Home' Position : Position Apl May 2015 Contents • Airservices Australia has also made a
major capital investment in the nation-
wide Automatic Dependent Surveillance
-- Broadcast (ADS-B) surveillance net-
work, for which GNSS is a key enabler.
• The Civil Aviation and Safety Authority
(CASA) has put in place a number
of GNSS-based surveillance and
navigation mandates that come into
effect progressively by February 2017.
• In rail transport, GNSS is key to
dealing with Australia's aging system
of signalling and switching systems
through projects such as the Advanced
Train Management System.
• The Australian Maritime Safety Author-
ity (AMSA) is heavily reliant on GNSS
to provide services for navigation,
vessel tracking and timing systems, oil
spill response and search and rescue.
A major focus of government activity
is Geoscience Australia's leadership of
the NPI. Development of the NPI reflects
Australia's growing dependence on precise
positioning to underpin productivity and
safety improvements across the economy.
Key examples include the need for greater
efficiency in Australia's transportation,
geospatial data management and industri-
al automation systems (e.g. precision agri-
culture and automated mining). Servicing
these and other applications with high
accuracy and high integrity positioning
and timing are key drivers for the NPI.
Key components of the NPI include:
• The Australian Regional GNSS
Network managed by Geoscience
Australia, which was recently extended
to over 130 high-quality CORS under
the AuScope initiative.
• Developing a GNSS Analysis Centre
as a sovereign capability to augment
GNSS constellations and produce sig-
nificant enhancements to positioning
accuracies and system integrity.
• Investigating mechanisms for satellite
delivery of Multi-GNSS data products
for augmenting GNSS position (particu-
larly in remote areas of Australia) and
reporting integrity information, such as
system health and performance.
• Actively engaging all GNSS and RNSS
system providers on issues like hosting
of monitoring stations and cooperation
on augmentation services.
• Strengthening engagement with all
key user groups and service providers
across multiple disciplines to facilitate
interoperability and standards adoption.
GA has also been working on the
governance arrangements needed to
support these components, and has now
established the NPI Advisory Board to
provide strategic guidance and advice on
NPI planning. The NPI Advisory Board
met for the first time in Canberra in
The Advisory Board is chaired by
Geoscience Australia through Gary
Johnston (Chair), John Dawson, and
Grant Hausler (Secretariat).
Broader membership of the board
is drawn from individual experts
representing key sector groups from
Australia and New Zealand: Stuart
Ballingall -- Austroads; Graeme Blick
- Land Information New Zealand; Dr
Suelynn Choy - RMIT University; Paul
Harcombe - Land & Property Information
NSW and the Intergovernmental
Committee on Surveying & Mapping;
Matt Higgins - Department of Natural
Resources & Mines (QLD) and IGNSS
president; Nick Lemon - Australian
Maritime & Safety Authority; Rod
MacLeod -- NovAtel; Ian Mallett - Civil
Aviation Safety Authority; Tim Neale
- Precision Agriculture; and Martin Nix -
The strategies and work plan of the
NPI-AB are still being developed but the
Australian Strategic Plan for GNSS that
was developed by the Australian Spatial
Consortium is seen as a useful pointer to
the types of issues that will need to be ad-
dressed by the board. Such issues include:
• Ensuring there is leadership for the
Australian GNSS community.
• Adopting a whole-of-nation approach to
a sustainable, Multi-GNSS-enabled NPI.
• Mitigating vulnerabilities in existing
and future GNSS infrastructure.
• Capitalising on Australia's unique
IGNSS 2015 will have a dedicated
stream of sessions devoted to the NPI that
will focus on applications with presenta-
tions from the key sectors outlined above.
The NPI sessions will also focus on issues
associated with the operation of the
infrastructure itself. That will involve key
players from the private and public sector
who operate CORS stations and associated
precise positioning services. It will cover
issues such as the importance of a uniform
reference frame across all networks, the
importance of quality assessment and cer-
tification, and the possibilities for coopera-
tion between operators through sharing of
data and the associated business models.
These NPI presentation sessions will be
complemented by panel discussions that
will allow delegates to give direct feedback
to members of the NPI-AB and to CORS
operators on issues that they see as impor-
tant for the future of GNSS in Australia.
The technical sessions and panel
discussions at IGNSS 2015, will be
complemented by an extensive technical
exhibition, featuring local and global
suppliers offering a broad range of state-
of-the-art PNT hardware, software and
Matt Higgins is president of the
IGNSS Society, a member of the USA's
Space-Based Position Navigation and
Timing Advisory Board and of Australia's
National Positioning Infrastructure
Advisory Board. In his day job, Matt is
manager of Geodesy and Positioning in
the Queensland Department of Natural
Resources and Mines.
Grant Hausler coordinates planning
and development of the National
Positioning Infrastructure (NPI) project
at Geoscience Australia. He is a member
of the NPI Advisory Board, the Australian
Government Positioning, Navigation and
Timing (PNT) Working Group and the
Space Community of Interest.
IGNSS 2015 will be held from 14-16
July 2015 at the Outrigger Hotel, Surfers
