The objective of the project is the development of a prototype of a future space qualified multichannel RF module for an on-board GNSS receiver, with its validation environment (digital subsystem, related software procedures, analysis and validation methods): manufacturing and testing of several test boards as well as the design and layout of an elegant breadboard for the RF subsystem; realization of a digital subsystem integrating signal filtering and conditioning functional blocks for pre-processing of the signals prior to sending it to a host computer for analysis; computer application for initializing the RF module, monitor data transfer, log and process data in real time or after their storage.
