4．Datasheets Datasheets are available for most ICs giving detailed information about their ratings and functions. In some cases example circuits are shown. The large amount of information with symbols and abbreviations can make datasheets seem overwhelming to a beginner, but they are worth reading as you become more confident because they contain a great deal of useful information for more experienced users designing and testing circuits.

If you need to remove a chip it can be gently prised out of the holder with a small flat- blade screwdriver. Carefully lever up each end by inserting the screwdriver blade between the chip and its holder and gently twisting the screwdriver. Take care to start lifting at both ends before you attempt to remove the chip, otherwise you will bend and possibly break the pins.

Lesson 17 Wireless Sensor Network
PART
A wireless sensor network (WSN) consists of spatially distributed autonomous sensors to monitor physical or environmental conditions, such as temperature, sound, pressure, etc. ,and to cooperatively pass their data through the network to a main location. The more modern networks are bi-directional, also enabling control of sensor activity. The development of wireless sensor networks was motivated by military applications such as battlefield surveillance; today such networks are used in many industrial and consumer applications, such as industrial process monitoring and control, machine health monitoring, and so on.

This modulated carrier is then transmitted to the required destination where it is received and the original information signal is obtained by demodulation. Sophisticated techniques have been developed for this process by using electromagnetic carrier waves operating at radio frequencies as well as microwave and millimeter wave frequencies. However, “communication” may also be achieved by using an electromagnetic carrier which is selected from the optical range of frequencies.

Lesson 16 Global Positioning System (GPS)
GPS is the Global Positioning System. GPS uses satellite technology to enable a terrestrial terminal to determine its position on the Earth in latitude and longitude.
Chinese Translation of Texts
GPS的工作使用三边测量法。三边测量是指在未知点两侧有两个或两个以上的 已知点，与未知点呈虚拟的三角形，通过测量未知点到已知点的边长来确定未知点。
Chinese Translation of Texts
In the GPS system, the two known points are provided by two GPS satellites. These satellites constantly transmit an identifying signal. The GPS receiver measures the distance to each GPS satellite by measuring the time each signal took to travel between the GPS satellite and the GPS receiver.

GPS operates using trilateration. Trilateration is the process of determining the position of an unknown point by measuring the lengths of the sides of an imaginary triangle between the unknown point and two or more known points.

第16课 全球定位系统（GPS）
GPS是全球卫星定位系统。GPS使用卫星技术，能使地面终端确定它在地球上 的经度和纬度的位置。
Chinese Translation of Texts
GPS receivers do this by measuring the signals from three or more satellites simultaneously and determining their position using the timing of these signals （Fig.16-1）.
Chinese Translation of Texts
GPS卫星的轨道离地区的距离约为20200公里。每个GPS卫星绕轨道一周的时 间为11小时58分钟。这意味着每一个GPS卫星每天绕地球两次。
Chinese Translation of Texts
These twenty-four satellites orbit in six orbital planes, or paths. This means that four GPS satellites operate in each orbital plane. Each of these six orbital planes is spaced sixty degrees apart. All of these orbital planes are inclined fiftyfive degrees from the Equator.
Chinese Translation of Texts
The receiver contains a mathematical model to account for these influences, and the satellites also broadcast some related information which helps the receiver in estimating the correct speed of propagation. Certain delay sources, such as the ionosphere, affect the speed of radio waves based on their frequencies, dual frequency receivers can actually measure the effects on the signals.
