In the enhancement project for the TERRAoffice GNSS/IMU Processing Software, key functionalities were introduced to address challenges in trajectory accuracy, particularly in environments where GPS signals are unavailable. The project integrated a 'No GPS' feature, enabling the software to maintain accurate tracking using alternative data inputs. Additionally, the 'Zero Velocity Update (ZUPT)' feature was implemented to detect stationary periods, allowing for recalibration of IMU sensors and minimizing drift errors. These enhancements significantly improved the system’s performance in real-time applications.
