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).

第二部分，平时练习后保存的小程序，方便大家参考学习，适合初学者练习练习，增加代码量！(The second part, after the usual practice to save a small program to facilitate your learning, suitable for beginners to practice exercises to increase the amount of code!)

在STRUTS和SPRING整合框架下开发的一个商品管理模块，供学习框架的初学者参考(Integration of STRUTS and SPRING in the framework of the development of a product management module for beginners learning framework reference)

ctci是一本程序员面试的好书，不过其中内容大部分有java实现，这里提供了全部的c++代码，供C++程序员学习(ctci is a programmer interview books, but most of its contents have java to achieve, there is provided a full c++ code for programmers to learn C++)

说明：  SpringBoot 2.2.x 整合其他框架：MyBatis、Dubbo、Swagger2、SpringSecurity、RabbitMQ、RocketMQ、Kafka、Redis、MongoDB、Hazelcast、Apollo等(Springboot 2.2. X integrates other frameworks: mybatis, Dubbo, swagger2, spring security, rabbitmq, rocketmq, Kafka, redis, mongodb, hazelcast, Apollo, etc)

This code is Leap motion control sample. This code is a web app with java script.

STACK IN JAVA IS VERY UNDERSTANDABLE

说明：  Java推箱子游戏（一共有50关卡，带好听的音效），完整版源码，图形界面，看上去够专业。界面和泡泡堂游戏有点相似，学习游戏编程的JAVA朋友值得一看。 (Java Sokoban game (a total of 50 points, with good sound effects), the full version of source code, graphics interface, looks professional enough. Interface and the BNB to be somewhat similar game, learning game programming JAVA friends to see.)
