query on clock offset ratio

hi all,

while going through [color=#333333] Single-sided two-way ranging (SS TWR) ex_6a_SS example code i found that clock offset ratio has been found using the equation[/color]
[color=#333333]" clockOffsetRatio = dwt_readcarrierintegrator() * (FREQ_OFFSET_MULTIPLIER * HERTZ_TO_PPM_MULTIPLIER_CHAN_2 / 1.0e6) ;"[/color]

[color=#333333]is clock offset ratio found here in microsecond or in ppm?[/color]

[color=#333333]is there any document describing the synchronization mechanism that can be used for WSN(wireless sensor networks) using DWM1000 or on how to analyse and rectify clock skew in WSN implimentation?[/color]

[color=#333333]please reply[/color]

I think that there is a Decawave solution that is sold like IP (Intellectual Property). So this technology is not free.

Hi Dpkpv

it probably is possible to do what you are thinking of, i.e. to use carrier integrator to help with clock sync between number of units and do TDOA, however I am not aware of any such solution… it is probably something for a R&D/PhD …
