  • Rockwell Collins Taps Spirent for GPS Wing Contract

    Spirent Federal Systems Inc. said today that Rockwell Collins has selected Spirent Federal to supply multiple GPS simulators to support the Modernized User Equipment (MUE) Receiver Card Development contract it has with the GPS Wing.

    The GPS modernization effort is a system-wide program that includes upgrades to the space, control and user segments.

    The award includes Spirent Federal’s GSS7700 Series GPS Simulator, fully approved classified package, interface/jamming and Advanced Encryption Standard (AES) M-Code and Simulator Data Sets (SDS) M-Code capability. Spirent Federal has already received the Global Positioning Systems Wing security approval for its SDS Upgrade Package for the GSS7700 GPS Simulator last month; it is the first company to obtain security approval for a simulator that meets all the requirements for MUE, including the new SDS M-Code capabilities, the company says.

    Spirent manufactures an extensive range of GPS test equipment, from simple production test units for the commercial market to the GSS7700 series for more technically demanding applications. Configurations include GPS L1 only, dual-frequency L1/L2 (including L2C), L5, a fully approved classified package, Satellite Based Augmentation Systems (SBAS), interface/jamming simulation, inertial interfaces, Hardware in the Loop (HIL) test capability, high dynamic capability, and M-Code. Spirent Federal also offers Russian GLONASS simulation and European Galileo simulation.

  • Spirent Intros Customizable Software for GPS Test, Simulation

    Navigation and positioning test system supplier Spirent Communications this week introduced a software suite for the STR4500 GPS simulator, enabling users to generate their own test cases based on motion data that fits their specific requirements, the company said.

    Launched in 2001, the STR4500 provides pre-defined test cases for the testing of GPS receivers and systems to be replayed using a PC-based controller with RF signal generator hardware. Typical users of the STR4500 are involved with the selection, integration, verification or production test of GPS L1 C/A code systems, according to Spirent.

    The new SimPLEX45 software enables unique test cases to be generated, saved and run directly by the user. SimPLEX45 also enables user-defined motion-data to be used with atmospheric models and the environment around a vehicle, the company said.

    “This new software will enable our customers to drive a route and, using logged NMEA data, generate a trajectory for a test case,” stated John Pottle, marketing director for Spirent’s Wireless and Positioning Division. “The user also will be able to define the antenna pattern, atmospheric effect and obscuration due to buildings or other obstructions. We’ve built this capability into the STR4500 to provide our customers with reduced development times via improved tailoring of test scenarios to fit their specific needs.”

    The SimPLEX45 is available with new systems or as an easy to install upgrade to existing STR4500 users, Spirent said.
