This paper deals with using of low-cost Global Navigation Satellite System (GNSS) sensors in a localization process for an autonomous guidance system of mobile robots. Generally, this process is made using a Kalman Filter (KF) to fuse informa

The Monte Carlo Investigation of Trajectory Operations and Requirements (MONITOR) program was developed to perform spacecraft mission maneuver simulations for geosynchronous, single maneuver, and comet encounter type trajectories. MONITOR is a multif

3GPP组织发布的卫星移动通信标准还停留在3G阶段。对卫星LTE系列标准的研究，如通信协议和流程，常使用网络仿真方式。对EPS系统、开源网络仿真工具NS一3中的LTE仿真模型LENA给出了简要介绍，重点讨论了LENA模型与真实LTE系统的差异，并针对卫星移动通信环境存在大时延、高误码、信道衰落有别于地面等特点，分析和总结了利用LENA模型进行星上LTE系统仿真需要完善之处，为研究和制定卫星I肛移动通信系统标准打下了基础。(The standard of satellite mobile comm
