Inertial Navigation Systems for Infrastructure Mapping

 

Inertial Navigation Systems (INS), which typically comprise IMUs, GNSS, and sometimes additional sensors, play a critical role in providing accurate positioning, orientation, and navigation information for various applications, including mobile mapping. The data collected by mobile mapping systems often relies on INS to precisely determine the position and orientation of the mapping platform, enhancing the accuracy of the collected geospatial data.

The data garnered from an INS is pivotal for navigation, autonomous vehicle control, mapping, and georeferencing, especially benefiting aerospace, maritime, defense, and land transportation industries. When fused with systems like GNSS, INS substantially amplifies navigation accuracy and reliability, particularly under the most challenging GNSS conditions.

Using Inertial Navigation Systems (INS) in mapping infrastructure offers several advantages:

  1. Independence from External References: INS operates independently of external signals like GNSS, making it valuable in areas with signal obstructions (e.g., urban environments, tunnels) ensuring continuous navigation data.
  2. Continuous Positioning: INS provides real-time and continuous positioning, orientation, and velocity information without relying on external signals, ensuring consistent and precise data even in challenging environments.
  3. High Precision: It offers high-precision navigation data, especially in situations demanding immediate and accurate positioning, such as when inspecting underground sewers to towering power transmission structures.
  4. Adaptability: INS technology’s versatility allows it to be utilised in various vehicles, including cars, ships, aircraft, drones, and even in autonomous systems
  5. Improved Efficiency: The integration of INS in mapping technology, like RapidMap’s 360 Mobile Mapping, allows for efficient and detailed representation of infrastructure elements, streamlining asset management and maintenance.
  6. Enhanced Safety Measures: Accurate mapping helps in identifying and prioritising necessary maintenance or repairs, thereby improving safety measures for infrastructure users.
  7. Cost Reduction: Efficient mapping and accurate data facilitate better asset management and planning, reducing unnecessary expenditures by focusing on targeted repairs and maintenance.
