GPS-Simulator
Der GPS-Simulator
Bei der Entwicklung meines AVR-UI-TNCs bzw. Trackers fьr APRS-Betrieb brauchte ich eine Quelle fьr GPS-Daten. Es war mir zu frьh, einen GPS-Empfдnger zu kaufen, also musste ich einen GPS-Simulator bauen. Davon gibt es schon mehrere im Internet (z.B. bei DJ7OO), aber mit anderen Controllern. Ich hatte Lust, so ein Ding selber zu bauen und zu programmieren, denn dann kann es genau das, was ich haben mцchte.
Mittlerweile habe ich eine GPS-Maus, deshalb konnte ich die alten, per Hand erzeugten Datenдtze des Simulators durch echte Datensдtze ersetzen.

GPS测量数据处理可分为基线解算和网平差两个阶段，基线解算就是利用ＧＰＳ接收机接收到的 载波相位观测值做为基本观测值，对其进行差分处理。(GPS data processing can be classified as the baseline solution and flat screen two phase difference, baseline solution is the use of GPS receivers to carrier phase observation value as the observation values. The of differential treatment.

Matlab_analyse_traffic_jam_status
根据深圳市出租车GPS数据所提供的信息，针对交通出行数据的空间分布特征，选取了4月18号这天的全天数据出租车载客后的行驶数据， 利用mtalab对数据的处理，筛选出出租车的起始点及拥堵的时段的行驶数据并通过kmeans聚类分析设定拥堵的标准，得到对于出租车在路段上的车速在小于2.15公里/小时的时候可以认为非常拥堵，拥堵的时段 5:00-7:00,12:00-14:00,19:00-21:00，非常拥堵的时间段为5:00-7:00，19:00-21:00。(analyse traffic jam status of the shenzhen city)

GPS-postion-Nav-source
gps定位程序 测试通过，可以直接拿来用 GPS卫星提供了P码（精码）和C/A码（粗码）两种定位服务。P码为军方服务，定位精度达到3米；C/A码对社会开放，定位精度为14米。出于自身安全的考虑，美国先后实施了SA和AS政策。SA政策在C/A码中人为引入了误差，使定位精度下降到100米；AS政策则对P码实行加密。 由于GPS对社会开放，因此各类接收机、测量设备如雨后春笋般涌现，并广泛应用于各行各业，彻底改变了传统的定位导航方式.(gps positioning program testing by direct use of them GPS satellites provide two kinds of location-based services in the P-code (precise code) and the C/A code (coarse code). P code for military service, positioning accuracy of 3 meters C/A code of the open society, positioning accuracy of 14 meters. For their own security reasons, the United States has implemented a policy of SA and AS. SA policy is artificially introduced in the C/A code of the error, so that the positioning accuracy down to 100 meters AS policy is implemented in P-code encryption. GPS open society, the various types of receivers, measuring equipment have sprung up, and are widely used in all walks of life, completely changed the traditional positioning and navigation.)
