Magellan introduces its CrossoverGPS
Magellan, enters the consumer driver space with its CrossoverGPS, it caters for road, hiking/off-road and nautical
navigation. It comes with high battery life and with a ruggedised sleeve to protect from drops and the map data comes
from Navteq.

JUPEM is working in tune with new technologies. One of the biggest project is e-Cadastre project. The project has started this year and will be completed by the end of next year. The project envisages a complete digital cadastral database of high quality and integrity. For this purpose, advance techniques and methodologies have been employed like GPS etc.

According to various reports, a significant number of graduates
in India are not suitable for employment.
This is not a happy state of affairs;
We have an education system that is inadequate for skill development.

Since the staring of GPS, many researchers have investigated its application in aerial photogrammetry. Today, with the full constellation of 24 GPS satellites operational, enabling excellent satellite geometry any time of the day, the need to apply the full potential of GPS for real time aircraft navigation and photogrammetric mapping can be realized. The use of GPS to determine relative positional data for ground control points in a photogrammetric block adjustment is widely accepted and practiced. The camera exposure station coordinates derived by Airborne Kinematic GPS drastically reduces, the number of horizontal and vertical control points needed in aerial triangulation.

In large-scale mapping, the accuracy level of control data required is very high. The lag in time between the camera exposure and the GPS epoch recording in the GPS receiver is critical in deriving accurate coordinates for the exposure station (principal point) coordinates. Due to delay in the electronic transfer of data from camera clicking to GPS receiver in recording the event makes the Lag in time to occur. To meet the high accuracy requirements for the largescale photography and mapping projects the lag in GPS recording time should be derived and applied. In this study, an attempt is made to compute the Lag-time in airborne kinematic GPS derived exposure stations from aerial triangulation.

Aerial triangulation is carried in Digital Photogrammetry work station with conventional method of using ground control points, and the exposure station coordinates are derived. Lag-time is computed by finding difference in coordinates of exposure stations derived from conventional aerial triangulation and from airborne kinematic GPS. The results of this project will help to improve the locational accuracy of GPS derived exposure stations in aerial triangulation.
Methodology

Aerial photography is carried out in the study area on 1:6000 scale with forward overlap at 60% and lateral overlap at 20% using RMK TOP30/23 camera. During aerial photography the airborne GPS is operated to record the exposure coordinates.

The computer controlled navigation system (CCNS) is loaded with flight planning data from World Wide Mission Planning (WWMP). During aerial photography CCNS takes coordinates of aircraft position from navigation system and navigate pilot for alignment as per flight plan. Based on navigation coordinates, CCNS sends signals to camera for exposure. The camera exposure system is connected to Trimble 4000 SSI dual frequency GPS system on board, which records GPS data continuously at 1.0sec sampling rate. During the camera exposure, camera system sends signal to the onboard GPS system, which record each exposure as an event marker in the GPS

Last month, New York witnessed cab drivers’ strike.
A protest against a city rule that cabs be equipped with GPS.
Popular contention among others is that GPS is overly intrusive.
It might be possible that such protests are driven by vested interests.
Nonetheless, the privacy issues cannot be ignored.
Many feel that technology is spilling into the zone of …

GPS is overly intrusive
THOUSANDS of cabbies in New York went on strike for two days last month to protest a city rule requiring that all 13,000 cabs get the equipment by year’s end, and among their gripes was that the technology was faulty.
But the new features worked properly 99.21% of the …

THE land-sea interface is one of the most complex areas of management in the world consisting of both the marine and terrestrial environments. The coastal zone is also home to an increasing number of activities, rights and interests. Population along the coastline is continuously increasing, bringing about new pressures on the fragile eco-system of the coastal zone. This has brought with it an increased need to more effectively and efficiently manage this area to meet the economic, environmental and social outcomes of sustainable development.

In particular the comfortable and mobile access to the internet were here the driving factors. Access points can nowadays be found in our daily environment, e.g. in many office buildings, public spaces and in urban areas. Parallel to this development there is meanwhile substantial interest in offering the user information which refers to the current location of the user (so-called Location Based Services LBS). Such Location Based Services, however, will be accepted by the user only if the cost performance ratio is satisfactory. If existing infrastructure such as WiFi without additional hardware installation can be used for location determination, then the realization costs are small and the service can be offered under attractive conditions. Several systems are nowadays available for location determination using WiFi signals. Their major application is the location determination of persons and objects inside buildings.

EC issues Galileo restructuring plan
The European Commission has proposed changes in running and funding the Galileo and Egnos satellite navigation systems, but deferred proposals on procurement competition and private sector involvement. The proposed revamp was recently submitted to the European Parliament and the European Council, which in June agreed to abandon the public-private partnership arrangement that had been set up to manage and fund deployment of the 30-satellite system.
Lack of clear governance was pegged as a major shortcoming of the original managing structure. Under the new setup, the Parliament and Council are to be fully responsible for political and program oversight, the latter through a new European Global Navigation Satellite System Program Committee. The European Commission will act as owner or sponsor of the project, under the supervision of the GNSS Committee.
The European Space Agency will act as prime contractor, under contract to the EC, with responsibility for the In Orbit Validation (IOV) spacecraft, the 26 Full Operational Capability (FOC) satellites and the related ground segment. The agency will report regularly to the Parliament and Council on program progress. The GNSS Supervisory Authority (GSA), which had been created to manage negotiations with the private sector under the original public-private partnership scheme, was given a new job. The GSA will be beefed up and made responsible for preparing market services, handle accrediation/certification, and serve as advisor to the Commission.
The EC determined that the cost of building and deploying the system would not exceed 3.4 billion euros ($4.7 billion) – in line with earlier estimates – provided that there are no further delays or major changes in procurement policy. www.aviationweek.com
