◆ convertAutoCovariance()

◆ convertCovariance()

double parsing_utilities::convertCovariance ( double val )

inline

Definition at line 529 of file parsing_utilities.hpp.

◆ convertDMSToDegrees()

double parsing_utilities::convertDMSToDegrees ( double dms )

Converts latitude or longitude from the DMS notation (in the without-colon-delimiter format), to the pure degree notation.

Note that DMS stands for "Degrees, Minutes, Seconds".

Parameters

[in] dms Represents latitude or longitude in the DMS notation (in the without-colon-delimiter format)

Returns: Represents latitude or longitude in the pure degree notation

Recall: One degree is divided into 60 minutes (of arc), and in turn one minute into 60 seconds (of arc). Use of the degrees-minutes-seconds system is also called DMS notation.

Definition at line 235 of file parsing_utilities.cpp.

◆ convertEulerToQuaternion()

Eigen::Quaterniond parsing_utilities::convertEulerToQuaternion	(	double	roll,
		double	pitch,
		double	yaw
	)

inline

Transforms Euler angles to a quaternion.

Parameters

[in]	yaw	Yaw, i.e. heading, about the z-axis [rad]
[in]	pitch	Pitch about the new y-axis [rad]
[in]	roll	Roll about the new y-axis [rad]

Returns: quaternion The rotational sequence convention we adopt here (and Septentrio receivers' pitch, roll, yaw definition too) is the yaw-pitch-roll sequence, i.e. the 3-2-1 sequence: The body first does yaw around the z-axis, then pitches around the new y-axis and finally rolls around the new x-axis.

Definition at line 326 of file parsing_utilities.hpp.

◆ convertEulerToQuaternionMsg()

QuaternionMsg parsing_utilities::convertEulerToQuaternionMsg	(	double	roll,
		double	pitch,
		double	yaw
	)

Parameters

[in] q Eigen quaternion

Returns: ROS message representing a quaternion

Definition at line 366 of file parsing_utilities.hpp.

◆ convertUserPeriodToRxCommand()

std::string parsing_utilities::convertUserPeriodToRxCommand ( uint32_t period_user )

Transforms the input polling period [milliseconds] into a std::string number that can be appended to either sec or msec for Rx commands.

Parameters

[in] period_user Polling period in milliseconds as specified by the ROSaic user

Returns: Number to be appended to either msec, sec or min when sending commands to the Rx

Definition at line 291 of file parsing_utilities.cpp.

◆ convertUTCDoubleToSeconds()

double parsing_utilities::convertUTCDoubleToSeconds ( double utc_double )

Converts UTC time from the without-colon-delimiter format to the number-of-seconds-since-midnight format.

Parameters

[in] utc_double Rrepresents UTC time in the without-colon-delimiter format

Returns: Represents UTC time in the number-of-seconds-since-midnight format

The UTC precision in NMEA messages is down to a tenth of a second, naturally in both the without-colon-delimiter and the number-of-seconds-since-midnight formats.

Definition at line 221 of file parsing_utilities.cpp.

◆ convertUTCtoUnix()

time_t parsing_utilities::convertUTCtoUnix ( double utc_double )

Converts UTC time from the without-colon-delimiter format to Unix Epoch time (a number-of-seconds-since-1970/01/01 format)

Note that the type "std::time_t" is usually 32 bits, which also leads to the "Year 2038 Problem".

Parameters

[in] utc_double Represents UTC time in the without-colon-delimiter format

Returns: The time_t variable representing Unix Epoch time

Time information (hours, minutes, seconds) is extracted from the given double and augmented with the date, which is taken from the current system time on the host computer (i.e. current UTC+some_shift time via time(0)). The date ambiguity is resolved by adding/subtracting a day to the current date if the host time is more than 12 hours behind/ahead the NMEA time (i.e. UTC time). Recall time(0), time(NULL): If argument is a null pointer, the parameter is not used (the function still returns the current calendar time of type time_t). Otherwise, the return value is the same as the one stored in the location pointed by the argument. Note that the function assumes that utc_double has two significant digits after the decimal point, i.e. hhmmss.ss, yet it does not round the number of seconds to the nearest unsigned integer, but instead disregards ss. This is since we use this function for the "header.stamp.sec" field of ROS messages, while "header.stamp.nsec" is taken care of separately.
