Paper doi abstract bibtex A Differential Vector Delay/Frequency Lock Loop (DVDFLL) is proposed to combine the benefits of DGPS position accuracy and vector tracking robustness. The DVDFLL tracks a rover’s received satellite signals by coupling the relative solution between the rover and a base station to the base receiver’s scalar tracking loops. The DVDFLL algorithm is compared to the VDFLL and a DGPS aided VDFLL (DPS-VDFLL). Simulation and experimental results with the GPS L1 C/A civilian signal show that the DVDFLL can outperform the VDFLL in code tracking and maintain the same robustness as the VDFLL in carrier tracking. The experimental results also show the DVDFLL can maintain DGPS positioning accuracy. When the baseline between the base and rover exceeds 10 km, the DVDFLL begins to have poor carrier tracking performance.
