<p>HS2 Ltd has not commissioned or used any satellite data analysis as current evidence
does not suggest they are able to detect movements in rural areas with the accuracy
required. HS2 Ltd are however investigating other analysis techniques and is reviewing
the practicality of installing corner reflectors on the ground, in order to increase
the accuracy of satellite data. Combined with other monitoring, this may enable subsequent
and more modern satellite survey data to be analysed in sufficient detail.</p>
