SBG Systems has released 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 200 meters. 

 

Apogee Series is an inertial navigation systems (INS) based on the MEMS technology. One year after the release of the Apogee surface sensors (IP68 enclosure), SBG Systems has completed the product line with a Motion Reference Unit (MRU) and an Inertial Navigation System (INS) with a titanium subsea enclosure (200-meter depth rating).

 

According to its developer, Apogee integrates the 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 suited to mount close to the sonar head for hydrographic tasks from shallow to deep water.

 

The Apogee provides a real-time heave accurate to 5 centimeters, which automatically detects the wave frequency and constantly adjusts to it, SBG Systems said. 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 centimeters displayed in real-time with a little delay.

 

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. 

 

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.

 

SBG Systems continuously make its systems evolve with new firmware upgrades that are available during the whole life of the product without extra cost. 

 

Apogee-M and Apogee-U are ITAR Free. All models are available for order.
