Description: matlab读取GPS时间信息，UTC代码- GPS2UTC Convert GPS time tags to UTC(GMT) time accounting for leap seconds
GPS2UTC(date) corrects an array of GPS dates(in any matlab format) for
leap seconds and returns an array of UTC datenums where:
UTC = GPS- steptime
Currently step times are through Jan 1 2009, but need to be added below
as they are instuted. All input dates must be later than the start of
GPS time on Jan 6 1980 00:00:00

Description: 很好的GPS/INS超紧组合导航的文章，关键词：GPS,INS，超紧组合导航，抗干扰-The performance of an Ultra-Tightly Coupled
(UTC) Global Positioning System/Inertial Navigation System
(GPS/INS) is evaluated using a system simulation of the GPS
receiver and navigation processing. The UTC system being
analyzed uses a bank of pre-filters to estimate code delay error
and Doppler frequency error for each satellite. These outputs are
sent to a central Kalman navigation filter. This central processor
generates estimates of inertial navigation position, velocity, and
attitude errors IMU biases and user clock errors, which are
used to correct the navigation solution. In the UTC approach,
outputs from the central navigation processor, after projection
into satellite line-of-sight coordinates, are used to control the
code and carrier replica signals for each satellite channel. In
contrast, a conventional tightly coupled GPS/INS system uses
separate tracking loops for each satellite channel, which operate
autonomously. As a result, the UTC desig

Description: 本实验将实现如下功能：通过串口2连接ATK-NEO-6M GPS模块，然后通过液晶显示GPS信息，包括精度、纬度、高度、速度、用于定位的卫星数、可见卫星数、UTC时间等信息。同时，可以通过USMART工具，设置GPS模块的刷新速率（最大支持5Hz刷新）和时钟脉冲的配置。另外，通过KEY0按键，可以开启或关闭NMEA数据的上传（即输出到串口1，方便开发调试）。-The experiment will achieve the following functions: connection through the serial port 2 ATK-NEO-6M GPS module and GPS information through the LCD display, including accuracy, latitude, altitude, speed, number of satellites used for positioning, the number of visible satellites, UTC time information . Meanwhile, you can USMART tool, set the refresh rate GPS module (maximum support 5Hz refresh) configuration and clock pulse. In addition, through KEY0 button, you can turn on or off to upload NMEA data (ie the output to the serial port 1, to facilitate development and debugging).

Description: T_XTIDE Tidal prediction
YOUT=T_XTIDE(STATION) makes a tidal prediction
for the current day using the harmonics file XTIDE. Predictions
at other times can be generated using [...]=T_XTIDE(STATION,TIM)
where TIM is a vector of matlab-format decimal days ( DATENUM).
If TIM is a scalar then it is taken as the number of days present
over which to make predictions. If TIM>1000 then it is taken to be
the starting time in matlab-format.
at the matlab time JD (UTC, but see code for details) where
tau = lunar time
s = mean longitude of the moon
h = mean longitude of the sun
p = mean longitude of the lunar perigee
np = negative of the longitude of the mean ascending node
pp = mean longitude of the perihelion (solar perigee)
