* \brief Interface of an adapter of a code DLL + carrier FLL/PLL tracking
|
|
* loop for GPS L1 C/A to a TrackingInterface
|
|
* \author Javier Arribas, 2011. jarribas(at)cttc.es
|
|
*
|
|
* This is the interface of a code Delay Locked Loop (DLL) + carrier
|
|
* Phase Locked Loop (PLL) helped with a carrier Frequency Locked Loop (FLL)
|
|
* according to the algorithms described in:
|
|
* E.D. Kaplan and C. Hegarty, Understanding GPS. Principles and
|
|
* Applications, Second Edition, Artech House Publishers, 2005.
