New tracking libraries:
- tracking_discriminators: Library with a set of code tracking and carrier tracking discriminators that is used by the tracking algorithms. (fully documented, including math algorithms using doxygen!)
- tracking_2rd_DLL_filter: Class that implements 2 order DLL filter for code tracking loop.
- tracking_2rd_PLL_filter: Class that implements 2 order PLL filter for carrier tracking loop.
- tracking_FLL_PLL_filter: Class that implements hybrid FLL and PLL filter for tracking carrier loop.
- CN_estimators: Library with a set of Carrier to Noise estimators and lock detectors. (fully documented, including math algorithms using doxygen!)
Tracking:
- gps_l1_ca_dll_pll_tracking: The existing DLL + PLL tracking module, which is the K.Borre and D.Akos one, is now completely re-factored. Now uses the above described libraries.
- gps_l1_ca_dll_fll_pll_tracking: This is a brand new tracking module, which implements the FLL assisted PLL described in Kaplan (2nd edition). (also documentedwith references)
Configuration options:
- The following tracking parameters are added:
;######### TRACKING CONFIG ############
; Tracking.implementation=GPS_L1_CA_DLL_PLL_Tracking or GPS_L1_CA_DLL_FLL_PLL_Tracking
Tracking.implementation=GPS_L1_CA_DLL_FLL_PLL_Tracking
;PLL filter bandwidth in Hz.
Tracking.pll_bw_hz=50.0;
;DLL filter bandwidth in Hz.
Tracking.dll_bw_hz=2.0;
;FLL filter bandwidth in Hz.
Tracking.fll_bw_hz=50;
;filter order: choice between 2 or 3 at this moment, only for FLL assisted PLL
Tracking.order=2;
;Correlator space in chips units
Tracking.early_late_space_chips=0.5;
Other files have also been modified with minor changes to adapt to new modules or minor bug fixes.
