* \brief This class implements the receiver control plane
|
|
* \author Carlos Aviles, 2010. carlos.avilesr(at)googlemail.com
|
|
*
|
|
* GNSS Receiver Control Plane: connects the flowgraph, starts running it,
|
|
* and while it does not stop, reads the control messages generated by the blocks,
|
|
* process them, and apply the corresponding actions.
