There has been significant work on vector tracking loops for the GPS L1 C/A signal. The
GLONASS L1 signal is very similar in structure to GPS L1 C/A, and the same vector …

As the world continues towards autonomy, the need for continuous, precise, and robust
navigation is becoming increasingly important. A new wave of modernized Global …

This paper first briefly introduces the advantages of vector tracking loops (or vector lock
loops-VLL) over traditional scalar tracking loops (or scalar lock loops-SLL) in a GNSS …

It is well-known that vector delay and frequency locked loops (VDFLLs) have several
advantages over traditional scalar tracking loops in GNSS receivers, especially in mobile …

The GNSS signal received by a GNSS receiver consists of many signals transmitted from all
visible satellites at single or multiple carrier frequencies. These signals, which are from …

This paper presents the implementation and testing results of a Vector tracking loop (VTL) in
the software-based GPS receiver. The VTL is developed based on the extended Kalman …

In this paper, a variant of the Vector Delay/Frequency Lock Loop (VDFLL) algorithm is
introduced for the GPS L1 civilian signal. The VDFLL algorithm uses a single Extended …

The GPS L5 signal, part of the effort to modernize GPS, was designed to increase
performance for civilian users. In order to fully exploit the structural innovations brought by …

In urban environments, standalone GNSS receivers can be strongly affected to the point of
not being able to provide a position accuracy suitable for use in vehicular applications. In …
