    Wilpena Pound, shown above, is a natural amphitheater of mountains in the heart of Flinders Ranges National Park in South Australia. Wilpena Pound is 17 kilometers long and 8 kilometers wide, covering an area of 100 kilometers. The highest peak is St. Mary Peak, at 1,170 meters.

    The WorldDEM Digital Elevation Model of the Pound is based on data acquired by the German high-resolution radar satellites TerraSAR-X and TanDEM-X, which started synchronous data acquisition in December 2010 and completed coverage of the Earth’s entire landmass twice over in mid-2013. The satellites covered more complex terrain areas with a third and fourth acquisition campaign to ensure accuracy for the WorldDEM mapping database, a 3D global pole-to-pole digital elevation model distributed by Airbus Defence and Space.

    Since its commercial launch in April 2014, WorldDEM has provided high-precision elevation models to a wide variety of industries. Mining studies in equatorial regions use it to analyze dense vegetation. It’s used for infrastructure corridor design and costing. Military and civil aviation use it for low-altitude flight path and landing-area planning for helicopters and aircraft in remote and difficult to access areas.

    The database now covers large parts of North and South America, Western and Southern Africa, the Middle East, Australia, Northern Europe and Asia. The most recent additions include complete coverage of Scandinavia, Ukraine, Iran, Iraq, Angola and Saudi Arabia. In all, 80 million km² of WorldDEM data has been captured.

  • GPS III Launch Services RFP Released by Air Force

    The U.S. Air Force released a final Request for Proposal (RFP) for GPS III Launch Services on Sept. 30. Launch services include launch vehicle production, mission integration and launch operations for a GPS III mission scheduled to launch in 2018. Proposals are due back to the Air Force no later than Nov. 16 in accordance with the solicitation instructions.

    After evaluating proposals through a competitive, best-value source selection process, the Air Force will award a firm-fixed price contract that will provide the government with a total launch solution for the GPS III satellite. The Air Force’s acquisition strategy for this solicitation achieves a balance between mission success, meeting operational needs, lowering launch costs, and reintroducing competition for National Security Space missions, according to a statement by the Air Force.

    “Through this competitive solicitation for GPS III launch services, we hope to reintroduce competition in order to promote innovation and reduce cost to the taxpayer while maintaining our steadfast laser focus on mission assurance and assured access to space,” said Lt. Gen. Samuel Greaves, Space and Missile Systems Center commander and Air Force Program Executive Officer for Space.

    This will be a standalone contract for one GPS III launch, the Air Force said. This is the first of nine competitive launch services planned in the FY 2016 President’s Budget Request under the current Phase 1A procurement strategy, which covers awards with FY 2015-2017 funding. The next solicitation for launch services will be for a second GPS III mission.

    The Phase 1A procurement strategy reintroduces competition for national security space launch services. Under the previous Phase 1 strategy, United Launch Alliance (ULA) was the only certified launch provider. In 2013, ULA was awarded a sole-source contract for launch services as part of an Air Force “block buy” of 36 rocket cores that resulted in significant savings for the government through FY 2017.

    In May, Space Exploration Technologies (SpaceX) was certified for EELV launches resulting in two launch service providers that are qualified to design, produce, qualify and deliver a launch capability and provide the mission assurance support required to deliver national security space satellites to orbit.

    “With the recent certification of SpaceX, we now have multiple launch service providers that can service critical NSS missions. Reintroducing competition into EELV will ultimately save taxpayer dollars and increase assured access to space. ” said Claire Leon, director of SMC’s Launch Enterprise Directorate.

    “As part of this reintroduction of competition, we’ve been working with our industry partners to develop and finalize this RFP,” said Leon. “Their feedback has been critical to developing the criteria for this source selection and how we are innovating government processes to better match commercial processes as directed by OSD’s Better Buying Power 3.0. This is an exciting time in NSS launch acquisitions.”

    GPS III is the next generation of GPS satellites that will introduce new capabilities to meet the higher demands of both military and civilian users. GPS III is expected to provide improved anti-jamming capabilities as well as improved accuracy for precision navigation and timing. It will incorporate the common L1C signal which is compatible with the European Space Agency’s Galileo global navigation satellite system and compliment current services with the addition of new civil and military signals.

    The Air Force Space Command’s Space and Missile Systems Center, located at the Los Angeles Air Force Base, Calif., is the U.S. Air Force’s center of excellence for acquiring and developing military space systems.  Its portfolio includes the Global Positioning System, military satellite communications, defense meteorological satellites, space launch and range systems, satellite control networks, space based infrared systems and space situational awareness capabilities.

    Tallysman Introduces High-Gain, High-Rejection Timing Antennas

    Photo: Tallysman Antenna maker Tallysman announces the availability of a family of high-gain (50 dB) and high-rejection timing antennas.

    The antennas are specifically designed for timing applications in high-density cell/telecommunications tower applications where high levels of near-out-of-band interfering signals can be expected. They feature a 50-dB LNA gain to handle long cable runs often associated with installation on telecommunications towers.

    The TW3150/52 antennas cover the GPS L1 and SBAS (WAAS, EGNOS and MSAS) frequency band and employ Tallysman’s unique Accutenna technology to provide excellent cross-polarization rejection and greatly enhanced multipath rejection.

    The TW3150 antenna features a four-stage dual-filtered LNA, while the TW3152 antenna includes an additional SAW pre-filter to provide exceptional rejection of close out-of-band signals and additional protection against saturation by high-level sub-harmonic and L-Band signals. This provides better than 80-dB of signal rejection above 1610 MHz and below 1545 MHz, Tallysman said.

    The antennas have a permanent mount, IP67 and MIL-STD-801F Section 509.4 compliant housing with metal base and an extended temperature range plastic radome, and is specifically designed to withstand the most challenging environmental conditions.

    Two options for mounting are available: an L-bracket (P/N#23-0040-0) or a pipe mount (P/N#23-0065-0).

    The new antennas are REACH and ROHS compliant.

  • Denver, FAA Partner on Drone Safety

    Denver International Airport and the Federal Aviation Administration (FAA) are partnering to raise awareness about safe unmanned aircraft operations.

    The agencies teamed up on a public service announcement that will run on the video towers in the airport’s main terminal. The PSA uses the “No Drone Zone” slogan to drive home the point that flying an unmanned aircraft near a manned aircraft is illegal and dangerous. It refers viewers to the FAA’s unmanned aircraft website and to the knowbeforeyoufly.org website for further information and guidance on flying unmanned aircraft safely and responsibly.

    The PSA will air all day today following its unveiling at an unmanned aircraft safety press event that the airport organized and hosted. After that, it will air for two weeks surrounding the winter holidays — a time when many people will be getting drones as gifts.

    Denver also will post the PSA on the airport website so it will reach travelers every day of the year.

    The FAA has partnered with leading unmanned aircraft industry and hobbyist groups in the Know Before You Fly education campaign, and the campaign materials are now featured in product packaging for several types of UAS.

    Trimble’s TIMMS 2 Provides Maneuverable Indoor Mapping Solution

    Photo: TrimbleTrimble has introduced its next-generation Trimble Indoor Mobile Mapping Solution (TIMMS) that produces fast and accurate maps of difficult-to-navigate indoor spaces and translates them directly into 2D and 3D models of structured interiors.

    TIMMS 2 is a fusion of technologies for capturing spatial data of indoor and other GNSS denied areas, the company said. It provides both lidar and spherical video, enabling the creation of accurate, real-life representations of interior spaces and all of their contents. The maps are geo-located, meaning that the real world positions of each area of the building and its contents are known and can be easily placed and oriented in a wide area model.

    TIMMS 2 is smaller, lighter and more easily maneuverable than its predecessor. It can negotiate tight corners, closets and catwalks, and can be carried up and down staircases where no elevator is available for travel between building levels.

    “The new Trimble Indoor Mobile Mapping Solution has been designed with greater emphasis on ease of use. It is very easy to maneuver, lift, ship and operate,” said Louis Nastro, director of Land Products at Applanix, a Trimble Company. “Our extensive experience with a broad range of projects with the previous generation TIMMS has led to a number of enhancements in data collection, processing and workflow management — making an indoor mapping project a seamless experience for users both pre- and post-mission. Whatever the building type and shape, TIMMS 2 can deliver exceptional results, both in accuracy and ease-of-use.”

    Building on the success of the first-generation solution, TIMMS 2 also provides improved software workflow to manage the complete process from collection through post-processing to model production. Fully compatible with POSPac MMS, Applanix’ post-processing suite, TIMMS data can be presented in a variety of ways, including integration into Trimble Business Center and other infrastructure management or CAD packages.

    Because of its increased efficiency, speed and ease-of-use, TIMMS 2 is an effective and high-productivity indoor mapping solution for buildings and facilities of all shapes and sizes, according to Trimble, including large or small areas, multi-level, industrial or commercial spaces. Users can obtain holistic 3D indoor geospatial views of all kinds of infrastructure including public buildings (government offices, schools, hospitals); industrial facilities (factories, warehouses); transportation hubs (airports, train stations); retail spaces (malls, concourses); entertainment venues (theatres, auditoriums, sound stages); and residential property (especially multi-occupancy high-rise buildings).

    Maps and models of these spaces can be used for activities including revenue management and space planning; emergency preparedness and disaster planning; and historical building conservation and preservation. In addition, the base map provides a platform on which building owners and managers can serve location-based services.

    Manufactured and sold by Applanix, TIMMS 2 indoor mobile mapping solution is available in the first quarter of 2016.

  • Sensor Fusion by STMicroelectronics Enables 3D Navigation for Drivers

     

    STMicroelectronics is bringing next-generation satellite navigation to today’s drivers with the launch of enhanced, always-available, always-accurate 3D positioning on its TESEO III automotive-navigation integrated circuits (ICs).

    The new TESEO DRAW firmware for ST’s multi-constellation positioning chips enables navigation devices to provide continuous, accurate location and turn-by-turn instructions even when satellite signals are poor or unavailable, such as in tunnels, covered car parks, or multi-level highways. TESEO DRAW also enhances performance in built-up areas, such as in urban canyons, where conventional navigation systems can lose accuracy.

    TESEO DRAW merges the satellite information with data from vehicle sensors such as the gyroscope, accelerometer and wheel-speed sensors, to calculate location accurately in three dimensions including elevation. If the satellite signal is poor, TESEO DRAW compensates for the loss of accuracy, and if the signal becomes unavailable, navigation continues uninterrupted based on calculated location (dead reckoning). Road tests carried out by ST in difficult under-cover and urban environments have demonstrated continuous tracking from entry to exit in complex multi-level car parks, and at street level between tall buildings, where conventional systems have been unable to track the vehicle.

    By enabling high-accuracy 3D dead reckoning, TESEO DRAW expands the opportunities for developers to commercialize new applications, the company said.

     

    “TESEO DRAW strengthens GNSS performance and eliminates barriers to continuity, enabling exciting new services to emerge,” said Fabio Marchiò, Microcontroller and Infotainment Division general manager, Automotive Product Group, STMicroelectronics. “Users can also experience significant improvements in existing services such as fleet tracking, eCall, or ERA-GLONASS emergency response, usage-based insurance, road tolling, and anti-theft systems.”

    TESEO DRAW firmware has multiple modes and is capable of referring to sensors on the vehicle’s CAN bus or discrete sensors such as the odometer, reverse sensor, MEMS accelerometer and gyroscope, or MEMS inertial module connected to the TESEO III IC.

    ST is a supplier of MEMS motion sensors for automotive navigation, telematics and vehicle alarm systems, and is a provider of navigation engines with its TESEO IC family. With the launch of TESEO DRAW firmware, ST is able to provide a unified platform comprising navigation engines, 3D positioning capability and motion sensors.

    TESEO III ICs loaded with the new TESEO DRAW firmware are sampling now, and will enter mass production in Q1 2016.
