Inter-satellite range-finding method with high precision and large range based on optoelectronic resonance

【摘要】 As microsatellite technology develops,precise inter-satellite measurement shows its significance in distributed satellite systems.In this Letter,a novel technique is proposed for measuring the inter-satellite distance,which adopts optoelectronic resonance and has a function of self-referencing.Resonance cavities have a high spectral purity and a high oscillation frequency.By utilizing the accumulative amplification principle to convert the measurement of distance to that of the frequency,high accuracy is achieved.In the experiment,this measuring scheme has a large measuring range between 1 and 6 km(can be potentially larger),and the accuracy is better than 1.5 urn.The relative accuracy reaches the level of 10-10.更多还原
