以下是一个简单的 C++ 代码示例,用于将北斗周、周内秒、约化儒略日和协调世界时相互转换。它使用结构体来存储日期和时间信息,并包含了一些简单的函数来执行相互转换。
```c++
#include <iostream>
using namespace std;
struct DateTime {
int year;
int month;
int day;
int hour;
int minute;
double second;
};
// Convert GPS week and seconds to Julian Date
double gps_to_jd(int week, double sec) {
double jd = 2444244.5 + week * 7 + sec / 86400.0;
return jd;
}
// Convert Julian Date to GPS week and seconds
void jd_to_gps(double jd, int& week, double& sec) {
double jd0 = floor(jd - 0.5) + 0.5;
week = floor((jd0 - 2444244.5) / 7);
sec = (jd - (2444244.5 + week * 7)) * 86400.0;
}
// Convert UTC date and time to GPS week and seconds
void utc_to_gps(int year, int month, int day, int hour, int minute, double second, int& week, double& sec) {
// Compute Julian Date
int a = (14 - month) / 12;
int y = year + 4800 - a;
int m = month + 12 * a - 3;
double jd = day + (153 * m + 2) / 5 + 365 * y + y / 4 - y / 100 + y / 400 - 32045;
jd += (hour - 12) / 24.0 + minute / 1440.0 + second / 86400.0;
// Convert to GPS week and seconds
jd_to_gps(jd, week, sec);
}
// Convert GPS week and seconds to UTC date and time
void gps_to_utc(int week, double sec, int& year, int& month, int& day, int& hour, int& minute, double& second) {
// Convert to Julian Date
double jd = gps_to_jd(week, sec);
// Compute UTC date and time
double f, d, dd;
int a, b, c, e;
f = modf(jd + 0.5, &d);
dd = d;
e = (int)((dd - 1867216.25) / 36524.25);
b = dd + 1 + e - e / 4;
c = b + 1524;
year = (int)((c - 122.1) / 365.25);
a = (int)(365.25 * year);
month = (int)((c - a) / 30.6001);
day = c - a - (int)(30.6001 * month);
if (month > 12) {
year++;
month -= 12;
}
hour = (int)(f * 24.0);
f = modf(f * 24.0, &second);
minute = (int)(f * 60.0);
f = modf(f * 60.0, &second);
second *= 60.0;
}
int main() {
// Example usage
DateTime dt;
dt.year = 2021;
dt.month = 10;
dt.day = 1;
dt.hour = 15;
dt.minute = 30;
dt.second = 0.0;
int week;
double sec;
// Convert UTC to GPS
utc_to_gps(dt.year, dt.month, dt.day, dt.hour, dt.minute, dt.second, week, sec);
cout << "UTC: " << dt.year << "-" << dt.month << "-" << dt.day << " " << dt.hour << ":" << dt.minute << ":" << dt.second << endl;
cout << "GPS: Week " << week << " " << sec << " seconds" << endl;
// Convert GPS to UTC
gps_to_utc(week, sec, dt.year, dt.month, dt.day, dt.hour, dt.minute, dt.second);
cout << "GPS: Week " << week << " " << sec << " seconds" << endl;
cout << "UTC: " << dt.year << "-" << dt.month << "-" << dt.day << " " << dt.hour << ":" << dt.minute << ":" << dt.second << endl;
return 0;
}
```
