Cross-platform evaluation for Software Defined Radio GNSS receiver
Nowadays, Global Navigation Satellite Systems (GNSS) and complementary positioning technologies are expanding, offering new resources to the localization process. Software Defined Radio (SDR) is emerging as an alternative to developing flexible and multi-technology solutions in a dynamic environment. This work describes the main operational signals in GNSS systems that can be used in a multi-constellation, multi-frequency receiver. Also, it proposes the reception of GNSS signals using a modular architecture based on SDR. The SDR GNSS receiver is confronted with two platforms operating as Front-Ends: ADALM-PLUTO and Ettus USRP X310 - UBX160. The results, corresponding to the capture of GPS signals in the L1 band, show the impact of the platform’s performances in the satellite acquisition signal process.
