The annual ION GNSS+ meeting was held in Miami, Florida, from September 16 - 20, 2019. I was surprised, and initially disappointed, that there was no session dedicated to precise point positioning (PPP) this year. However, it quickly became clear that PPP-related research is still going strong: it has simply evolved to focus on low-cost GNSS devices, smartphones and integrity.
The IGS Workshop 2018 was held from 29 October to 2 November in Wuhan, China. One of the focus of the workshop was to align efforts towards incorporating multi-GNSS products in the standard line of IGS products. As a bonus, we might even see products enabling PPP with ambiguity resolution (PPP-AR) in a not-so-distant future!
From 24-28 September was the ION GNSS+ meeting held in Miami, Florida. Evolutions in the conference name (now including the “+”) are well reflected in the content. Research on precise point positioning (PPP) is now driven by the automotive industry which calls for less stringent accuracy needs but higher integrity. This blog post summarizes what I consider to be the key points of the conference from a PPP perspective, with an emphasis on low-cost devices and integrity.
The 2017 edition of the IGS Workshop was held in Paris from 3-7 July. I had the pleasure to attend this meeting for the first time and was quite pleased with the quality of the talks and the networking opportunities. Below is a summary of what I consider were important topics: these notes are based on my own understanding of the presentations and I encourage you to look for the original presentations for all the details once they are made available on the workshop website.
Processing of GNSS data requires proper handling of measurement biases originating from delays within the satellites and receivers. This is especially true for PPP with ambiguity resolution (PPP-AR) which relies heavily on code (pseudorange) observations. The objectives of the IGS Workshop on GNSS Biases 2015, held on November 5-6 in Bern, Switzerland, were therefore to better characterize GNSS biases, describe ways of handling such biases and define standard formats to exchange bias information
