Navteq Plan Skirts Vehicle-Install GPS Navigation

2008-10-21T14:46:00.000+01:00

Digital map and location-based services provider Navteq has unveiled its Map and Positioning Engine (MPE) strategy, which includes plans to offer map-enabled driver assistance on cars without installed navigation systems or navigable maps.

Outlined at a trade show in Paris this week, the subsidiary of cell phone maker Nokia (NYSE: NOK) said the strategy calls for its MPE product to deliver map-enhanced Advanced Driver Assistance System (ADAS) applications that will be embedded directly in the electronic control units of vehicles. The low-cost technology can be implemented on credit card-sized circuit boards or even distributed in vehicles' electronics architecture.

"The map and positioning engine reference solution is a fundamentally new way to think about digital maps and GPS positioning in the vehicle electronics architecture," said Bob Denaro, Navteq's VP of ADAS, in a statement. "The industry needs a solution that brings the value of digital maps and vehicle positioning to all vehicles."

Ever since Nokia's $8.1 billion acquisition of Navteq was approved earlier this summer, the automotive and wireless phone industries have been waiting to hear how Navteq would approach the Internet-based mapping market.

Navteq's MPE specification contains the company's Electronic Horizon algorithms, which enable the searching and interpreting of the road ahead. Unlike traditional ADAS, the Navteq application is always on and requires no stored navigation route.

Navteq, which has 194 global offices, indicated that its tech and customer support staff will be available to help customers use the algorithms with its maps.

The application and development of GPS in transportation

2008-10-15T17:53:00.001+01:00

The solution geographic information system is the collection modern computer science, the geography, the information science, the management science and the survey science is a body's emerging discipline. It uses the database, the computer graphics, multimedia and so on newest technology, carries on the data processing to the geography information, can real-time gather, the revision and the renewal geography spatial data and the attribute information accurately, provides the visualization for the policy-maker the support (1). At present in many domains, the GIS technology has been widely applied. Especially in the transportation domain, GIS and the traditional transportation information analysis and the processing technology unified closely, extends the transportation geographic information system (Geographic InformationSystem for Transportation), was called GIS-T.

1 GIS outlined GIS most to get up early stems from the 1960s “to turn the map the digital form the map, was advantageous for the computer processing analysis” goal. in 1963, Canada surveyed scientist R.FTomlinson first to propose GIS this terminology, and used in the natural resource the management and the plan. Among afterward several dozens years, were following the computer technology and the networking rapid development, the GIS application also day by day deepen and widespread, in domains and so on environment, resources, petroleum, electric power, land, transportation, public security, aviation, municipal administration management, urban planning became the standing-by work system. GIS is technical and so on graphic processing technology, visible technology and database organic synthesis, and establishes a new school by its blended data structure and the formidable geography spatial analysis function. It (database management system) and so on has the very big difference with the CAD system and DBMS. Although the CAD system has the formidable graphic processing ability, but its analysis situs relations are quite simple, the management and analysis large-scale geography database's ability is also limited; DBMS stresses in the non-graphic data optimization saves and inquires, but the graph inquiry, the demonstration function, the data analysis function relatively is weak. It is well known, in GIS the most foundation is also the most important part is the geography data. GIS can realize to the massive complex geography data input, the memory, the operation and the analysis, the output and so on a series of functions. Input: The GIS data majority from the real world, the data quantity is quite big. At present the data feeds method which widely uses is the traditional manual digitized method. At the same time, the remote sensing data is becoming the GIS data day by day the important origin, this symbolizes that the GIS data feeds already started with the aid in the non-map form. Moreover, the GPS technology mature also promoted the GIS data acquisition technology development day by day. Memory: GIS is quite unique to the data memory, namely has used the lamination technology generally in the majority GIS systems, therefore user when saves these data, is only processing involves the level, but is not the view picture map, can thus make the rapid reaction to user's request. Operation and analysis: GIS has inherited CAD and the DBMS graph operation and the data processing mature technology fully. In GIS the spatial data and the attribute data have the close relation, is high to the data uniform request, and GIS has the formidable spatial analysis function to the geography data. This is the GIS essence is, is also the GIS technology can in many domains the widespread application key. Output: GIS can by the appropriate form output user inquiry result or the data analysis result. Regarding the output accuracy requirement high application domain, may using the data correction, the edition, the graph retouch, technologies and so on error cancelling, coordinate transformation to improve the output quality. Because in GIS data processing is quite tedious, the work load is big, already was completely unable through the manual way to meet the current need, must therefore use computer's handling ability fully, with the aid of assists in the software system to complete these work. At present the GIS domain quite mature software has American ESRI Corporation's Arc/Info, Mapznfo Corporation's MapInfo, Intergraph Corporation's MGE and so on.

In recent years, along with geographic information system's swift development, more and more application domains has established the close relation with the GIS technology. Because the transportation information system has the accuracy requirement to be high, the rule is complex, discretization characteristics and so on tendency, the original information technology already could not satisfy the transportation application completely the demand, but with the aid in the GIS formidable function, may realize the transportation informationization time request. In the transportation domain the GIS application also more and more receives the researcher and exploiter's value. The transportation geographic information system is the collection, the reorganization, the memory, the management, the generalized analysis and the processing spatial information and the transportation information computer software and hardware system (2), is the GIS technology in transportation domain extending, is GIS and many kinds of transportation information analysis and the processing technology integration. GIS-T has the formidable transportation information service and the management function, it may apply in traffic control each link. Uses the GIS technology and the method study transportation plan, the transport facilities and the traffic control and the related question in the traffic engineering domain, has the other conventional routes incomparable merit. In the 1960s, the US Bureau of Vital Statistics has established DIME as well as afterward TIGER data model, at that time they have used express the road system based on and the line univariate linear network. In these with the line between two points connected attribute list, has recorded line between two points each kind of attribute information. , This kind of pattern has been since the road traffic system expresses the model a mainstream. But along with social and the economical development, the road traffic system becomes day by day complex, is getting higher and higher to the transportation geographic information system's request, GIS-T will face more challenges. 3 GIS-T key technologies GIS-T improved GIS and TIS (transportation information system) marriage. At present are many researchers to devote to the GIS-T research and the development, revolved GIS-T to have the many research subjects, the different research subject involved the GIS-T function also had the difference. In order to carry on the detailed explanation, may through define 3 function groups to obtain an general frame, these 3 function group is: The data management (realizes data storage and maintenance), the data manipulation (realizes the model which primary data's innovation), the data analysis or the establishment may analyze. They are the interdependence support mutually, the data storage is the data manipulation premise, but the data modelling is also establishes in the first two foundations. 3.1 database management system since long, the Traffic department must use and maintain the massive information, in many situations is many transportation information system coexistence in the identical department, moreover each transportation information system can only process some class number according to what is believed rest (for example highway plan network, highway administration system as well as accident information and so on). The GIS-T data management system's key technologies lies in through the establishment data model and the data exchange frame, the above different data storage in a unified data management system, any department can visit in this system to conform to the data which this department requests, simultaneously can carry on the analysis and the modelling to these data, then carries on the management and the decision-making.

Determine the location of data collection

To a point on the celestial sphere determine the location of the celestial sphere on the establishment of the spherical coordinate system. There are two basic elements:

① basic plane. By the celestial sphere on a selected set by the great circle. Known as the great circle of laps, the two-lap as a spherical geometry is one of the very coordinates.

② the main point, also known as the origin. Selected by the celestial sphere on a pole of the coordinates of the great circle and the circle of the intersection identified.

Tian Tian at this point in the coordinates of the location of the two spherical coordinates calibration:

① coordinates or the first to coordinate. Made the point and the coordinates of the great circle of the pole, said Deputy laps from the main point to the vice-circle and circle the arc length of the intersection to coordinate.

② second latitudinal coordinates, or coordinates. From the circle-on effect along the circle to the point of the great arc for the latitudinal coordinates long. Any point on the celestial sphere can be the location from which to identify only two coordinates. This spherical coordinate system is orthogonal coordinates. For different circles and the main base, and to coordinate the different measurements used by the way, leads to a different celestial sphere coordinates, a commonly used amlodipine coordinates, the equatorial coordinate system, the ecliptic coordinates and coordinates Silver Road

GPS prospects

2008-08-27T18:36:00.000+01:00

As GPS technology with the all-weather, high-precision measurement and automatic features, as an advanced means of measuring productivity and new, have been integrated into the national economic construction, national defense construction and social development of various applications.

With the end of the Cold War and the global economy booming, the U.S. government announced the 2000-2006 period, in ensuring national security is not threatened the United States, under the premise of the policy cancellation SA, GPS civilian signal precision on a global scale to improve and use of C / A code of conduct point positioning accuracy from 100 meters to 20 meters, which will further promote the application of GPS technology, increasing productivity, operational efficiency, scientific level and quality of life and stimulate the growth of GPS market. According to experts predict that in the United States, alone automotive GPS navigation system, in 2000 after the market will reach 3 billion U.S. dollars, while in China, car navigation market will reach 5 billion yuan. This shows that, GPS technology market prospect is very impressive.

GPS Frequencies

L5 (1176.45 MHz): Proposed for use as a civilian safety-of-life (SoL) signal (see GPS modernization). This frequency falls into an internationally protected range for aeronautical navigation, promising little or no interference under all circumstances. The first Block IIF satellite that would provide this signal is set to be launched in 2009.

GPS History

2008-08-20T13:59:00.000+01:00

The basic idea to build up a navigation system using satellites already existed before World War II. In May 11, 1939 the German aerospace scientist Karl Hans Janke announced in Berlin a patent for a "Position indicator concerning to aircrafts“ which had been issued on November 11, 1943.In the patent, he assumed two distant bodies (satellites) which are permanently sending electromagnetic signals. Those signals can be received and be shown on a screen as a vector. By laying a map on that screen it would be even possible to determine origin and direction of an object.

The design of GPS is based partly on similar ground-based radio navigation systems, such as LORAN and the Decca Navigator developed in the early 1940s, and used during World War II. Additional inspiration for the GPS came when the Soviet Union launched the first Sputnik in 1957. A team of U.S. scientists led by Dr. Richard B. Kershner were monitoring Sputnik's radio transmissions. They discovered that, because of the Doppler effect, the frequency of the signal being transmitted by Sputnik was higher as the satellite approached, and lower as it continued away from them. They realized that since they knew their exact location on the globe, they could pinpoint where the satellite was along its orbit by measuring the Doppler distortion.

The first satellite navigation system, Transit, used by the United States Navy, was first successfully tested in 1960. Using a constellation of five satellites, it could provide a navigational fix approximately once per hour. In 1967, the U.S. Navy developed the Timation satellite which proved the ability to place accurate clocks in space, a technology the GPS relies upon. In the 1970s, the ground-based Omega Navigation System, based on signal phase comparison, became the first world-wide radio navigation system.

The first experimental Block-I GPS satellite was launched in February 1978.[4] The GPS satellites were initially manufactured by Rockwell International (now part of Boeing) and are now manufactured by Lockheed Martin (IIR/IIR-M) and Boeing (IIF).
