SBG Systems releases the Apogee Series, the most accurate inertial navigation systems based on the robust and cost-effective MEMS technology. The cutting-edge Apogee Series is also the smallest and lightest inertial navigation system at this level of accuracy. High Accuracy, cost-effective, compact, the Apogee adds extreme versatility and simplicity to its many qualities.

Apogee, State-of-the-art Highly Accurate INS/GNSS

SBG SYSTEMS takes another step forward with the release of the Apogee Series, the most accurate inertial navigation systems based on the robust and cost-effective MEMS technology. This state-of-the-art INS/GNSS integrates the very last generation of MEMS sensors and Tri-frequency GNSS receiver. Apogee achieves 0.008° in roll and pitch in real-time, and 0.005° in post-processing. With two antennas, it delivers a robust and accurate heading. “SBG SYSTEMS manufactures inertial systems from the concept to the production. The Apogee benefits from our high level of expertise in integrated design, IMU calibration, testing, and filtering” declares Alexis Guinamard, CTO of SBG SYSTEMS.

Powerful & Easy-to-use INS for Hydrographic Applications

On the field of hydrography, the Apogee fits every technical need with simplicity. Lightweight and small, Apogee is easy to manipulate. In option, the SplitBox, a box with standard connectors, easily connect and synchronize all the equipment onboard of the vessel. To get the required positioning accuracy, Apogee supports RTK and every Precise Point Positioning services (Marinestar, TerraStar, etc.). Already compatible with the main hydrographic software such as QINSy or Hypack, Apogee is ready to deliver its extreme precision.

Extensive Heave Calculation for Surveying in All Sea Conditions

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. To allow surveying tasks when wave frequencies are very large or complex, Apogee comes with a delayed heave feature with no additional software nor user action. A specific algorithm allows a more extensive calculation, resulting a heave accurate to 2 cm displayed in real-time with a little delay.

Enhanced Accuracy with Post-processing

Orientation and position raw data can be recorded in the Apogee data logger. When getting back to the office, the user imports data in the post-processing software. This tool gives access to several RTK networks and reference station offline data (VRS, CORS, etc.). Additionally, it enhances orientation and position accuracy by a complete “backward/forward” calculation.

Extremely Versatile Product Line

Four models compose the Apogee line. The Apogee-A provides only orientation and heave data. The Apogee-N additionally embeds a GNSS receiver for navigation. The Apogee-D comes with two antennas for accurate heading under low dynamics conditions. Completing the line, the Apogee-E delivers navigation data when connected to an external GNSS receiver or to the SplitBox with integrated GNSS.

Apogee Series Availability

The Apogee is ITAR Free. All models are available for order. Ordering information and delivery time are available from SBG Systems representatives and authorized SBG Systems dealers. For more information about the new Apogee Series, please visit:
