Abstract:	This paper presents a high-level view of the Combined Positioning-Reflectometry Galileo Code Receiver for Forest Management (COREGAL) System architecture, focusing on the development of a GNSS-P+R (Positioning and Reflectometry) receiver. The COREGAL GNSS-P+R receiver will be the main sensor platform for positioning and biomass estimation. Biomass estimation uses GNSS reflectometry (GNSS-R) signals propagated through tree canopies. The goal of this work was to develop a GNSS receiver capable of simultaneous high-accuracy positioning and raw reflected signal acquisition. The first prototype of the receiver is currently under testing. This paper also presents the results for the first COREGAL field campaign. The purpose of this test campaign was to receive GNSS signals reflected over vegetation, generating GNSS-R raw data using Galileo E5 signals.
