Constructor & Destructor Documentation
◆ GPSCNavAlm()
| gnsstk::GPSCNavAlm::GPSCNavAlm | ( | ) |
Sets the nav message type.
Definition at line 46 of file GPSCNavAlm.cpp.
Member Function Documentation
◆ clone()
|
inlineoverridevirtual |
Create a deep copy of this object.
Implements gnsstk::NavData.
Reimplemented in gnsstk::GPSCNavRedAlm.
Definition at line 56 of file GPSCNavAlm.hpp.
◆ dumpHarmonics()
|
inlineoverridevirtual |
Override dumpHarmonics to hide them in output since GPS CNav almanacs don't contain this data.
Reimplemented from gnsstk::OrbitDataKepler.
Definition at line 78 of file GPSCNavAlm.hpp.
◆ fixFit()
| void gnsstk::GPSCNavAlm::fixFit | ( | ) |
Fill the beginFit and endFit values for this object.
- Todo:
- Determine a more reasonable set of values. This was copied from OrbAlmExt.
Definition at line 75 of file GPSCNavAlm.cpp.
◆ getUserTime()
|
overridevirtual |
Returns the time when the navigation message would have first been available to the user equipment, i.e. the time at which the final bit of a given broadcast navigation message is received. This is used by NavDataFactoryWithStore::find() in User mode.
- Returns
- transmit time + 12s or 6s, depending on whether this is CNAV on L5 or on L2.
Reimplemented from gnsstk::NavData.
Definition at line 66 of file GPSCNavAlm.cpp.
◆ validate()
|
overridevirtual |
Checks the contents of this message against known validity rules as defined in the appropriate ICD.
- Todo:
- implement some checking.
- Returns
- true if this message is valid according to ICD criteria.
Implements gnsstk::NavData.
Reimplemented in gnsstk::GPSCNavRedAlm.
Definition at line 59 of file GPSCNavAlm.cpp.

◆ healthL1
| bool gnsstk::GPSCNavAlm::healthL1 |
L1 signal health from message type 10.

L5 signal health from message type 10.
Definition at line 87 of file GPSCNavAlm.hpp.
◆ toa
| double gnsstk::GPSCNavAlm::toa |
Convenience storage of unqualified toa.
Definition at line 90 of file GPSCNavAlm.hpp.
◆ wna
| unsigned gnsstk::GPSCNavAlm::wna |
Reference week for toa.
Definition at line 89 of file GPSCNavAlm.hpp.
