Four times GNSS

A Worldwide Race
The Munich Satellite Navigation Summit opened during the first week in March 2009 with a plenary session entitled ‘The Worldwide Race in GNSS’ and closed with a panel discussion on the subject of ‘competition among the Big Four’. Although several speakers did their best to convince attendees that there was no race or competition, it is obvious that four systems serving the same market will be involved in a race for the best technical solutions and engage in fierce competition. If it is indeed a race/competition, let us have a look at the score so far. GPS Since 1978 this... (read more)

Integrating GNSS and INS

GNSS provides accurate positional information with relatively low integrity, while INS offers position and attitude information subject to drift but with relatively high integrity. Integrating the two provides reliable and accurate information on position and attitude of vehicles on land, at sea, in the air and in space. Integrated GNSS/INS: I know what it is, I know what it does, but how does it work? All sensor data such as aerial imagery acquired from an airborne platform needs to be geo-referenced to be of further use. In treating the subject of exterior orientation we here focus on aerial digital cameras,... (read more)

GNSS for Sea Trials

Measuring Ship Controllability
The effective seakeeping performance of any watercraft is vital for safe navigation. Due to the long maritime tradition in Greece, the National Technical University of Athens (NTUA) has been a key player in developing tools and practices for conducting sea trials in open water. Since the introduction of the Mini-Ranger many years ago through to the recent introduction of the modern GNSS sensors, a number of new-built and commissioned surface ships of various sizes have been tested either in the interests of the shipbuilder or the owner. Currently, new navigation tools and techniques are being set in place to fulfil... (read more)

GNSS: Evolution or Revolution

Four Questions on the Status of GNSS
The market for Global Navigation Satellite Systems (GNSS) has never looked so buoyant. Are we in the midst of a revolution or simply witnessing evolution pre-planned and destined to run its course? Two fictional respondents, the revolutionist and the evolutionist, here answer four pertinent questions.<P> GNSS applications are becoming mainstream and available in a growing number of devices. And improvements in the signals via new satellite systems and new technology such as secure user plane (SUPL) for wireless devices will improve reliability and functionality. Everyone would agree that there is a lot going on in GNSS. This is manifested in... (read more)
