Lockheed Martin and Raytheon Complete First Launch Exercise for Next Generation GPS Satellites

Press release:


Lockheed Martin and Raytheon Complete First Launch Exercise for Next Generation GPS Satellites

NEWTOWN, Pa., September 5, 2012 – Raytheon Company [NYSE: RTN] and Lockheed Martin [NYSE: LMT] have successfully completed the first launch readiness exercise for the U.S. Air Force’s next generation GPS III satellites. The exercise is a key milestone demonstrating the team remains on schedule to achieve launch availability in 2014.
The Lockheed Martin-built GPS III satellites and the Raytheon-developed next generation GPS operational control system, known as OCX, are critical elements of the U.S. Air Force’s effort to affordably replace aging GPS satellites while improving capability to meet the evolving demands of military, commercial and civilian users worldwide. This is the first space and ground enterprise successfully building the ground control and space vehicles by two independent prime contractors.
The launch readiness exercise, completed over a three day period by mission operations personnel, validated the basic satellite command and control functions, tested the software and hardware interfaces and demonstratedbasic on-console procedures required for space vehicle contacts during the launch and early orbit mission.  The event sets the stage for the first GPS III satellite’s mission readiness timeline, which includes five short-duration exercises and six, five day mission rehearsals leading up tolaunch.
“Completion of our first GPS III launch readiness exercise is a major milestone for the entire GPS enterprise and is a solid indictor that our space and ground segments are well synchronized,” said Col Bernie Gruber, the director of the U.S. Air Force’s Global Positioning Systems Directorate.
To achieve first launch availability in the 2014 timeframe, the U.S. Air Force awarded Lockheed Martin and Raytheon contracts in January of this year to provide a Launch and Checkout Capability (LCC) for launch and early on-orbit testing of all GPS III satellites.  At the heart of the LCC is Raytheon’s Launch and Checkout System that will provide satellite command and control capability, an integral part of OCX’s  support of the first GPS III launch.
“The completion of our first launch readiness exercise is an important milestone for the entire GPS enterprise,” said Keoki Jackson, vice president of Lockheed Martin’s Navigation Systems mission area. “This achievement is a testament to efficient planning and synchronization by theU.S. Air Force and demonstrates that we are on track to deliver critical GPS III capabilities to military, commercial and civilian users worldwide.”
“This milestone represents the hard work and dedication of the entire GPS III and OCX government-industry team,” stated Ray Kolibaba, a vice president of Raytheon’s Intelligence and Information Systems business and GPS OCX program manager. “This is another demonstration of the rapid progress we’re making on OCX development, while maintaining GPS space-ground enterprise alignment. I’m confident that we'll be prepared to support the first GPS III launch with an efficient, evolvable and secure ground control system built independently.”
The GPS III team is led by the Global Positioning Systems Directorate at the U.S. Air Force Space and Missile Systems Center. Air Force Space Command, based at Schriever Air Force Base, Colo., manages and operates the GPS constellation for both civil and military users.

Broadcom Introduces New Location Architecture

Broadcom Introduces New Location Architecture with Advanced Multi-Constellation and Indoor Positioning Support

Smartphone Location Platform Delivers 10X Improved Acquisition Performance and Leverages Broadcom Wireless Connectivity for Indoor Positioning

IRVINE, Calif.March 21, 2012 /PRNewswire/ --
News Highlights:
  • 10x acquisition performance improvement delivers faster and more accurate position computation
  • Leading 40nm CMOS process reduces power consumption by 50 percent and board area by 44 percent
  • Ability to leverage sensors, Wi-Fi, Bluetooth and NFC enables innovative consumer applications
  • Integration on recently announced Broadcom BCM28155 platform brings feature-rich location functionality to Android 4.0 smartphones
Broadcom Corporation (NASDAQ: BRCM), a global innovation leader in semiconductor solutions for wired and wireless communications, today introduced a new location architecture to provide more responsive outdoor and indoor positioning capabilities for smartphone devices. With proven third-generation multi-constellation support and tight integration with sensor components and Broadcom's industry-leading connectivity sub-system, the new solution opens the door to innovative applications, such as indoor positioning and place-based mobile commerce. For more news, visit Broadcom'sNewsroom.
The architecture features a new Global Navigation Satellite System (GNSS) chip that significantly reduces time-to-first-fix (TTFF) for outdoor positioning applications, cutting the time smartphone users have to wait when first checking their position. The platform solution also uses data from inertial sensors, Wi-Fi access points (including those based on recently announced 5G WiFi) and future technologies such as Bluetooth beacons to enable ground breaking indoor positioning capabilities, such as "personal shopper" applications that can direct users to specific stores within shopping malls, and even specific shelves within those stores. In addition, platform integration with NFC enables smarter, more secure mobile payments, with users able to specify countries, cities or even stores where digital wallets can be used. 
The Broadcom® BCM4752 GNSS chip provides the industry's most advanced multi-constellation support by simultaneously collecting data from four satellite constellations (GPS, GLONASS, QZSS and SBAS) and using the best received signals, resulting in faster searches and more accurate real-time navigation. Building on the success of previous GNSS chips, Broadcom's multi-constellation technology, coupled with advanced signal processing, provides faster positioning performance for improved user experience, especially in challenging urban environments where buildings and obstructions can dramatically impact accuracy and time-to-fix.
The new chip and accompanying software benefit from tight integration with Broadcom's InConcert® wireless connectivity sub-system, featuring the most advanced and complete technology offering in the industry. By developing its various connectivity components to operate as a unified system, Broadcom can offer more expansive location features that extend beyond GNSS capabilities.
Key Features and Benefits:
  • Enhances performance and reliability:
    • Industry-breakthrough acquisition engine with advanced multipath mitigation techniques provides faster time-to-first-fix performance in challenging environments, as well as a more accurate urban navigation experience.
    • Multi-constellation capability collects data from four satellite constellations (GPS, GLONASS, QZSS and SBAS) simultaneously and uses the best received signals, resulting in faster signal searches and more accurate real-time navigation.
  • Lowest board space, power consumption and cost:
    • Fabricated in 40nm process, the BCM4752 is the industry's smallest size GNSS chip, accounting for 44 percent less board space in a device.
    • Integration of key components such a low noise amplifier (LNA) enables lowest bill of materials cost.
    • The BCM4752 uses 50 percent less power than previous generations, allowing location-aware applications to remain active for longer periods of time. 
    • New applications such as "geofencing" that provide alerts or services based on location can be completely off-loaded from the smartphone's CPU for ultra-low system power operation.
  • Opens doors to new applications, with a proven software platform capable of:
    • Ground-breaking indoor positioning through integration of Wi-Fi (including 5G WiFi), Bluetooth low energy, NFC and handset inertial sensor data into positioning applications.
    • Industry-leading urban navigation by applying handset inertial sensor readings into the position computation.
    • Best in class assisted GNSS (AGNSS) with both GPS and GLONASS assistance data available worldwide fromBroadcom's hosted reference network.
