What is the impact of changing bit rate and polarisation in (Define sensor bit rate and spatial resolution) in configuration sensor wizard?

Little impact The bit rate is used to calculate data size of each acquisition. This will be used to “qualify” each swath with a Data size parameter. It can also be used in the quota constraint, to limit the amount of planned acquisitions according to cumulated aquired volume (GBytes) See more here http://1.help.taitussoftware.com/SaVoir/help/content/6.advanced/constraints/quota/quota.htm Polarisation is […]

Regarding cloud ( if set to 0), is it that acquisition will not be planned if cloud is more that 0?

The cloud figure is a qualifier parameter, just that. The acquisition will not be planed if you have configured the sensor with a Cloud Constraint and the cloud figure is out of the defined bounds See more here: http://1.help.taitussoftware.com/SaVoir/help/content/6.advanced/constraints/clouds/clouds.htm
