Compared to the development of computers, or the Internet, or even cars, the evolution of aviation equipment appears to be very unhurried. Several factors contribute to this very gradual pace, but one of the most important is the extreme care with which any innovation affecting safety has to be examined, evaluated, analyzed, and tested. Satellite navigation equipment for aircraft is not an exception, so predicting its future for the next20 years is relatively easy compared to predictions for other fields. In this paper first of all we will describe briefly the challenges that satellite navigation must solve to be available solution for aviation. Then, we will describe the systems that have been developed to overcome these challenges and the performance they offer today, or will offer very soon. There is currently an explosion in satellite Navigation: before the end of this decade there will be over three times more satellites, offering civil signals in two distinct frequencies (as opposed to one today).

excellent research journals! - a must have these papers!!

翻译版的《MIMO无线网络手册》（第二版），15年11月才出的，费了很大功夫做了电子版，这里只有前四章，针对的是信道部分，讲的很全面细致，对研究这部分的人有很大帮助(Translated version of MIMO Wireless Network Handbook (second edition), November 15 was out, and spent a lot of effort to make the electronic version, there is only the first four chapters, is for part of the channel, said very detailed and thorough , the study of this part of the people are very helpful)

practical measurements with multimeter

he energy generated using a photovoltaic (PV) are depends mainly on meteorological factors such as temperature and solar radiation. Considering the high cost and the low efficiency of a PV system, it must operate at maximum power point (MPP) which changes with the load variations and weather conditions. This article presents the conception of a nonlinear controller for the DC-DC converter to retrieve a maximum power from photovoltaic systems (PV). This is affected via the control of duty cycle of the converter. The backstepping control is used to design the controller. The incremental conductance algorithm provides the output reference voltage PV to the backstepping controller. An integral Action is added in order to render the controller robust against changes of parameters and perturbations. The proposed controller performance is assessed by numerical simulations under changing atmospheric conditions(efficiency of a PV system, it must operate at maximum power point (MPP) which changes with the load variations and weather conditions.
