Says, Dr Dru Smith, Chief Geodesist of NOAA’s National Geodetic Survey while explaining the GRAV-D project

What is the GRAV-D project?
GRAV-D stands for “Gravity for the Redefinition of the American Vertical Datum”. It is a multi-year project designed and led by the National Geodetic Survey (NGS). GRAV-D was initiated to measure and monitor …

The Ministry of Civil Aviation, Government of India has the sovereign authority to modernize the Indian Airspace. Rapid strides have been made by the Ministry of Civil Aviation in implementing many elements of the Global Air Navigation Plan recommended by the International Civil Aviation Organisation (ICAO) for Communications, Navigation, Surveillance (CNS)/Air Traffic Management (ATM) systems. India is a founding member of ICAO and is a regional member of the ICAO Asia Pacific Air Navigation Planning …

This paper describes the performance improvement of GPS/DR (Global Positioning System/Dead Reckoning) Integration system utilizing the area decision algorithm and vehicle movement information. In GPS/DR Integration system, generally DR sensor errors are estimated and corrected using GPS information when GPS is available. In GPS signal blockage area, i.e., tunnel and underground parking area, DR sensor errors are accumulated and navigation solution is diverged eventually. We utilize the car movement…

For all the three pillars of space geodesy (the geometry of the Earth surface and its displacements, the orientation of the Earth axis and its rotation speed, and the Earth’s gravity field and its time variations), well-defined, highly accurate and stable global Earth-fixed and celestial reference frames are of primary importance. Over the last decade considerable changes took

The integration of navigation and communication functionalities is one of the key elements exploited in new location-based systems and services

GNSS technologies are progressively becoming one of the key elements in most of innovative wireless applications. Most location-based services and systems are in fact …

Global Positioning System (GPS) provides precise timing, position, and velocity information by utilizing the constellation of satellites and a remote receiver that uses range measurements to the satellites and spatial trilateration techniques. In addition, more navigation satellite systems including Russia’s GLONASS, Europe’s Galileo, and PRC’s Compass will be available for the coming years. Those systems will form the mainframe of future Global Navigation Satellite System…

After the euphoria over the successful Chile mine rescue it is time to analyze the incident and ponder on the lessons learned.

Mines and accidents have been intertwined since time immemorial. But the Chile mining accident has become a watershed. Not because of the accident itself – this was no different from the many that have …

says Paul Verhoef Programme Manager, EU satellite navigation programme, European
Commission, Brussels, Belgium while emphasising on the difference between Galileo and
other GNSS systems

What is the status update on Galileo and in what stages will it become operational?
We are currently defining our initial operational capability (IOC) in detail.
Initially some services will be available which will not …

Compass and Galileo.
Apparently heading for a ‘head on’,
On frequency and signal issues.
In a world of multi GNSS systems,
With different priorities and agendas,
Such differences are inevitable.
But we do need a compatible and interoperable environment.
At the same time, we do live with conflicts and coexist.
Don’t we?
