Apogee-U

 

Apogee-U: Inertial Navigation System with Subsea Housing

Apogee-U is a highly accurate Inertial Navigation System, with a titanium subsea housing. It connects to a SplitBox GNSS or any survey grade external GNSS receiver for navigation. The ITAR Free Apogee-U is the most accurate and versatile INS based on the robust and cost-effective MEMS technology.

High Accuracy:

  • 0.008° Roll & Pitch (RTK)
  • 0.025° GNSS-based Heading  (4m baseline)
  • 1 cm    Position (Depends on GNSS receiver)
  • Post-processing with Qinertia INS/GNSS PPK Software
  • 5 cm    Real-time Heave
  • 2 cm    Delayed Heave

Apogee-U embeds:

  • The latest MEMS gyroscopes and accelerometers
  • A Web Interface for Easy Configuration
  • A 48h Internal Data Logger for Post-processing
  • Positioning with an External GNSS receiver

    The Apogee-U connects to any survey grade GPS/GNSS receiver to provide navigation data. GNSS information is fused in real-time with inertial data to provide the best performance. It features a unique GNSS error model to take into account every receiver specific behaviors.

    Positioning with a SplitBox GNSS

    The SplitBox GNSS integrates the latest generation tri-frequency GNSS receiver that supports RTK and Precise Point Positioning (Marinestar, TerraStar, Veripos, OmniSTAR, etc.). It also provides raw data for Post-Processing. The SplitBox GNSS embeds a Dual Antenna receiver for highly accurate and robust heading in every dynamic conditions.

    Extensive Heave Calculation

    The Apogee provides a real-time heave accurate to 5 cm. For more simplicity, the user doesn’t have to enter the wave frequency; the Apogee automatically detects it and constantly adjusts to it.

    Apogee comes also with a unique delayed heave feature resulting in a heave accurate to 2 cm displayed in real-time with a little delay. When wave frequency is erratic or in case of long period swell, the delayed heave feature can save the day by allowing survey in rough conditions.

    Easy Configuration

     

    Web Interface with 3D View

    Configuration is made easy throughout our intuitive embedded web interface where all parameters can be quickly displayed and adjusted. The new 3D View helps you to check your mechanical installation, especially your sensor position, your alignments, and lever arms.

    Applications

     

    From Shallow to Deep Water Hydrography

     

    Apogee-U combined with the SplitBox GNSS is the perfect solution for  hydrographic applications from shallow to deep water. Easy to install, Apogee is already compatible with Hypack, QINsy, and Teledyne PDS 2000 software. Use the Delayed Heave feature to survey in the worst sea conditions. Combined with an available PPP service (Marinstar, TerraStar, Veripos), it provides a 10 cm position accuracy.

    Complementary Equipment and Software

     

    Connection, Synchronization, and Positioning

    The SplitBox provides a simplified interface for easy connection and synchronization with external equipment such as odometer, differential corrections, computers, or survey instruments. The SplitBox with integrated GNSS receiver additionally delivers navigation data with a large choice of positioning services (Marinestar, TerraStar, etc.).

    Qinertia INS/GNSS Post-processing Software

     

    Qinertia is the SBG Systems in-house post-processing software. This full-featured software enhances SBG inertial navigation systems performance by post processing inertial data with raw GNSS observables.
