LightSquared Urged to Use Different SpectrumPreliminary test results released in June confirm that the new broadband network proposed by LightSquared will cause interference with GPS signals if it is allowed to launch in the planned spectrum.
“The test data discussed today makes clear that there is substantial interference to GPS if LightSquared turns on high-powered terrestrial facilities in the spectrum next door to GPS,” said James Kirkland, Trimble vice president and general counsel and founding member of the Coalition to Save Our GPS, speaking at a June event sponsored by the National Space-Based PNT Advisory Board. “The data confirm what the industry told the FCC before it granted the waiver and also confirms that there is no viable technical fix.”
Kirkland added that broadband and GPS should not be an either/or situation. “The United States can, and should have both,” he said. “LightSquared says it has other spectrum, and it should use it.”
A waiver granted to LightSquared in January by the FCC’s International Bureau allows the dramatic expansion of terrestrial use of the mobile satellite spectrum (MSS) immediately neighboring that of the GPS using extremely high-powered ground-based transmissions. Tests have shown that these transmissions will cause interference to hundreds of millions of GPS receivers across the United States.
At the June event, Kirkland and government representatives discussed testing conducted to measure interference to GPS receivers used in aviation and other critical government applications. In at least one test, LightSquared failed to deliver test equipment that matches its proposed operations, thus causing optimistic results–and even those optimistic results showed interference.
LightSquared was due to file an FCC-mandated Working Group Report on June 15. However, the company requested--and was granted--a two week extension. “After pushing the FCC to order an accelerated review of the interference issues raised by its proposed service, a process that has consumed massive governmental and private resources, LightSquared has now unilaterally sought to delay the process for two weeks,” Kirkland said. “It is disappointing that LightSquared has misused its control over the process to delay this filing. It’s time for LightSquared and the FCC to stop squandering resources and move on to spectrum that does not impact GPS.”

ILSC 2011 Highlights Technology ConvergenceOptech Inc.’s second Innovative Lidar Solutions Conference (ILSC 2011), held May 31 to June 3 at the Hilton Garden Inn Toronto, drew 200 attendees from 23 countries. According to Brent Gelhar, vice president of sales and strategy for Optech, the goal was to bring continuing awareness of the convergence of imaging and 3D measurement technologies. “The speakers, especially the keynotes, enthusiastically emphasized this convergence,” Gelhar said.
A keynote by Paul DiGiacobbe, PE, national data acquisition manager for HNTB, focused on the growing trend toward mobile LiDAR for infrastructure projects due to the time and cost savings it provides. DiGiacobbe noted that surveyors play a key role in mobile LiDAR data acquisition.
A session on market directions highlighted several new technologies that promise to have an impact on workflows in the future. For example, the TABI-1800 Thermal Airborne Broadband Imager from Itres captures swaths of 1800 pixels, allowing users to map large areas in a small amount of time at a substantial line cost savings. The VG4D SmartLiDAR software from Virtual Geomatics addresses key issues in LiDAR data collection and processing, including quality control and cloud adjustment, working with giant datasets, automatic cloud classification, and automatic and manual linearization. The LANDINS, AIRINS and QUADRANS inertial measurement units (IMUs) from iXSea integrate high-performance fiber-optic gyroscopes (FOG) to provide high accuracy and rapid alignment for faster, higher-quality data acquisition in both mobile mapping and aerial surveying applications. And the POSPac MMS software from Applanix integrates GNSS and IMU technology to provide direct georeferencing of mobile mapping sensors for improved accuracy and increased productivity.
Optech launched several new technologies at the conference, including the Aquarius bathymetry extension to Optech’s ALTM Gemini line and a new higher-performance waveform digitizer (see New & Notable on page 60 for more details) as well as data processing software enhancements for the Lynx Mobile Mapper and the ILRIS Terrestrial Laser Scanner family.
“All in all, the conference goals were met and exceeded, especially in light of the excellent turnout,” Gelhar said. Optech’s website iswww.optech.ca.
Hexagon 2011 Delivers Actionable InformationMore than 2,500 attendees from 65 countries gathered in Orlando, Fla., June 6-9 for the inaugural Hexagon 2011 conference. With the theme “Building a Smarter World,” the conference combined the latest technologies and user communities from Leica Geosystems and Z/I Imaging as well as Intergraph and Hexagon Metrology.
In the opening keynote address, Hexagon AB President and CEO Ola Rollén discussed the numerous ways in which users are applying technology to make processes and infrastructures better, safer and smarter. He noted that change drives progress and can be harnessed to our advantage. Hexagon and all of its divisions are dedicated to delivering actionable information through design, measurement and visualization technologies, he said--a commitment that is captured in Hexagon’s new mission statement. By empowering customers to create, manage and share information, Hexagon aims to help them increase productivity, improve quality, and make better and faster operational decisions.
One example of this empowerment was the launch of Leica Geosystem’s new ScanStation C5 laser scanner, a compact, scalable tool with a starting price of under $50,000. The new instrument created a substantial amount of buzz among attendees in the Geosystems track since it offers another low-cost option for geospatial professionals who are trying to expand into laser scanning--a market that has previously been considered too expensive for many firms. “With the new C5, we can help more surveyors get into this market and we can custom-build their scanner for their markets,” said Michael Harvey, HDS product marketing manager for Leica Geosystems. “We’re really excited about that.” (See New & Notable on page 60 for more details on the ScanStation C5.)
Also highlighted was Leica’s new ALS70 and its family of systems for airborne LiDAR use, which provides high-density, high-accuracy data in a short amount of time. “The qualities that increase the value of raw data are the speed with which it is gathered and the latency with which it is processed,” said Ron Roth, product manager for airborne LiDAR. “Both of these values have been significantly enhanced throughout the 13-year history of LiDAR product development at the Geospatial Solutions Division. It continues to be an exciting product line to be involved with.”
The Geosystems track at the conference included a keynote address by Jürgen Dold, president of Hexagon Geosystems, and Ken Mooyman, president of Hexagon Geosystems NAFTA, who highlighted how measurement technologies are being used in innovative ways to advance Earth’s infrastructure. Examples included the precise layout of high-speed railways to ease urban traffic congestion; the use of integrated geospatial sensors to allow the precise construction of tall skyscrapers that help resolve urban space pressures; and increasingly sophisticated scan-to-BIM processes that make it easier for communities to rebuild after a natural disaster.
Although the event was held less than eight months after the Leica Geosystems HDS Worldwide User Conference, attendance from the survey audience was still high. A number of attendees in the Geosystems track said they appreciated the opportunity to network with the larger group from Intergraph since many of those participants are consumers of survey data. Information gleaned from the conference provided food for thought on capturing new business, increasing productivity and adding value to a data-driven world.
Preparations are already underway for next year’s conference, which will be held June 4-7 in Las Vegas. For more information, visitwww.hexagonconference.comorwww.leica-geosystems.us.
