Abstract

Optical Intersatellite links have been investigated for many years, but to date have enjoyed few spaceborne applications. The literature is rich in articles describing system issues such as jitter and pointing effects, but this author believes that simplifications generally made lead to significant errors. Simplifications made, for example, due to the complexity of joint distribution functions are easily overcome with widely available computer tools. Satellite- based data transport systems must offer similar Quality of Service (QoS) parameters as fiber-based transport. The movement to packet-based protocols adds additional constraints not often considered in past papers. BER may no longer be the dominant concern; packet loss, misdelivery, or severely corrupted packets can easily dominate the error budgets. The aggregation of static and dynamic pointing errors on both ends of such a link dramatically reduces the QoS. The approach described in this paper provides the terminal designer the methodology to analytically balance the impacts of these error sources against implementation solutions.
