In a modern mobile mapping system, the navigation component usually consists of a GPS receiver and an inertial navigation system (INS), which can provide accurate geo-referencing to the imaging sensors [1][2]. To achieve centimetre-level positioning accuracy, RTK-GPS is a natural choice. However, RTK-GPS in urban areas suffers from frequent outages due to blockages of either the GPS signals or the reference station radio links. In addition, multipath from buildings, trees and heavy vehicles could degrade the accuracy of the GPS when the vehicle is near them.

GNSS and the GNSS market.
Indicates significant growth.
And immense potential,
In different and emerging application segments
In the world that is developed
And also, that is developing.
The technology is setting a stage.
To change our lives.
In the decade,
That, apparently, belongs to GNSS.
Assuming requisite ingredients
remain available.
May all of us have a happy year 2011.

A metric, Vulnerability Index Against Spoofing, is proposed and used to assess the effectiveness of a spoofer. The GNSS (Global Navigation Satellite System) positioning is known to be vulnerable to interference due to the long distance of radio-signal travel and the resulting low signal power. In the presence of interferences or spoofing, the GNSS navigation performance is likely to be degraded and the navigation function may even be incapacitated. Throughout the years, many GNSS interference mitigation techniques have been developed.

A brief outline of the three segments – User Segment, Space Segment and Ground Segment necessary for
implementation of an SBAS system over the Indian airspace. International Civil Aviation Organisation (ICAO) Member States have endorsed Global Satellite Navigation System (GNSS) as a primary future system for aviation. GNSS provides world-wide coverage for seamless aircraft navigation. Satellite transmission along with ground enhancement will enable the users to perform on-board position determination for enroute, terminal, non-precision and precision approaches.

According to the report……, “Despite significant growth since 2006, significant untapped potential remains.” Would you like to elaborate on this?

According to the forecast based on available information sources and which involved several market experts, the global GNSS revenues are still expected to grow at a double digit CAGR in the 2010 – 2020 period. This growth will come from both new applications and expansion of current products and services. In terms of penetration, the biggest impact will come from LBS since GNSS is still only in a small portion of today’s mobile phones. Regarding new applications, there are countless examples such as ADAS (Advanced Driver Assistance Systems). As for GNSS R&D initiatives in the context of the EU 7FP program of the European Commission, being delegated to the GSA, there is a surge of GNSS technology projects proposing creative applications such as using combined radar and satellite navigation technologies to create maps of coastal areas. Advances in EGNOS and Galileo will accelerate these developments.

The integrity concept, intended as a continuous control of the information broadcast by the satellites, has been introduced by the Galileo system. Though the RAIM technique represents the first example of integrity monitoring, it has the characteristic to detect only local errors, at receiver level. The integrity monitoring applied by EGNOS, instead, could be seen as the forerunner of the Galileo one. Though there are many differences in the definition of integrity of the two system, the main aim is the same for both, that is to protect the user…

From 2006 to 2010, it has been quite a journey for GeoEye. What were the highlights of this incredible journey?
It’s hard to believe how far we’ve come. Just 7 ½ years ago, GeoEye had 60 employees generating $9 million per year, and our equity was worth …
