It is sometimes suggested that spatial data is just another form of data that can now be maintained in a data base and that in reality there is nothing “special about spatial”. Nothing could be further from the truth. For example spatial data is not the same as integer, alphanumeric or symbolic data for a number of reasons. These are: spatial data is scale dependent: do I query for 37.3N 45.2W..or? spatial queries are endemically computationally expensive…
For the final evaluation of a GPS attitude determination algorithm (GADA), it was determined its true performance in terms of its accuracy, reliability and dynamic response. To accomplish that, a flight test campaign was carried out at the Brazilian Flight Test Division (GEEV) to validate the attitude determination algorithm. In this phase, the measured aircraft attitude was compared to a reference attitude, to allow the determination of the errors…

The GNSS Research and Application Centre of Excellence (GRACE), is a cross disciplinary centre providing cutting edge research, high calibre teaching, and business support services to the GNSS community. In October 2009 GRACE will move into its own state-of-the-art purpose built centre. A ground breaking ceremony took place on the 11th of November 2008, and construction of the centre is underway at the University of Nottingham Innovation Park (UNIP) on the Jubilee campus of the University of Nottingham.
It will be the only facility in UK dedicated to the development of downstream applications and services using GNSS. The European Union has estimated the market for downstream applications and services to be worth in excess of £230 billion by the year 2025. Supporting the University of Nottingham in this venture which will have an investment of £9.2m is the East Midlands Development Agency (EMDA), one of the nine regional development agencies in England. EMDA was established in 1999 with the primary goal to increase the economic growth of the East Midlands region.
