Description

Apogee-N is a highly accurate Inertial Navigation System with embedded GNSS receiver for real-time and post-processing operations.

The ITAR-Free Apogee-N is the most accurate INS/GNSS based on the robust and cost-effective MEMS technology.

High Accuracy:

  • 0.008° Roll & Pitch (RTK)
  • 0.04°   GNSS-based Heading (RTK)
  • 1 cm    Position (RTK)
  • Post-processing with Qinertia INS/GNSS PPK Software
  • 5 cm    Real-time Heave
  • 2 cm    Delayed Heave

 

Apogee-N embeds:

  • The latest MEMS gyroscopes and accelerometers
  • The latest tri-frequency GNSS receiver with one Survey grade antenna
  • A Web Interface for Easy Configuration
  • A 48h Internal Data Logger for Post-processing

Apogee Models Available

The Latest Tri-frequency GNSS receiver – RTK, TerraStar, Veripos Positioning

This state-of-the-art INS/GNSS integrates the last generation of Tri-frequency GNSS receiver which supports RTK, TerraStar and Veripos positioning services. It is the smallest and lightest integrated inertial navigation system at this level of performance.

 

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.

Applications

Land

Apogee-N is an all-in-one solution that provides accurate trajectory even in urban canyons, forest, or tunnel. It handles GPS outages thanks to a tight integration of inertial, GNSS, and odometer information. Apogee-N is a smart choice for all advanced Land Mobile Mapping application.

 

Aerospace

Apogee-N is the ultimate INS for Aerial Mapping, Photogrammetry or Remote Sensing projects. Thanks to its very low noise gyroscopes, it delivers accurate and stable orientation and position data, both real time or post processing. It’s also a cutting edge solution for strategic UAV navigation and advanced payload stabilization.

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.).
