Temperature Impact on Clock Stability of Ultra WideBand Chip Decawave DW1000

This paper presents the result of clock stability measurement and the temperature impact on clock stability of ultra wideband chip Decawave DW1000. It is shown that wireless one-way synchronization provides lower precision of position estimation in comparison with wired synchronization, but it is easy to realize. In the paper, implementation of linear extrapolation is presented too. The temperature stabilization of the chip does not remove requirement of synchronization, but at lower temperatures the time corrections are smaller than at higher temperatures. It was shown that it is possible to achieve acceptable precision of position estimation when wireless synchronization is used, when synchronization interval is reasonably small, usually from 10 to 100 ms, and averaging of the clock skew and the clock offset is applied with linear extrapolation method.
