Description: magnetic field strength, making this approach unsuitable for
deep space missions, and also more suitable for low Earth orbits
as opposed to higher ones like the geosynchronous. The
dependence on the highly variable intensity of Earth’s magnetic
field is also problematic because the attitude control
problem becomes highly nonlinear. It is also impossible to control
attitude in all three axes even if the full three coils are used,
since the torque can be generated only perpendicular to the
Earth’s magnetic field vector (Samir, 2009 Vincent, 2010).
Recently, the possibility of using laser power for space
applications becomes of great interest. There are several
advantages of lasers over other techniques of beamed power
the laser receiver is the solar array, so no new receiver technology
is needed. Moreover, space laser beam suffers a less
amount of atmospheric attenuation also it is safe in use where
it cannot produce damage in the satellite surface (El-saftawy-magnetic field strength, making this approach unsuitable for

Description: 国外开发的GPS实用工具，值得借鉴！
这是一套三的程序，可以读取GPS NMEA位置数据，以及做各种各样的事情，如下：
-将作为一个GPS接收器simulate.exe位置并输出数据到串行端口。你可以选择一个位置/速度/方向或者你可以重放记录的位置数据。我用这个广泛的其他程序来读取GPS位置数据在发展。你可以使用两个物理串行端口和一个零调制解调器电缆，或虚拟串口与零调制解调器的配置。
com0com虚拟串口零调制解调器软件。
capture.exe NMEA数据记录-将在稍后的时间分析或处理一个文件。也可以去一些指定的时间长度，或登录不断。
- process.exe会读NMEA日志文件和计算的统计数据。这是主要用于静态精度检验，但可用于快速在一些操作看卫星可见性。由此产生的数据保存为图像，并有一个htm文件来显示它们。-This is a suite of three programs that are designed to do various things with GPS NMEA position data.
- Simulate.exe will act as a GPS receiver and output position data to a serial port. You can a location/speed/direction or you can have it replay some recorded position data. I use this extensively during the development of other programs that are designed to read GPS position data. You can use two physical serial ports and a null modem cable, or virtual serial ports with a null modem configuration.
com0com Virtual serial port null modem software.
- Capture.exe will record NMEA data to a file for analysis or processing at a later time. It can go for some specified length of time, or log continually.
- Process.exe will read a NMEA log file and calculate statistical data on it. This is used primarily for static accuracy testing, but could be used to quickly see satellite visibility during some operation. The resulting data is saved as images, and there is a .htm file to display Platform: |
