Abstract

Currently, high-precision GNSS receivers are expensive and the cost of using them in mobile communication networks is extremely high. To reduce the construction cost of positioning and timing capabilities in mobile communication networks, the existing ordinary GNSS receivers in the network are used to form a self-differential enhanced iterative network to achieve high-precision positioning in local areas.Based on high-precision positioning, various delay errors in the current 1PPS second pulse are corrected by differential information data to solve the precise time of the local clock, thereby improving timing accuracy. In engineering applications, the self-differential enhanced iterative network algorithm is used to make embedded improvements to the antenna parameter sensor commonly used in mobile communication networks. The improved antenna parameter sensor has obtained high-precision positioning and timing functions based on the original attitude and direction measurement functions. Its positioning accuracy can reach millimeter level, and the timing accuracy can reach 20 nanoseconds.

移动通信网络GNSS接收机高精度定位授时方法

目前，高精度GNSS接收机价格昂贵，在移动通信网络中使用成本极高。为了降低移动通信网络中定位授时能力的建设成本，利用网络中已有的普通GNSS接收机组成自微分增强迭代网络，实现局部高精度定位。在高精度定位的基础上，利用差分信息数据对当前1PPS秒脉冲中的各种延迟误差进行校正，求解本地时钟的精确时间，从而提高授时精度。在工程应用中，采用自微分增强迭代网络算法对移动通信网络中常用的天线参数传感器进行嵌入式改进。改进后的天线参数传感器在原有姿态和方向测量功能的基础上获得了高精度的定位和授时功能。其定位精度可达毫米级，授时精度可达20纳秒。

期刊介绍： Microprocessors and Microsystems: Embedded Hardware Design (MICPRO) is a journal covering all design and architectural aspects related to embedded systems hardware. This includes different embedded system hardware platforms ranging from custom hardware via reconfigurable systems and application specific processors to general purpose embedded processors. Special emphasis is put on novel complex embedded architectures, such as systems on chip (SoC), systems on a programmable/reconfigurable chip (SoPC) and multi-processor systems on a chip (MPSoC), as well as, their memory and communication methods and structures, such as network-on-chip (NoC). Design automation of such systems including methodologies, techniques, flows and tools for their design, as well as, novel designs of hardware components fall within the scope of this journal. Novel cyber-physical applications that use embedded systems are also central in this journal. While software is not in the main focus of this journal, methods of hardware/software co-design, as well as, application restructuring and mapping to embedded hardware platforms, that consider interplay between software and hardware components with emphasis on hardware, are also in the journal scope.
