Description: ALM2POS computation for satellite position from almanac data file
[pos,R]=alm2pos(almanac,PRN,time) calculates the satellite position in the
Terrestial and in the Celestial reference frame for a desiderate satellite
vehicle (PRN) with almanac data (ALMANAC). The given time (TIME) can be a
scalar or also a vector. Colomn 1-3 of position (pos) are Terrestial
Coordinates (ECEF) colomn 4-6 of position are Celestial Coordinates (ECSF)
in m. Another output is the position vector of the satellite (R) in m.- ALM2POS computation for satellite position from almanac data file

These scripts were developed for/during a class in GPS and Active Tectonics
Department of Geology and Geophysics, U. Utah, Spring, 1994
EXAMPLE RINEX Files (the only ones guaranteed to work this release)
CUR10911.94N
CUR10911.94O
PAR10910.94N
PAR10910.94O
Main Program scripts:
gpshora.m -- function to calculate Modified Julian Day, Homework#1
HW2.m -- Homework#2 read RINEX observation file and plot C/A code vrs. time
HW3_plt.m-- Homework#3 read RINEX navigation file, plot satellite positions
HW3_3dplt.m-- Same as HW3_plt.m, but 3d position plots
HW4.m-- Homework#4 calculate and plot station position as function of time
Functions called:
calc_nav.m-- calculate satellite position
calc_pos1.m-- calculate station position
constants.m-- GPS constants
coords.m-- convert x,y,z coordinates to lat, long, height

Description: GPS(Golbal Position System)全球定位系统是一个在做一些项目中很常用到的仪器，它通过卫星的通信可以返回给你你当前所处的时间，时区，经纬度等等。VC++编写GPS通信是属于典型的基本的串口通信例子，而且只用接收信息即可，不用对GPS发送信息。
编写通信的方法的前半部分都跟我上篇文章说的串口通信一样，即注册ActiveX，建立实例及事件的映射等等。完成上面的操作后，你就可以接收的GPS发来的信息了。-GPS (Golbal Position System) GPS is a very commonly used to do some projects to the instrument, it can be returned via satellite communications to you in which your current time, time zone, latitude and longitude, and so on. GPS VC++ written communication is a typical example of the basic serial communication example, and can only receive information, do not send the GPS information. Written communication methods related to the first half of the last article I said the same serial communication, that is registered ActiveX, create an instance and event mapping, and so on. After completion of the above operation, you can receive the GPS sent information. Platform: |
