Encourage industry “champions” by creating opportunities for government agencies & private Encourage “industry champions”... sector organisations to exercise leadership & responsibility.5. Communicate with all sectors of the GNSS community on implementation issues & progress. Communicate with all stakeholders...6. Advocate for the need to upgrade the fundamental reference station network to support multi- GNSS tracking, to invest in the development of a new geodetic datum, & to coordinate the Upgrade of CORS to multi-GNSS... new activities of federal & state government agencies & the private sector. geodetic datum, etc. Canberra, 20-22 November 2012
    • What does this mean?• “Sell” GNSS harder...to govt & industry• Educate policy-makers on economic (& other) benefits of GNSS... what would we do without it?• Link GNSS to “digital future”... NBN, ICT infrastructure, etc.• Coordinate federal agencies with GNSS agendas... GA, CASA, SPU, ACMA, OSP...• Increase coordination across government & private sectors & academia... especially re augmentation, stds & specs, QC, etc.• Move away from GPS-only to multi-GNSS... build-in upgrade paths into GNSS investments by users & service providers• New geodetic/mapping datum definition based on ITRF Canberra, 20-22 November 2012

    • Recommendation 2: Adopt a whole-of-nation approach to a sustainable, multi-GNSS-enabled NPI Identify NPI activities...1. Identify existing NPI-related activities of government & private sector CORS providers.2. Identify and mitigate investment risks by analysing & resolving duplication, fragmentation, Coordinated roll-out of GNSS component of NPI... consistency, timeliness & funding issues, with a view to ensuring a coordinated roll-out of the GNSS component of the NPI. Build GNSS component of NPI on hierarchical3. Coordinate the deployment of the GNSS component of the NPI based on capability to meet the above principles efficiently & effectively, to ensure that the NPI is built on hierarchical principles, & principles...technical & commercial operating Consistent link to geodetic datum... is strongly linked to the fundamental global GNSS reference station network and geodetic datum.4. Establish & enforce consistent technical & commercial operating principles so that high accuracy & principles... governance, funding & business Appropriate high integrity users are assured of the quality of enhanced GNSS by all service providers.5. Establish appropriate governance, funding & business models to operate the NPI & deliver NPI- models... international collaboration... Coordinate related products & services.6. Coordinate international collaboration in multi-GNSS regional & global initiatives, campaigns & campaigns, tests, etc. tests. Canberra, 20-22 November 2012
    • What does this mean?• Develop an NPI Plan...for federal govt & other agencies, e.g. to minimise duplication of CORS, etc.• NPI to be promoted as “critical infrastructure”...and funded• Encourage development of value-added services...high accuracy and high integrity markets• CORS networks & geodetic datum extend beyond state & national boundaries...coordination, international engagement• Manage CORS & DGNSS services growth...not only hardware components• Transitioning from GPS-only to multi-GNSS often implies “rewriting the textbook”...and do it quickly Canberra, 20-22 November 2012

    • Recommendation 3: Mitigate vulnerabilities in existing and future GNSS infrastructure1. Ensure the NPI is formally identified as Critical Infrastructure. NPI as “critical infrastructure”...2. Form a Community-of-Interest as part of the Trusted Information Sharing Network (TISN) for Critical Infrastructure Resilience. C-o-I within TISN...3. Investigate the role of an SBAS within an NPI, what form it should take, what its functionality Investigate SBAS as part of future NPI... must be, & the partnership arrangements for its deployment & operation.4.

Mitigate GNSS dependency risks by: Mitigate GNSS dependency... alternative PNTs, • Ensuring broad adoption of multi-GNSS, thereby eliminating single system dependence. • Promoting the appropriate use of non-GNSS back-up & augmentation technologies. address vulnerabilities, etc... • Encouraging the development & deployment of alternative PNT systems where GNSS cannot operate effectively. • Address issues of vulnerability. Canberra, 20-22 November 2012
    • What does this mean?• GNSS-enabled NPI is critical infrastructure... needs to be maintained, and protected• Intentional and unintentional RFI is a big concern... one of GNSS’s greatest vulnerabilities• Need to manage GNSS vulnerabilities... mapping impact of GNSS loss, identifying back-up technologies, what’s our “Plan B”? etc.• Some mitigation of risk going from GPS-only to multi-GNSS• SBAS for some users... but a big step, that would require a big investment• No alternative PNT technology with same performance characteristics as GNSS... but terrestrial systems possible• Some environments will never be suitable for GNSS... e.g. indoor positioning Canberra, 20-22 November 2012
    • Increasing sense of GNSS Vulnerability: intentional (and unintentional) jammingIn late 2009 satellite positioning receiversfor a new navigation aid at Newark airportwere suffering brief daily breaks inreception. It took two months forinvestigators to track down the problem:a driver who passed by on the NewJersey Turnpike each day had a cheapGPS jammer in his truck because he didnot like his employer tracking his everymove.TheEconomist, March 10, 2011(www.economist.com/node/18304246)~ Illegal in Australiabut still needs to be watched. Canberra, 20-22 November 2012
    • Beyond GNSS... Locata: Australian-designed, terrestrial, GNSS-like PNT technology able to augment GNSS (e.g. open-cut mines) or replace GNSS (e.g. vulnerable apps) or be used where GNSS never could operate (e.g. indoors), within coverage area of local transmitter network.

    • Recommendation 4: Capitalise on Australia’s unique geopolitical advantage Promote Australia’s advantages as a “partner”...1. Promote the unique benefits and opportunities that stem from Australia’s geopolitical status as a politically stable, middle-power, with advanced infrastructure, an educated workforce, an active industry sector & a world class R&D capability: • Encourage GNSS system providers to locate & operate ground monitor stations in Australia. • Encourage GNSS receiver manufacturers & application developers to engage with Australian companies & research organisations to develop, test, validate & demonstrate innovative Attract overseas investment in Australian GNSS products & services in Australia. businesses, etc...2. Attract overseas investment in Australian-based GNSS businesses & research organisations. Assist neighbouring countries...3. Assist neighbouring countries with GNSS infrastructure development, technical advice, education & skills development. Address capacity needs & skill requirements...4. Determine capacity needs & skills requirements to service Australia’s growing GNSS industry. Grow the education & research sectors...5. Grow the education & research sector to service demand for skilled GNSS engineers, scientists & researchers. Canberra, 20-22 November 2012
    • What does this mean?• Use the fact Australia is located in Asia-Pacific GNSS “hot spot” to its advantage... promote experimentation, joint tests, indigenous product & service development, R&D, etc.• Australia has special PNT market needs... promote R&D into better GNSS support for agriculture, mining, transport, etc.• Invite GNSS signal providers to set up monitor stations in Australia... “security concerns” should not stifle international cooperation• Investigate GNSS/PNT training/education needs... primarily for navigation, geospatial & mapping sectors• Grow our GNSS R&D capability... primarily at universities, but also CSIRO, NICTA Canberra, 20-22 November 2012
    • Concluding Remarks• GPS has introduced revolutionary PNT capabilities.• Multi-GNSS will bring many benefits, but uptake will depend on constellation deployment, user equipment, infrastructure, procedures & services.• (Continued) international engagement and cooperation is vital.• Addressing GNSS shortcomings/vulnerabilities is essential.• “Australian Strategic Plan for GNSS” identified constraints to increased & more effective GNSS adoption by critical industries & made some recommendations.• The Professional Market has significant influence on infrastructure & GNSS developments, and is a significant consumer of GNSS products & services.
