models currently in the industry. On one side, there are the map providers; a mixture of global and regional/local players and on the other, data-driven technology firms such as Google (Google Maps) and Microsoft (Bing Maps). Whilst the former have expertise in map development and navigation, the latter tend to be stronger in content acquisition and management.

In the book ‘Congo’ (2010), the author David van Reijbrouck reports about the roundtable conference in Brussels in January 1960. There, the Belgian and Congolese delegation agreed on independence of the Congo already in June of that year. From an institutional side, hardly anything was in place in the -soon ‘former’- colony. Executive staff was panicking: ‘how to get a popular census in place in six months, a number plate administration, a cadastre…’.

The dragon moves. And moves faster. Has already sent into the orbit. The 8th navigational satellite. A transition appears. From ‘one of the players’ to ‘the player’. Will set the tone of the future GNSS, And redefine the dynamics, Among various stakeholders in GNSS. With its own stakes, high.

Taiwan releases its first aerial photography drone
A local company has unveiled Taiwan’s first indigenous unmanned vehicle for aerial photography, hoping to break into a market that so far has been monopolized by imported products. The AI Rider, a system based on a six-rotor unmanned aerial vehicle weighing about 1,450 grams, is highly competitive because of its price and after-sales service, including training that is more easily available to domestic customers, said Clark Lin, vice president of Gang Yu Corp.
The remote-controlled aerial photography vehicle is said to be entirely developed in Taiwan and made with domestic components. It can carry a payload, such as a video camera, of up to 400 grams, and can climb to an altitude of 550 meters.
