Apogee-E: Versatile Inertial Navigation System

HomeApogee-E: Versatile Inertial Navigation System

Apogee-E is a highly accurate Inertial Navigation System that connect to a SplitBox GNSS or any survey grade external GNSS receiver for optimal navigation. The ITAR Free Apogee-E 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-E 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-E 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 with no additional software nor user action. This specific algorithm allows a more extensive calculation, resulting in a heave accurate to 2 cm displayed in real-time with a little delay.



The Apogee-E can be connected to your own GPS/GNSS receiver and access RTK and Precise Point Positioning (PPP) services through your receiver or through the SplitBox GNSS (TerrasStar, OmniSTAR). It delivers reliable position thanks to its tight integration of Inertial Sensors, GNSS and Odometer data.


Apogee-E has been designed to be integrated in a new or already exhisting aerial mapping system. It can either use your own GNSS receiver, or the one embedded in the SplitBox GNSS, to deliver unmatched position and orientation accuracy. Thanks to its very low noise gyroscopes, it provides extremely accurate data for advanced LiDAR data georeferencing.

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.
