Neville插值CUMT
说明： 输入一天内的小时和分钟以及阶数，自动读取精密星历文件，Neville插值在所给阶数数据中间精度最高，所以会自动选择精度最高的情况插值。替换目录下sp3文件即可完成修改。(Input the hour, minute and order of a day, and automatically read the precise ephemeris file. Neville interpolation has the highest accuracy among the given order data, so it will automatically select the case with the highest accuracy. Replace the SP3 file in the directory to complete the modification.)

Heterogeneous-network
无线通信网络的发展趋势之一是将各种不同无线接入技术进行融合。多接入选择作为无线资源管理中的关键技术是目前异构网融合的研究热点之一。从用户的利益出发，充分考虑预接入网络的费用、QoS 和稳定性；假定不同的网络运营商之间是彼此竞争的，即没有达成统一的协议，提出了一种结合目标代价函数与层次分析法的动态多接入选择算法。通过对影响因素进行分析和二次判断，建立了网络选择决策模型，仿真结果验证了该算法的正确性与有效性。(Trends in wireless communication network is one of a variety of different wireless access technologies will be integrated. Multi-access radio resource management in selection as the key technology is the integration of heterogeneous networks of research focus. From the user' s interests fully into account the cost of pre-access networks, QoS and stability assumed between different network operators are competing with each other, that did not reach uniform agreement, proposed a combination of objective cost function and level analysis of dynamic multi-access selection algorithm. Through analysis of the factors affecting the judge and the second, the establishment of a network selection decision-making model, simulation results verify the correctness and validity of the algorithm.)

GNSS
单点定位就是根据一台接收机的观测数据来确定接收机位置的方式，它只能采用伪距观测量，可用于车船等的概略导航定位。(Single point positioning is based on observations of a receiver to determine the position of the receiver way, it only can use the false distance measurements, can be used to approximate the travel and other navigation and positioning)
