# D.4 Default Priorities of Multiple Signals/多个信号默认优先级    #

如果输入观测数据中，一个频率中包含多个信号，RTKLIB将按照以下默认优先级选择一个信号进行处理。 要选择合适的信号，请使用RINEX选项或附录D.5中所述的与接收器相关的选项。在用户AP中，要更改或获取信号优先级，请使用API setcodepri()或getcodepri()

## 1、设置信号优先级： ##

/* set code priority设置代码优先级 -----------------------------------------------------------
    * set code priority for multiple codes in a frequency
    * args   : int    sys     I     system (or of SYS_???)
    *          int    freq    I     frequency (1:L1,2:L2,3:L5,4:L6,5:L7,6:L8,7:L9)
    *          char   *pri    I     priority of codes (series of code characters)
    *                               (higher priority precedes lower)
    * return : none
    *-----------------------------------------------------------------------------*/
    extern void setcodepri(int sys, int freq, const char *pri)
    {
        trace(3,"setcodepri:sys=%d freq=%d pri=%s\n",sys,freq,pri);
        
        if (freq<=0||MAXFREQ<freq) return;
        if (sys&SYS_GPS) strcpy(codepris[0][freq-1],pri);
        if (sys&SYS_GLO) strcpy(codepris[1][freq-1],pri);
        if (sys&SYS_GAL) strcpy(codepris[2][freq-1],pri);
        if (sys&SYS_QZS) strcpy(codepris[3][freq-1],pri);
        if (sys&SYS_SBS) strcpy(codepris[4][freq-1],pri);

        if (sys&SYS_IRN) strcpy(codepris[6][freq-1],pri);
    }

## 2、获取信号优先级/一个频率内多个信号的优先级 ##

/* get code priority 获取代码优先级-----------------------------------------------------------
    * get code priority for multiple codes in a frequency
    * args   : int    sys     I     system (SYS_???)

    *          char   *opt    I     code options (NULL:no option)
    * return : priority (15:highest-1:lowest,0:error)
    *-----------------------------------------------------------------------------*/
    extern int getcodepri(int sys, unsigned char code, const char *opt)
    {
        const char *p,*optstr;
        char *obs,str[8]="";
        int i,j;
        
        switch (sys) {

            case SYS_CMP: i=5; optstr="-CL%2s"; break;
            case SYS_IRN: i=6; optstr="-IL%2s"; break;
            default: return 0;
        }
        obs=code2obs(code,&j);
        
        /* parse code options */
        for (p=opt;p&&(p=strchr(p,'-'));p++) {
            if (sscanf(p,optstr,str)<1||str[0]!=obs[0]) continue;
            return str[1]==obs[1]?15:0;
        }
        /* search code priority */
        return (p=strchr(codepris[i][j-1],obs[1]))?14-(int)(p-codepris[i][j-1]):0;
    }
