Reliability of Real-Time Kinematic (RTK) Positioning for Low-Cost Drones' Navigation across Global Navigation Satellite System (GNSS) Critical Environments. [PDF]
Sensors (Basel)UAVs are nowadays used for several surveying activities, some of which imply flying close to tall walls, in and out of tunnels, under bridges, and so forth. In these applications, RTK GNSS positioning delivers results with very variable quality.

Applied SciencesIn complex urban road environments, vehicles inevitably experience frequent or sustained interruptions of the Global Navigation Satellite System (GNSS) signal when passing through overpasses, near tall buildings, and through tunnels. This results in the reduced accuracy and robustness of the GNSS/Inertial Navigation System (INS) integrated navigation ...

Breaking Through GNSS Outage: Advanced Stochastic Model for MEMS IMU in Navigation
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingInertial navigation systems (INS) are widely recognized for providing precise location, velocity, and attitude data over short durations. However, their accuracy deteriorates over time. To maintain accurate navigation, it is crucial to characterize and model both deterministic and stochastic error components of inertial sensors.

Automated archiving of archaeological aerial images [PDF]
, 2016 The main purpose of any aerial photo archive is to allow quick access to images based on content and location. Therefore, next to a description of technical parameters and depicted content, georeferencing of every image is of vital importance.

Performance Analysis of Constrained Loosely Coupled GPS/INS Integration Solutions [PDF]
, 2012 The paper investigates approaches for loosely coupled GPS/INS integration. Error performance is calculated using a reference trajectory. A performance improvement can be obtained by exploiting additional map information (for example, a road boundary).
