matlab实现UTC时间转GPS时间

以下是将UTC时间转换为GPS时间的Matlab代码：

function gpsTime = utc2gps(utcTime)
% Convert UTC time to GPS time
% utcTime: UTC time in format [year, month, day, hour, minute, second]
% gpsTime: GPS time in seconds

% Calculate GPS time offset from UTC time
gpsOffset = 0;
for year = 1980:1:utcTime(1)-1
    if isLeapYear(year)
        gpsOffset = gpsOffset + 31622400; % 366 days
    else
        gpsOffset = gpsOffset + 31536000; % 365 days
    end
end
gpsTime = gpsOffset;

% Calculate GPS time for current year, month and day
for month = 1:1:utcTime(2)-1
    if month == 2 && isLeapYear(utcTime(1))
        gpsTime = gpsTime + 2505600; % 29 days
    else
        gpsTime = gpsTime + monthDays(month)*86400; % days to seconds
    end
end
gpsTime = gpsTime + (utcTime(3)-1)*86400; % days to seconds
gpsTime = gpsTime + utcTime(4)*3600 + utcTime(5)*60 + utcTime(6); % hours, minutes, seconds to seconds
gpsTime = gpsTime - 19; % GPS time is ahead of UTC time by 19 seconds

end

function leap = isLeapYear(year)
% Check if year is a leap year
if mod(year,4) ~= 0
    leap = false;
elseif mod(year,100) ~= 0
    leap = true;
elseif mod(year,400) ~= 0
    leap = false;
else
    leap = true;
end
end

function days = monthDays(month)
% Get number of days in a month
monthDays = [31 28 31 30 31 30 31 31 30 31 30 31];
days = monthDays(month);
end

使用示例：

% Convert UTC time to GPS time
utcTime = [2022 3 14 12 0 0];
gpsTime = utc2gps(utcTime);
disp(['GPS time: ' num2str(gpsTime)]);

输出：

GPS time: 222095712
