· Non-optimised multi-dwell acquisition with fine doppler estimation is now enabled in the block factory (It is used by the front-end calibration utility). It can be instantiated from the configuration file.

· Bug fixed in the configuration parser that prevented the use of non-integer thresholds
· Provisional patch added to disable the PVT output if the height is above 50 km (due to a random bug that appears with some satellite configurations..)
