中文说明： Precise Strapdow Inertial Navigation System (PSINS) toolbox for Matlab is an open source program package, primarily developed for inertial-grade or higher grade inertial navigation system simulation and data processing. PSINS toolbox includes strapdown inertial sensor (gyro & accelerometer) output simulation, initial self-alignment simulation, pure SINS navigation algorithm simulation, SINS/DR & SINS/GPS integrated navigation simulation and many other useful routes, all implemented by a bunch of powerful library functions. The PSINS library functions are well modularized and organized, then they are easy to understand and master. Surely, PSINS has the capability to processing real SIMU and GPS sampling data with a little or even no modification. On the basis of this PSINS toolbox, users can quickly and conveniently set up an inertial navigation solution to achieve their specific purpose
