The paper presents the current and uniform approaches to sailing calculations highlighting recent developments. We published the first part of the paper in May 11. Here we present the concluding part.

The use of a semi dynamic datum has been well accepted and its implementation and use have been relatively straight forward from a technical and geodetic perspective.

Says, Mr. Alexander Wiechert , Business Director, Vexcel Imaging GmbH in coversation with Coordinates.The UltraCam was conceived by Vexcel Imaging prior to the acquisition of the company by Microsoft. The organization, now known as the Microsoft UltraCam product group, has a history of leading the industry by innovation.

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.

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.
