| 摘 要： | GPS罗盘是一种基于载波相位测姿原理的航向测量装置。对低成本GPS测姿定向设备的研制进行了尝试,介绍了一种基于OEM板开发的低成本GPS罗盘的设计和实现。GPS罗盘由2个GPSOEM板得到载波相位观测值,对其进行双差计算后,利用天线交换法消除整周模糊度解算出基线向量的方向,当基线向量沿载体纵轴时即得到载体的航向。通过GPS接收机的静态收星实验以及对设计出的GPS罗盘实验样机进行静态性能测试,试验结果表明该设计方案可行、有效。

| Abstract: | GPS compass is a heading indicator based on the theory of attitude determination using carrier phase measurement. This paper introduces the design and implementation of a low cost GPS compass based on GPS OEM board. GPS compass can determine the direction of the baseline vector by using the double difference of carrier phase measurement and resolving the integer ambiguity problem through the antenna-swapping method, thus the heading is acquired when the baseline vector is placed along the longitudinal axis.Static state experiments have been carried out to test the performance of a prototype, and the experiment results prove the feasibility and effectiveness of the proposed design. |
