Global Geodetic Reference Frame
 The GGRF underpins the
global coordinate system
 Allows us to know where
we and things on the
Earth are

Global Geodetic Reference Frame
 The GGRF underpins
most geospatial data
 It’s inherent in GPS
coordinates

 All countries can and (if
possible) should
contribute to the GGRF

 Today’s GGRF is an
enormous improvement
over geodetic
infrastructure developed
before satellite geodesy

 The GGRF is a sparse
global infrastructure of
core observatories

 The GGRF is needed for
high accuracy satellite
positioning
 GNSS networks provide
access to the GGRF

 The GGRF is needed to
measure crustal velocities
and consequently inform
decision makers about
seismic hazards
 The GGRF is needed to
measure global sea-level
change

Sea Level Rise
 Much of the world’s population live in the coastal zone
 Rising sea levels and storm surges will have significant
impacts on many of our coastal towns and cities
 Understanding the risks to infrastructure and private
property is important
 Geodetic Infrastructure underpins our understanding of sea
level change and its impacts

 GGRF is important for
 Sea-wall construction
 Managing development in flood prone areas
 Improving building codes and practices
 Improving drainage and flood mitigation construction

 Significant economic
benefits arise from the use
of GGRF and satellite
positioning
 This presentation will
provide some benefit
examples from Australia
 These examples are
transferable to all other
countries, developed or
developing

Economic Benefits of Positioning: Agriculture
 Australian agriculture sector contributes 2-3% of GDP
 Applications: precision agriculture
 Impacts
 Upto 25% reduction in fertiliser
 Upto 50% reduction in diesel fuel usage

Economic Benefits of Positioning: Mining
 Applications
 mine surveying, autonomous mining, machine
guidance
 Depending level of automation
 productivity gains can include labour force reduction
from between 5% and 50%,
 productivity gains ranging between 1% and 15%

Economic Benefits of Positioning: Construction
 Applications: surveying, machine guidance and asset
management
 Require an accuracy of around 2 cm
 Savings 10% to 20% achieved with machine guidance

Economic Benefits of Positioning
Precise satellite positioning technology could potentially add up
to 2.1% to Australia’s GDP by 2030 through productivity gains
in mining, construction and agriculture alone

Key Messages
 Satellite positioning is vitally important to the economy,
environment and society
 The ability to position both information and objects
accurately will be an increasingly important driver of
prosperity
 The GGRF underpins global change science and
supports improved disaster risk reduction
 With modest infrastructure investment all countries
can obtain the benefits of and contribute to the GGRF
