Detailed Description
This class encapsulates data for satellite orbits and clocks, including positions, velocities and other orbit and estimation information read as found in I/O of SP3 format (versions a, b, c, or d) files.
This class is used in conjuction with class SP3Stream, which handles the I/O, and SP3Header, which holds information from the SP3 file header. Note that the version of SP3 is stored ONLY in the SP3Header object. This version is set when an SP3 header is read into SP3Header, and it may be set by the user using SP3Header::setVersion(). On output, SP3Stream uses the version stored in the SP3Header to determine how SP3Data (this object) is output.
- See also
- gnsstk::SP3Header and gnsstk::SP3Stream for more information.
- petest.cpp for an example.

Member Function Documentation
◆ dump()
|
virtualnoexcept |
Debug output function.
Definition at line 413 of file SP3Data.cpp.
◆ isData()
|
inlinevirtual |
SP3Data is "data" so this function always returns true.
Reimplemented from gnsstk::FFData.
Definition at line 111 of file SP3Data.hpp.
◆ reallyGetRecord()
|
protectedvirtual |
This function reads a record from the given FFStream. If an error is encountered in retrieving the record, the stream is reset to its original position and its fail-bit is set.
- Exceptions
-
std::exception StringException when a StringUtils function fails FFStreamError when exceptions(failbit) is set and a read or formatting error occurs. This also resets the stream to its pre-read position.
Implements gnsstk::FFData.
Definition at line 54 of file SP3Data.cpp.
◆ reallyPutRecord()
|
protectedvirtual |
Writes the formatted record to the FFStream s.
- Exceptions
-
std::exception FFStreamError StringUtils::StringException
Implements gnsstk::FFData.
Definition at line 324 of file SP3Data.cpp.
