Proceedings of the 34th International Technical Meeting of the Satellite Division of The Institute of Navigation (ION GNSS+ 2021).
Delivering high-accuracy GNSS using a low-grade receiver is seen as a holy grail to many positioning and navigation researchers and engineers. Proposed in this paper is a methodology that overcomes many challenges posed by the noisy measurements of a

GNSS is widely known to be vulnerable to an evolving range of threats (natural and man-made, unintentional and deliberate). This drives the demand for an alternative system to protect those critical applications that depend on GNSS from a safety, sec

Proceedings of the 33rd International Technical Meeting of the Satellite Division of The Institute of Navigation (ION GNSS+ 2020).
In this paper, a sub-meter real-time positioning service for smartphones is presented. Known as FLAMINGO, the service has been in operation since early 2020. Relying only on GNSS currently, FLAMINGO can deliver 50 cm or better accuracies to consumer

2019 European Navigation Conference (ENC).
In recent months, smartphones and IoT devices have become the leading products of mass-market GNSS. However, they are still limited in their positioning capability and, even with the release of Android raw measurements in late 2016, the use of PPP an
