Special projects
Research and Publications on “Precise Point Positioning, Network
RTK, Low-Cost GNSS, Multi-Frequency Multi-Constellation GNSS”
Outreach of GNSS applications to other organisations
E.g., ICG, IAG, IHO, UN-GGIM
Involvement with regional GNSS training schools (e.g. UNOOSA,
CSIS, AIT/GIC, University of Tokyo)
Other more industry driven groups (e.g. Precision Agriculture,
Environment, Space, ITS etc)
Especially where they are related to some of the UN SDGs,
which would leverage UN-GGIM and UN-GGRF activities
Resilience in PNT (considering interference, spoofing, jamming,
ionosphere).
Very technical topic that could benefit from simplification so
that a larger section of the GNSS User community could better
appreciate it.
What we are working on -
A number of papers relating to GNSS will be submitted to
relevant conferences and technical journals.
What's New
The GNSS working group continues to support multi-constellation GNSS
activities through in the UN International Committee on GNSS (UN ICG) with
collaboration from the International GNSS Services (IGS), International
Association of Geodesy (IAG) and Multi-GNSS Asia (MGA).
Significant progress has been made in 2019 towards addressing
“Interoperability of GNSS Precise Point Positioning (PPP) Services” by
GNSS/RNSS and SBAS System Providers. WG 5.4 convened two specialized
workshops on GNSS PPP services at the Applications of Global Navigation
Satellite Systems Workshop, Suva, Fiji, 24-28 June 2019. More specifically
these sessions provided presentations to increased awareness of the
system-provided PPP services, the user benefits, and opportunities to
support point navigation and timing applications in developing countries.
It also encouraged standardization and interoperability of the system
provided PPP services. A joint meeting took place at the 14th Meeting of
the International Committee on Global Navigation Satellite Systems
(ICG-14) in Bangalore, India, 9-13 December 2019, which highlighted the
importance to harmonize key aspects of System Provided PPP services. This
subsequently led to a recommendation to establish a Task Force within ICG
to address key aspects of “Interoperability of GNSS Precise Point
Positioning (PPP) Services”. The PPP Task Force will be chaired by
Australia (Australian SBAS), Japan (QZSS) and the European Union
(Galileo). FIG WG 5.4 is a member of the Task Force and will continue to
monitor, contribute and report on the Task Force’s progress and work.

In terms of Outreach and capacity building activities beyond those
mentioned above for ICG et al, FIG WG 5.4 is actively involved in two
working groups within the UN GGIM’s Subcommittee on Geodesy (SCoG). At
present, these two groups - Outreach & Communication (OC), and Education,
Training and Capacity Building (ETCB) - are focussed on their respective
activities in raising awareness about, and adoption of, the Global
Geodetic Reference Frame (GGRF) in support of current and future
mass-market satellite-based positioning needs and applications as well as
the UN SDGs. In particular, the WG ETCB will be presenting a paper at FIG
WW 2020 on the results of a global Questionnaire around the perceived
geodetic Reference Frame competency levels around the world, and
subsequently the global geodetic community’s needs around ETCB. Also, all
working groups on the SCoG are involved with the definition of how the
proposed UN GGIM Global Geodetic Centre of Excellence (GGCE) could look
like in terms of governance, mandate and objectives. can be found

Additionally, FIG WG 5.4 was approached directly by ISO TC20/SC14/WG1
to assist with reviewing WD24246 - the development of a new standard for
‘GNSS positioning augmentation centers’. This review process will continue
into 2020, with an expected publication near the end of 2020. With this
new standard, it is expected that the dissemination of GNSS augmentation
information from solution providers will be open, unambiguous and
accessible to the growing user community.
In summary, FIG WG 5.4 is actively involved with those groups
responsible for helping to define the future of GNSS positioning into the
next decade, and beyond.
