SBG Systems releases the Apogee-M and the Apogee-U, two new inertial sensors to complete the Apogee product line.

The Apogee-M is a Motion Reference Unit (MRU), and the Apogee-U is an Inertial Navigation System. Both are made of titanium with a depth rating of 200m.

Apogee Series is the most accurate inertial navigation systems (INS) based on the robust and cost-effective MEMS technology. One year after the successful release of the Apogee surface sensors (IP68 enclosure), SBG SYSTEMS completes the product line with a Motion Reference Unit (MRU) and an Inertial Navigation System (INS) with a titanium subsea enclosure (200m depth rating).

The Highest Accuracy Now Available to All Hydrographic Surveyors
Apogee integrates the very latest generation of MEMS sensors to reach a high degree of precision - 0.008° in roll and pitch in real-time – while delivering a robust and accurate heading thanks to the continuous fusion of GNSS and IMU data. Made of titanium, Apogee-M and Apogee-U are ideal to mount close to the sonar head for hydrographic tasks from shallow to deep water.

Sophisticated Heave Computation
The Apogee provides a real-time heave accurate to 5 cm, which automatically detects the wave frequency and constantly adjusts to it. 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. This algorithm allows a more extensive calculation, resulting in a heave accurate to 2 cm displayed in real-time with a little delay.

Versatile, Apogee connects to every Survey-grade GNSS receiver
Apogee sensors can be paired with any type of survey-grade GNSS receiver or by the one offered by SBG SYSTEMS. The SplitBox GNSS integrates the latest tri-frequency GNSS receiver to offer several positioning features such as RTK, Marinestar, OmniSTAR, Veripos, and TerraStar corrections.

Simplicity at All Levels
Configuration is made easy throughout the intuitive embedded web interface where all parameters can be quickly displayed and adjusted. The new 3D View helps the user to check the mechanical installation, especially sensor and antennas position, alignments, and lever arms. The user can then connect the Apogee to the main hydrographic software such as Hypack, QINSy or Teledyne PDS2000 thanks to available drivers.

Long term Investment
The MEMS technology is renowned for being highly robust and low-maintenance while the subsea enclosure is made in titanium. SBG SYSTEMS continuously make its systems evolve with new firmware upgrades that are available during the whole life of the product without extra cost.
