30 Jan 2020: Dr. Zaineb Farooq discussed her recently completed PhD work on the topic - Precise localization using Global Navigation Satellite Systems (GNSS). She discussed the concept of positioning using GNSS measurements. The prevalent schemes for precise positioning using GNSS measurements, namely Precise Point Positioning (PPP) and Real Time Kinematic (RTK) were introduced. This was followed by the problem of cycle slips in RTK and ways to mitigate it. Using single frequency GNSS receivers, it was seen that once cycle slips are detected and corresponding measurements taken care of, cm level positioning accuracy can be achieved. Finally, the applications of low cost single frequency receivers in precise positioning were presented. The talk was followed by an interactive discussion on other use cases including indoor localization etc.
