STK
针对STK(Satellite Tool Kit)软件在军事任务可视化仿真领域中的广泛应用,为充分挖掘
其显示潜能,重点解决了影响其三维场景构建的瓶颈问题,即三维场景数据格式的转换和数据的获取
优化。在分析构建STK 三维场景所需要素及其作用的基础上,分别对地形、地表纹理、三维模型和GIS
等四类数据格式进行分析,并利用多种辅助软件,系统地提出了由较通用格式数据向STK 所支持格式
数据的转换方法,以及在对各类原始数据的获取和转换过程中出现的问题进行处理的优化方法。最后通过实例验证表明该数据格式转换方法和数据优化方法行之有效,三维场景显示效果逼真。(STK (Satellite Tool Kit) software widely used in the field of military tasks, visual simulation, to fully tap its display potential, focus on resolving the bottlenecks that affect the construction of the three-dimensional scene, 3D scene data format conversion and data Get optimization. On the basis of the required elements and their role in the analysis of building STK three-dimensional scene analysis, respectively, of the four types of terrain, surface texture, three-dimensional model and GIS data format and use a variety of assistive software, the system proposed by the more common format The data support the format of the data to STK conversion method, as well as access to various types of raw data and conversion process issues deal with the optimization method. Finally, an example to show that the data format conversion method and data optimization method is effective, realistic three-dimensional scene display.)

rtklib_2.4.1
rtklib 版本2.4.1
An Open Source Program Package for GNSS Positioning
日本开源网站上提供的关于GPS卫星数据解算的程序。All of the executable binary APs for Windows are included in the package as well as whole source programs of the library and the APs.
* For real-time PPP, EUREF and IGS have already started to distribute real-time satellite orbit and clock as RTCM v.3 SSR messages via NTRIP. To receive the real-time satellite orbit and clock, users have to make registration and get an account to access the NTRIP broadcasters. Refer BKG GDC site http://igs.bkg.bund.de/ntrip/index for details.
(All of the library functions and APIs are written in ANSI C (C89). The library internally uses standard socket and pthread for Linux/UNIX or winsock and WIN32 thread for Windows. By setting compiler option-DLAPACK or-DMKL, the library uses LAPACK/BLAS or Intel MKL for fast matrix computation. The console APs are also written in standard C. The library and console APs can be built on many environments like gcc on Linux. The GUI APs are written in C++ and utilize Borland VCL for the GUI toolkit. All of the executable binary APs in the package were built by free edition Borland Turbo C++ 2006 (http://www.turboexplorer.com)* on Windows. The binary APs were tested on Windows XP SP3 32bit and Windows 7 SP1 64bit. The console APs are also built and tested on Ubuntu 9.04 Linux.

说明: 超紧耦合是 GPS/INS 组合导航系统的最新研究方向,它采用 INS 测得的载体动态信息辅助 GPS 接收机跟踪环
路,消除卫星信号中由于载体与卫星之间相对运动所产生的频率偏移,提高接收机在高动态环境下载波跟踪性能,同时还
可以压缩带宽,有效增强接收机抗干扰性能。介绍 GPS/INS 超紧耦合技术,给出 INS 辅助 GPS 载波跟踪环路结构图和相应
的数学模型,分析 INS 辅助 GPS 跟踪环路在动态环境下的动态残留及其对环路相位误差的影响,并进行了模型仿真,最后
对仿真结果进行了验证分析。仿真结果显示,辅助动态残留及其导致的环路相位误差的大小与加加速度、环路辅助时间间
隔成正比。
(The ultra-tightly coupled GPS/INS integrated navigation system latest research direction, it adopted the INS measured the carrier dynamic information auxiliary GPS receiver tracking loop to eliminate the satellite signal frequency due to the relative motion between the carrier and the satellite offset improve the receiver in high dynamic environment download wave tracking performance, but also can compress bandwidth, effectively enhance the anti-jamming performance of the receiver. Introduced GPS/INS ultra-tight coupling technology gives INS assisted GPS carrier tracking loop diagram and the corresponding mathematical model to analyze the impact of the INS assisted GPS tracking loop dynamic residues in a dynamic environment and the loop phase error, and model simulation, and analysis of simulation results verified. Simulation results show that the the residual secondary dynamic its resulting size of the error loop phase and jerk loop secondary is proportional to the time interval.)
