POSPac MMS for Marine includes the Applanix SmartBase™ software module with Applanix IN-Fusion™ technology. These tools are designed to significantly increase the efficiency, accuracy, and robustness of mapping and surveying using GNSS on marine platforms. GNSS network and inertial post-processing methods work in direct cooperation, reducing and in some cases eliminating the restrictions associated with high accuracy GNSS positioning in a marine-based environment. Reliable centimetric accuracy can be obtained from existing reference station networks, even if the nearest reference station is 70 km or more away. In many scenarios, this completely eliminates the expense and logistical headaches associated with deploying a dedicated station close to the project area.

The Applanix SmartBase™ module uses the data logged from a network of GNSS reference stations to create a model of the atmospheric and other geometric errors across the survey area, and thus generate a set of GNSS observables at a “virtual” location close to the vessel. These and the remote receiver observables are then postprocessed along with data from the Inertial Measurement Unit using the Applanix IN-Fusion technology, to simultaneously solve for the GNSS ambiguities and position and orientation of the vessel. The Applanix SmartBase approach ensures errors due to atmospheric delays are accurately modelled anywhere within the network of receivers, meaning the correct integer ambiguities are quickly and reliably computed. Tight integration with inertial data improves accuracy and robustness through cycle slips or full outages.
