ENCORE: Enhanced code Galileo receiver for land management applications in Brazil

Abstract

Taking benefit of the new Galileo ranging signals, the ENCORE (Enhanced Code Galileo Receiver) project aims to develop a low-cost Land Management Application to cover needs of the Brazilian market in terms of geo-referencing and rural/urban cadastre, using a low-cost Enhanced Galileo Code Receiver as baseline. Land management applications require precision and accuracy levels from a few to several decimetres that are under-met with current pseudorange-based receiver and over-met with phase observations. This situation leads either to a waste of resources, or to lack of accuracy. In this project, it is proposed to fill this gap using the new possibilities of the Galileo ranging signals, in particular E5 AltBOC and E1 CBOC. This approach reduces the cost of the end-user solution, helping the rapid penetration of Galileo technology outside Europe

Multi-GNSS Receiver for Aerospace Navigation and Positioning Applications

“…Based on the results presented above and on the Galileo E1 signal characteristics (CBOC(6,1,1/11) modulation), it was expected that Galileo performances, in terms of code measurements noise, would outperform the ones for GPS L1 C/A by a factor of at least 3, as confirmed in other studies as the ENCORE project (Silva, P, et al, 2011), where measurement noise as low as 13cm has been reported. …”
