GPS Offers Enormous Valueto Developing Nations • Obviates need to develop local infrastructure for positioning, navigation, and timing • Example: Availability of GPS time eliminates need to build terrestrial time distribution networks • Supports a wide range of sustainable development activities including: • Surveying, mapping, GIS • Construction, mining • Agriculture • Timing for telecom, banking, power grid management • Disaster management • Environmental stewardship
Surveying, Mapping, GIS • Surveying is essential to any new development • Electrification • Telecom tower placement • Pipeline installation • Dam construction • Port dredging • GPS enables 2-5 cm real-time positioning accuracy • Mm-level accuracy possible with post-mission data processing • 100%-300% savings in time, cost, labor • Stakeless, paperless surveys
Construction, Mining • Faster site preparation • Enhanced management of assets, equipment • More efficient asset utilization • Less idling of workers, machinery • Precise machine control • Up to 70% increased job site productivity • Saves time, fuel, and emissions • Reduces maintenance • Prevents accidents • Automated, wireless job tasking • Smaller, more empowered workforce – no foreman • Real-time progress tracked remotely
Agriculture • Improved management of land, machinery, personnel, time • Optimized placement of crop rows, seeds • Enhanced monitoring of crop yields, soil quality, problems • Automated, 24-hour operations using lighter equipment, less fuel, less labor • Plant-specific applications of water, fertilizer, pesticides, herbicides • Up to 80% increase in efficiency • Greater crop yields, profit margins • Environmental benefits • Reduced chemical use • Precise leveling of fields reduces runoff • Strip tillage/no tillage releases less CO2 • Reduced CO2 emissions from lighter, more efficient machinery
Timing • GPS offers an inexpensive alternative to high-maintenance timing equipment, networks • Synchronization, management of communication networks • Phones, pagers, wireless systems • LANs, WANs, Internet, satellites • Cell phone tower handoffs • Digital TV • Financial transactions • Stock exchanges • ATMs • E-commerce • Power grid management • Load balancing • Fault detection, location
Disaster Management • Assists in disaster planning efforts such as flood plain mapping • Helps relief workers navigate disaster areas devoid of landmarks • Facilitates containment and management of wildfires • Enables disaster warning systems • GPS-equipped buoys for tsunami warnings • GPS ground networks monitor crustal motion, earthquakes
Environmental Stewardship • Climate monitoring • Sea level rise measurements • Ice sheet change observations • Atmospheric moisture profiles • Reduced greenhouse gas emissions • Efficient routing of aircraft, trucks, and other vehicles • Reduction of vehicle fleet idle times • Oil and chemical spill cleanup • Positioning, modeling of spills to guide remediation efforts • Commercial fishing • Enforcement of fishery boundaries • Forestry • Monitoring of illegal deforestation
New Applications Appear Every Day • Mobile applications • Location based services • Localized GIS datasets • Personal, pet safety • GPS radio occultation • Road use taxation
Emerging Market Opportunities • Use of new civil GPS capabilities • Combined use of GPS and international systems • Integration of GPS with other positioning, navigation, and timing (PNT) capabilities
New Civil GPS Capabilities • Ongoing modernization program is adding three new civil GPS signals • L2C, L5, L1C -- in addition to existing L1 C/A • Technical documentation available online, free • Availability of new GPS capabilities will drive user equipment sales, upgrades • New signal designs and signal combinations will spur new applications, markets
New Civil GPS Capabilities:Second Civil Signal (L2C) • Designed to meet commercial needs • Higher accuracy via ionospheric correction • Eliminates need for “semi-codeless” GPS technology, which is being phased out by 2020 • Required upgrades will drive equipment sales • Expected to generate over $5 billion in user productivity benefits • Currently available on 7 operational satellites • On 24 satellites by 2016 Benefits existing professional receivers Increases accuracyfor consumers Supports miniaturization, possible indoor use
New Civil GPS Capabilities:Third Civil Signal (L5) • Designed to meet demanding requirements for transport safety • Uses highly protected Aeronautical Radionavigation Service (ARNS) band • Will lead to new sales of dual-frequency equipment for aircraft, other vehicles • Commercial innovation expected from availability of triple-frequency GPS • Sub-meter, standalone positioning • Opportunity for international interoperability • Demo signal activated in April 2009 • GPS IIF satellites with L5 begin launching in June 2010 • 24 satellites by 2018
New Civil GPS Capabilities:Fourth Civil Signal (L1C) • Designed with international partners for interoperability • Modernized civil signal at L1 frequency • More robust navigation across a broad range of user applications • Improved performance in challenged tracking environments • Original signal retained for backward compatibility • Launches with GPS III in 2014 • On 24 satellites by ~2021 Under trees Inside cities
Combined Use of GPS andInternational Systems • Many nations are developing GPS augmentations and/or independent satellite navigation systems • Europe (Galileo, EGNOS), Russia (Glonass, SDCM), China (Compass), Japan (QZSS, MSAS), India (IRNSS, GAGAN) • USG is consulting with all of them to promote GPS compatibility and interoperability • Ideally, this will allow seamless, combined use of multiple systems for improved performance • Future users will want to use all available systems, driving new equipment sales and applications -- significant commercial opportunities, BUT: • Must maintain level playing field in global marketplace • Equal access to signals, information, and user markets • No mandated use of one system over another
Integration of GPS withOther PNT Capabilities • Growing dependence on GPS for critical applications creates potential vulnerabilities • GPS signal is susceptible to interference • Integration of GPS technology with complementary or backup capabilities has begun • Cell-based positioning, WiFi hotspot location, digital compasses, accelerometers, inertial sensors, etc. • Future technologies may include eLoran, chip-scale atomic clocks • As users recognize limitations of GPS, demand for integrated PNT capabilities may increase – creating market opportunities
Summary • U.S. policy promotes global use of GPS technology • GPS offers enormous value to developing nations • Supports a wide range of sustainable development activities • New commercial markets will open as: • GPS modernization occurs • International systems emerge • Users seek more robust PNT services
