Q1: DW1000-user-manual says SS TWR clock induces error a lot. Instead, DS TWR clock can hardly induce much error, why is SS TWR used in the latest version? Is it all because of clock offset compensation that provides SS TWR system the similar accuracy with DS TWR?
Q2: In PANS 1.0 what ranging method is used, SYMMETRIC Double-sided Two-way ranging or ASYMMETRIC Double-sided Two-way ranging? Is SYMMETRIC Double-sided Two-way ranging can be used on DWM1001 module?
Q3: In the provided white papers" Experimental-Impulse-Radio-IEEE-802.15.4a-UWB-Based-Wireless-Sensor-Localization-Technology_2015-06-01 " page 5 of 6. It says ‘Compared with the true value 1.30m measured physically using a tape, the measured instant and average distances are very accurate with only 1cm error.’ What does it mean? Does that mean DWM1001 module can measure instant distances with 1cm error? But I used pre-loaded SS TWR and DS TWR and the instant data floats about 10 centimeters.
Thank you for reading my questions. I am not quite fimilar with the module, I really appreciate it if you could discuss the problems with me.
