    SBG Systems has added a new inertial system to its Ekinox Series. With integrated Dual Antenna GPS + GLONASS receiver, the Ekinox-D is a ready-to-use survey-grade inertial navigation system that provides consistent true heading (0.05°), SBG Systems said.

    The Ekinox-D is a high-performance inertial navigation system that embeds a dual-antenna L1/L2 GNSS receiver to deliver more robust heading and position, while increasing satellite reception availability. Ekinox-D is an integrated system: GNSS data and inertial information are fused by an Extended Kalman Filter (EKF) to improve data integrity. This computation allows the system to achieve 0.05° roll, pitch, and true heading; 5-cm heave; and 2-cm RTK GNSS position.

    The Ekinox-D is an all-in-one Solution for demanding applications. Instead of mounting separate GNSS receiver and inertial systems on a boat, car, or plane, the Ekinox-D can be installed and connect it to a  camera, SONAR, or LiDAR system. With its 8-GB datalogger and its high output rate (200 Hz), Ekinox-D joins simplicity and performance for applications where robust heading is required such as surveying and hydrographic applications, unmanned system navigation, and auto testing.

    The IP68 Ekinox Series brings robust, maintenance free, and cost-effective MEMS to the next level thanks to a drastic selection of high-end MEMS sensors, an advanced calibration procedure, and powerful algorithm design, SBG Systems said, adding that compromise is no longer required between high accuracy and cost.

  • Satelles Announces Patent and Technology License Agreement with Boeing

    Satelles, a division of iKare Corporation, has entered into a patent and technology license agreement with The Boeing Company. This license allows Satelles to provide timing and location solutions to commercial markets delivered over the Iridium constellation of 66 low-Earth-orbiting satellites.

    The timing and location signals are available anywhere on Earth, without the need for local infrastructure, making the system perfect for augmenting GPS and other location-based technologies, Satelles said. Unlike standard GPS, the high-power signals can reach into many building structures. The signal-in-space provides a location-specific signature that can reliably prove (or authenticate) the location of a mobile device or other equipment, while being virtually impervious to spoofing and other attacks, Satelles said.

    Gregory Gutt, CEO of iKare Corporation, stated, “After working closely with Boeing for years to create a global indoor-positioning solution, we are thrilled to be entering this license agreement, which includes over 30 issued and pending patents.”

    Michael O’Connor, CEO of the Satelles business, agreed. “We see tremendous dual use potential for the technology going forward. Indoor location is an exciting area, and we are seeing keen commercial interest in a solution that delivers trusted location for secure network communication or network transaction security.”

    Satelles is headquartered in Silicon Valley, in Redwood City, California, with an office in Ashburn, Virginia.

  • GPS Source Receives USAF GPS Directorate Approval for GLI-FLO

    GPS Source Receives USAF GPS Directorate Approval for GLI-FLO

    GPSSource's GLI-FLO receiver.
    GPS Source’s GLI-FLO.

    GPS Source announced today that GLI-FLO has been granted security approval by the U.S. Air Force Global Positioning Systems Directorate. The GPS Directorate security approval provides GPS Source with the opportunity to supply military end-users and prime contractors with a DAGR Distributed Device (D3) that meets the mandate for reliability and security, GPS Source said.

    GLI-FLO is a secure (ICD-GPS-153 compliant) GPS position, navigation, and timing (PNT) distribution device. One GLI-FLO has the same capability as four DAGRs operating in a platform mounted application (eight DAGRs with custom cabling). GLI-FLO serves ICD-GPS-153 PNT data simultaneously to multiple communication or weapon systems that require GPS information. It routes PNT data while secured in the bracket now used by the DAGR, utilizing standard DAGR accessory cables. When GLI-FLO is connected to one DAGR (or as alternative option, interfaces with an internal secure GPS receiver), secure PNT data can be distributed without the integration of GB-GRAM cards to multiple devices.

    GLI-FLO meets the stringent requirements for reliability and security by integrating a GPS Directorate-approved SAASM receiver (Selective Availability/Anti-Spoofing Module). SAASM is the security architecture selected by the Joint Chiefs of Staff (JCS) to provide current security functions for GPS-authorized military users.

    “We understand the importance of reliable GPS/PNT data for synchronizing military operations and the need to protect against jamming and/or spoofing,” said Robert Horton, CEO of GPS Source. “We further realize the importance of protecting our national assets by designing products that fully comply with all GPS Directorate security requirements. This security approval makes it possible for our GLI-FLO to be deployed by military forces without reservation.”

    In addition to the SAASM compliance, other GLI-FLO features include the ability to serve ICD-GPS-153 PNT data simultaneously to multiple communications or weapon systems that require secure GPS information. It is a significant step for GPS Source toward compliance in GPS Signal Distribution (Single PNT Distribution Point). With zero impact to subscriber application software/hardware, it removes the need to rely on multiple, expensive GB-GRAMS found in military platforms.

    Lockheed Martin has delivered a full-sized, functional prototype of the next-generation GPS satellite to Cape Canaveral Air Force Station to test facilities and pre-launch processes in advance of the arrival of the first GPS III flight satellite.

    The GPS III Non-Flight Satellite Testbed (GNST) arrived at the Cape on July 19 to begin to dry run launch-base space-vehicle processing activities and other testing that future flight GPS III satellites will undergo. The first flight GPS III satellite is expected to arrive at the Cape in 2014, ready for launch by the U.S. Air Force in 2015.

    The GNST arrived at the Cape by Air Force C-17 aircraft from Buckley Air Force Base near Lockheed Martin’s GPS III Processing Facility (GPF) in Denver, Colorado. Prior to shipment, the GNST was developed and then completed a series of high-fidelity activities to pathfind the integration, test and environmental checkout that all production GPS III satellites undergo at Lockheed Martin’s new satellite manufacturing facility.

    An innovative investment by the Air Force under the original GPS III development contract, the GNST has helped to identify and resolve development issues prior to integration and test of the first GPS III flight space vehicle (SV 01).  Following the Air Force’s rigorous “back-to-basics” acquisition approach, the GNST has gone through the development, test and production process for the GPS III program first, significantly reducing risk for the flight vehicles, improving production predictability, increasing mission assurance and lowering overall program costs.

    “We call the GNST a ‘pathfinder’ because it has truly blazed the trail for every one of our GPS III processes from initial development, production, integration and test, and now pre-launch activities,” explained Keoki Jackson, vice president for Lockheed Martin’s Navigation Systems mission area. “All future GPS III satellites will follow this same path, so the GNST was a smart initiative to help us discover and resolve any issues in advance, implement production efficiencies, and ultimately save a tremendous amount of time and money in the long run.”

    GPS III is a critically important program for the Air Force, affordably replacing aging GPS satellites in orbit, while improving capability to meet the evolving demands of military, commercial and civilian users. GPS III satellites will deliver three times better accuracy, include enhancements which extend spacecraft life 25 percent further than the prior GPS block, and a new civil signal designed to be interoperable with international global navigation satellite systems.

    Lockheed Martin is currently under contract for production of the first four GPS III satellites (SV 01-04), and has received advanced procurement funding for long-lead components for the fifth, sixth, seventh and eighth satellites (SV 05-08).

    To increase real-time positional accuracy, the Juno T41 G configuration provides enhanced, 1-2 meter GPS acquisition capability and it can be combined with other Juno T41 configurations, including the smartphone or the 1D/2D Imager.

    The Juno T41 G supports the GPS L1 band and offers reliable performance in reduced signal environments. Workers who have to move from place to place to collect remote assets won’t have to waste time waiting for a system warm-up: the Juno T41 G tests at an average cold start of less than 38 seconds, and a warm start of less than 6 seconds. The G configuration handheld collects data in real-time at 1-2 meter accuracy, while also capturing Raw Data Output for post-processing applications. The Juno T41 G is designed to work with Satellite Based Augmentation Systems (SBAS), third-party Real-Time Networks (RTN), and corrections services from Trimble.

    Trimble Scan technology in the Juno T41 S reads a variety of traditional 1D barcodes as well as 2D matrix codes, and captures signatures and images. These features are customizable using the Trimble “Scan Agent” application. Enterprises can also use the Software Development Kit (SDK) to optimize applications to meet specific customer needs. Omni-directional reading capabilities along with high-motion tolerance allow for rapid, accurate scanning from virtually any angle or orientation from the handheld to the barcodes.

    With these additions, the Juno T41 rugged handheld series has a configuration that can meet a wide variety of business needs in a single rugged device, Trimble said.
