摘要

在本文中,我们扩展了先前针对GPS载波相位估计的交互多模型(IMM)卡尔曼滤波的研究。在准备工作中,我们开发了时钟的振动动力学模型和适用于干扰条件的载波噪声比估计器。我们将惯性测量单元(IMU)与GPS接收器耦合,为用户动态提供惯性辅助。

Inertial Aiding for Moving GPS Receiver Carrier Phase Estimation Through Wideband Interference
In this paper, we extend prior research on Interacting Multiple Model (IMM) Kalman filtering for GPS carrier phase estimation through wideband interference from static to moving receivers. In preparation, we develop a vibration dynamic model for the clock and a carrier-to-noise ratio estimator applicable in interference condition. We couple a Inertial Measurement Unit (IMU) with the GPS receiver to provide inertial aiding for user dynamics.
