【摘要】 介绍一种新的PPK信号磁带记录技术,其新颖点在于实现了PPK信号和同步解调时钟在同一磁道上记录,彻底消除磁带扭斜对PPK信号磁带计测精度的影响,并且在磁带抖动影响下获得4‰的精度更多还原

【Abstract】 A kind of new technology of magnetic tape record for PPK singal are discussed in this paper.The novelty of this new technology is that PPK signal and synchro demodulating clock are recorded on the same magnetic track,thus the influence on the precision of PPK signal instrumentaiton by the magnetic tape skew are eliminated at all and the attainable precision is 4‰ under the influence of the magnetic tape flutter.更多还原
