Struggling with high - precision time frequency in Precise Point Positioning (PPP) data processing? 😫 The huge uncertainty of the receiver clock makes it a tough nut to crack. But here's a game - changer! 🎉 A new Adaptive Clock Constraint (ACC) model has been proposed. Compared with BIPM PPP, it improves time difference STD by over 10% and frequency stability by 15%. It's suitable for different atomic clock stations too! #GNSS #PrecisePointPositioning #TimeTransfer #ReceiverClockModel #AdaptiveModel Link[doi.org/10.1080/10095020.202…]
