UltraNav Guide #3: Enhancing Data Accuracy with Applanix POSPac
11 March 2025
In our series on the UltraNav system—the all-in-one flight management, georeferencing, and post-processing solution for airborne data capture—we’re diving deeper into one of its critical components: the Applanix POSPac Solution. As an integral part of the UltraNav ecosystem, POSPac MMS plays a vital role in ensuring the precision and reliability of geospatial data collected during airborne missions. Let’s explore how it works and why it’s a game-changer for your aerial projects.
POSPac® MMS (Mobile Mapping Suite), the industry-leading software for direct georeferencing of mobile mapping sensors, utilizes GNSS and inertial technology. Supporting GNSS-inertial trajectory post-processing in land, airborne, and marine mapping sector, the software refines raw GNSS and inertial data logged during mapping missions to achieve the highest accuracy in position and orientation. This precise direct-georeferencing is essential for generating reliable and actionable insights from imagery data.
For UltraNav users, POSPac seamlessly integrates with the system, enhancing the overall workflow from flight planning to data delivery.
Key Features of Applanix POSPac in UltraNav
- Direct Georeferencing Accuracy
POSPac utilizes advanced processing algorithms, including the latest IN-Fusion+ technology and Post-Processed CenterPointⓇ RTX, to deliver precise direct georeferencing results. This process ensures that each image pixel is assigned an accurate 3D position, thereby eliminating the necessity for numerous ground control points (GCPs). -
PP-RTX Technology for Global Accuracy
The cloud-based global GNSS Post-Processed CenterPointⓇ RTX (PP-RTX) correction service enables UltraNav users to achieve centimeter-level accuracy without base stations, within minutes after flight mission completion. While this is applicable to any airborne missions globally, it is particularly useful in areas with limited or no access to ground-based infrastructure, such as remote regions or complex terrains.Learn more about the cloud-based global GNSS correction service in UltraNav here and study the White Paper about IN-Fusion PP-RTX for Crewed Airborne.
- Robust Error Correction
POSPac effectively and precisely merges GNSS and inertial data, minimizing the GNSS error budget caused by atmospheric delays and multipath effects. This results in reliable data, even in challenging environments.
- Efficient Workflow Integration
POSPac is designed for efficiency, enabling seamless integration with UltraNav. This reduces the time between data collection and project delivery, optimizing your workflow.
In addition to traditional methods that rely on base stations (Single Base or SmartBase mode), Applanix leverages Trimble’s CenterPointⓇ RTX correction service in post-processing mode. Learn more.
