NAVISP-EL1-126-APPROXIMATE COMPUTING FOR LOW-POWER GNSS SIGNAL PROCESSING - EXPRO+

General DescriptionThis activity explores the application of Approximate Computing (AxC) techniques to GNSS signal processing for reducing power consumption while maintaining acceptable accuracy. It focuses on implementing AxC in acquisition, tracking, and PVT stages of GNSS receivers. The study will identify suitable AxC methods, develop a prototype receiver supporting both exact and approximate modes, and evaluate performance in terms of power efficiency, accuracy, and correlation degradation. Test campaigns will use live and replayed GNSS data from various environments to validate the concept. For more info, visit https://navisp.esa.int/opportunity
