Apogee-D Dual Antenna GNSS/INS

Apogee-D: High Accuracy Dual Antenna GNSS/INS

Manufacturer: | Categories: ,

The SBG Systems Apogee-D is one of the most accurate dual GNSS/INS on the market. This highly precise Inertial Navigation System (INS) is outfitted with a dual antenna GNSS receiver for both instantaneous and post-processing operations. The Apogee-D is a MEMS-based, ITAR Free technology.



Canal Geomatics now carries the SBG Systems Apogee-D, an affordable and highly accurate inertial navigation system. This leading edge INS/GNSS incorporates the latest tri-frequency GNSS receiver supporting RTK, TerraStar and Veripos positioning services. The system comes with a dual antenna GNSS receiver, and is sure to deliver rapid alignment time and accurate heading.

The Apogee delivers a direct heave calculation, which is accurate within five centimetres. As an added benefit, there is no need to input the wave frequency, as the system detects and corrects it as required. This particular system also features a distinctive delayed heave feature for difficult sea conditions. This feature does not require any additional software, and allows for a heave calculation accurate within two centimetres and displayed with minimal delay.

The Apogee-D has several marine, land and aerospace applications. Apogee sensors are compatible with all hydrographic software, making it a great choice for the stabilization of multibeam sonar systems, the navigation of Unmanned Surface Vehicles and georeferencing, among other things.

The system is an ideal choice when precise heading is required in land vehicles, and when there is a baseline of at least ten metres. The Apogee-D can also endure GPS outages, since the GNSS/INS combination can still provide accurate positioning information when combined with an odometer. This same technology allows it to provide accurate heading during long steady flight phases, and to deliver precise position data for accurate navigation of Unmanned Aerial Vehicles and advanced payload stabilization.
