输入卫星星号和周内秒实现卫星位置计算c++代码，分.h.cpp

以下是一个简单的卫星位置计算的C++代码，分为.h和.cpp两个文件：

satellite.h：

#ifndef SATELLITE_H
#define SATELLITE_H

class Satellite {
public:
    Satellite(double t, double a, double e, double i, double Omega, double omega, double M);

    void setT(double t);
    void setA(double a);
    void setE(double e);
    void setI(double i);
    void setOmega(double Omega);
    void setOmega(double omega);
    void setM(double M);

    double getX();
    double getY();
    double getZ();

private:
    double t_; // 周内秒
    double a_; // 卫星轨道长半轴
    double e_; // 卫星轨道偏心率
    double i_; // 卫星轨道倾角
    double Omega_; // 升交点赤经
    double omega_; // 近地点幅角
    double M_; // 平近点角
};

#endif // SATELLITE_H

satellite.cpp：

#include "satellite.h"
#include <cmath>

#define PI 3.14159265358979323846
#define GM 3.986004418e14

Satellite::Satellite(double t, double a, double e, double i, double Omega, double omega, double M)
    : t_(t), a_(a), e_(e), i_(i), Omega_(Omega), omega_(omega), M_(M)
{}

void Satellite::setT(double t) {
    t_ = t;
}

void Satellite::setA(double a) {
    a_ = a;
}

void Satellite::setE(double e) {
    e_ = e;
}

void Satellite::setI(double i) {
    i_ = i;
}

void Satellite::setOmega(double Omega) {
    Omega_ = Omega;
}

void Satellite::setOmega(double omega) {
    omega_ = omega;
}

void Satellite::setM(double M) {
    M_ = M;
}

double Satellite::getX() {
    double E = M_;
    double deltaE = 1.0;
    double epsilon = 1e-12;
    while (deltaE > epsilon) {
        double E0 = E;
        E = M_ + e_ * sin(E0);
        deltaE = fabs(E - E0);
    }

    double v = atan2(sqrt(1 - e_ * e_) * sin(E), cos(E) - e_);

    double r = a_ * (1 - e_ * cos(E));
    double x = r * (cos(Omega_) * cos(omega_ + v) - sin(Omega_) * sin(omega_ + v) * cos(i_));
    return x;
}

double Satellite::getY() {
    double E = M_;
    double deltaE = 1.0;
    double epsilon = 1e-12;
    while (deltaE > epsilon) {
        double E0 = E;
        E = M_ + e_ * sin(E0);
        deltaE = fabs(E - E0);
    }

    double v = atan2(sqrt(1 - e_ * e_) * sin(E), cos(E) - e_);

    double r = a_ * (1 - e_ * cos(E));
    double y = r * (sin(Omega_) * cos(omega_ + v) + cos(Omega_) * sin(omega_ + v) * cos(i_));
    return y;
}

double Satellite::getZ() {
    double E = M_;
    double deltaE = 1.0;
    double epsilon = 1e-12;
    while (deltaE > epsilon) {
        double E0 = E;
        E = M_ + e_ * sin(E0);
        deltaE = fabs(E - E0);
    }

    double v = atan2(sqrt(1 - e_ * e_) * sin(E), cos(E) - e_);

    double r = a_ * (1 - e_ * cos(E));
    double z = r * sin(omega_ + v) * sin(i_);
    return z;
}

使用方法：

1. 在你的项目中包含satellite.h和satellite.cpp文件
2. 创建一个卫星对象，传入卫星的初始参数
3. 调用getX(), getY()和getZ()方法即可得到卫星的位置坐标

示例代码：

#include "satellite.h"
#include <iostream>

int main() {
    double t = 86400; // 周内秒
    double a = 42164160; // 卫星轨道长半轴
    double e = 0.0001; // 卫星轨道偏心率
    double i = 0.5; // 卫星轨道倾角
    double Omega = 1.2; // 升交点赤经
    double omega = 0.8; // 近地点幅角
    double M = 1.5; // 平近点角

    Satellite satellite(t, a, e, i, Omega, omega, M);

    std::cout << "x: " << satellite.getX() << std::endl;
    std::cout << "y: " << satellite.getY() << std::endl;
    std::cout << "z: " << satellite.getZ() << std::endl;

    return 0;
}
