Citação: SOUSA, Fernando Manuel Gomes de; NUNES, Fernando D. – Performance analysis of a VDFLL GNSS receiver architecture under ionospheric scintillation and multipath conditions. In IEEE PLANS, Position Location and Navigation Symposium. New York : IEEE - Institute of Electrical and Electronics Engineers Inc., 2014. ISBN: 978-147993320-4. Art. nr. 6851421, p. 602-611.
Resumo: We analyze the advantages and drawbacks of a vector delay/frequency-locked loop (VDFLL) architecture regarding the conventional scalar and the vector delay-locked loop (VDLL) architectures for GNSS receivers in harsh scenarios that include ionospheric scintillation, multipath, and high dynamics motion. The VDFLL is constituted by a bank of code and frequency discriminators feeding a central extended Kaiman filter (EKF) that estimates the receiver's position, velocity, and clock bias. Both code and frequency loops are closed vectorially through the EKF. The VDLL closes the code loop vectorially and the phase loops through individual PLLs while the scalar receiver closes both loops by means of individual independent PLLs and DLLs.
