说明：convert from earth fixed earth centered coordinate system to orbital frame (of a satellite) coordinate system.

说明：姿态解算的好程序，希望大家共同分享。共同进步啊

说明：Software-defined radios (SDRs) have been around for more than a decade. The first complete Global Positioning System (GPS) implementation was described by Dennis Akos in 1997. Since then several research groups have presented their contributions.We therefore find it timely to publish an up-to-date text on the subject and at the same time include Galileo, the forthcoming European satellitebased navigation system. Both GPS and Galileo belong to the category of Global Navigation Satellite Systems (GNSS)

说明：卫星光通信技术及其在载人航天工程中的应用，主要描述了卫星光通讯的实际应用

说明：就通信系统而言，涉及到有线信道及非卫星无线信道的问题时，信道不再可以看成为恒参信道，信号往往是通过未知信道传播，通常把这样的信道称为盲信道。 本源代码对盲信道的参数进行估计，利用matlab仿真，对做盲信道的工程人员有一定的借鉴价值。

说明：Sky lab calculate position of satellite in GNSS systems and calculate elevation and azimuth them and show them.

说明：In the planning stage of a GNSS-measurement campaign it is useful to compute several design para-meters in order to decide how, when and where to carry out the measurements. The MATLAB user interface VISUAL.M enables you to compute the design parameters for any system design.

说明：This source code for calculate of element of satellite.

说明：Spacecraft Attitude Determination Using Global Positioning Satellite Signals - Johnson

说明：To identify distinguishable clusters of data in an n-dimensional pixel value image. Given: Samples of multi-spectral satellite images

说明：satellite attitude determination

说明：With the Wireless module, OPNET can model both terrestrial and satellite radio systems. In this tutorial, you will use Modeler and Wireless modeling to create a radio network you will also observe variations in the quality of received signal that results from radio noise at the receiving node in a dynamic network topology.

说明：基于MATLAB的GPS选星分析及实验研究
