NavIC Galileo Long Distance RTK Positioning Performance

This research thoroughly investigates the kinematic positioning performance of the Navigation with Indian Constellation (NavIC) under static conditions, using data collected from a long baseline in India. The study compares NavIC's Single Point Positioning (SPP), long-baseline kinematic positioning, and L5 signal availability with Galileo's El and E5 signals. A Double-Differenced (DD) methodology-based kinematic model is introduced, which demonstrates that NavIC achieves centimeter-level accuracy comparable to Galileo. Although individual performance of NavIC and Galileo is inferior when used separately, their combined use significantly enhances kinematic positioning performance, surpassing the capabilities of each system individually. This combined approach offers improved accuracy and reliability in positioning, benefiting users through enhanced performance in real-world applications.
