About Draper

System Test Facilities

GPS Simulators

  • Simulate up to 30 satellites in a highly repeatable environment
  • GPS operational and performance assessment under multipath and jamming conditions
  • User-friendly graphical user interface (GUI)
  • Trajectory can be synchronized with motion simulators for integrated system assessment


GPS RF Antenna

  • Provides coverage from 1.0 to 2.5 GHz, including L1, L2, and L5
  • Multiple feeds within Draper for testing, simulation, and clock synchronization
  • Multiple GPS antennae provide for live, multipath, and real-time kinematic tests


Hardware-in-the-Loop (HWIL) & System Integration

  • Integrated, real-time evaluation of flight hardware/software
  • Repeatable controllability and observability of all input/output to the system under test
  • Creates off-nominal conditions and tests response to fault conditions
  • Provides visualization, scenario recording, and playback
