Today, mobile devices are not only tools for the communications but also personal assistants. People could use the mobile device built-in Global Positioning System (GPS) receiver to search for information based on his/her location, thus called Location Based Service (LBS). However, due to the GPS signal propagation limit, the positioning and navigation services are discontinued when the user enters the indoor environments. When users are in the indoor environments, how to continuously obtain their locations becomes a popular research topic.

Recommendations of the National Commission on Urbanization (NCU), set up in 1985, covered the aspects of emergence of nodal points; special regional characteristics of urban growth; spatial eco-tones of urbanization; spatial distribution of wheat and rice productivity and industrial employment; and spatial planning of settlements . Besides other analysis, it studied the spatial distribution of cities and urban agglomerations in 1971 and 1981 .

The USA moves ahead with GPS III.
China takes a leap forward with five satellites of COMPASS last year.
And promises four more this year.
GALILEO appears for a compromise of 18 satellites as of now.
And Japan assures of a steady progress with MICHIBIKI in place.
GLONASS suffers a massive setback with of loss of three satellites.
But the zeal continues with GLONASS K in place.
Many such voices were made and heard.
At recently held Munich Satellite Navigation Summit in Germany.
And also was heard.
A loud silence on Indian Regional Navigation Satellite System.

Whenever there is a need for continuous navigation, radio-technical systems are usually integrated with inertial navigation systems (INS) or dead-reckoning systems (DR). Due to large dimensions and power consumption, as well as high prices, INS systems have been traditionally applied in high-end or military applications. Recently an unprecedented decrease of all the above mentioned factors have been witnessed, making inertial navigation suitable for a wider set of applications. However, the dead-reckoning method is still the preferred choice in low-cost land navigation systems.

The Indian Naval Hydrographic Department, with its rich traditions in the field of hydrography, wide ranging experience, a good infrastructure coupled with an excellent Human Resource, has the entire requisite wherewithal to be ranked amongst the best in the world. This has not happened overnight; the initial foundations have been laid by our predecessors and we who man and run the department now have been blessed by a good beginning. In the last five years, we have only added on to its already established stature.

In the so called Tri-Valley Universityí in California, USA.
Students were allegedly duped and framed.
Now, tagged with GPS ankle-bracelets.
By the officials of Immigration and Customs Enforcement.
Why so?
