“…One of the simplest ways to do open-loop synchronization is through Master-slaves architectures, where one primary node broadcasts a beacon, and the secondary nodes lock their oscillators to this reference [6]. This algorithm can be considered as a closed-loop method if the primary node is not part of the DSS [70].…”

“…Generally, closed-loop synchronization methods are not the ideal solution for space-ground or long distances communication links due to the intrinsic delay between the DSS and the target nodes. In addition, other constraints such as the slow convergence of the iterative bit feedback algorithms [64]; the high power consumption and scalability problems of T-RT [76] and; the self-interference problem of F-RT algorithm [6] makes them not suitable for synchronization in CDSS. Maybe the most promising solution among the closed-loop methods for CDSS could be the consensus synchronization algorithm proposed in [78].…”

CDSS is a key enabling technology for the future of remote sensing and communication missions. However, they have to meet strict synchronization requirements before their use is generalized. When clock or local oscillator signals are generated locally at each of the distributed nodes, achieving exact synchronization in absolute phase, frequency, and time is a complex problem. In addition, satellite systems have significant resource constraints, especially for small satellites, which are envisioned to be part of the future CDSS. Thus, the development of precise, robust, and resource-efficient synchronization techniques is essential for the advancement of future CDSS. In this context, this survey aims to summarize and categorize the most relevant results on synchronization techniques for DSS. First, some important architecture and system concepts are defined. Then, the synchronization methods reported in the literature are reviewed and categorized. This article also provides an extensive list of applications and examples of synchronization techniques for DSS in addition to the most significant advances in other operations closely related to synchronization, such as inter-satellite ranging and relative position. The survey also provides a discussion on emerging data-driven synchronization techniques based on ML. Finally, a compilation of current research activities and potential research topics is proposed, identifying problems and open challenges that can be useful for researchers in the field.

“…In this case, the final resolution depends on the accuracy of the phase synchronization achieved between the satellites [5]. For some applications, the synchronization requirement is the critical limiting factor in making practical implementations possible [6]. In those cases, the level of effort, power consumption, and complexity required for the synchronization algorithm may be higher than those needed for the mission itself.…”

“…The work is restricted to the implementation of two remote phase synchronization nodes in a Cubesat-ready Software Defined Radio (SDR) payload for feasibility study and demonstration purposes. The algorithm has been already described and tested with ground equipment in [3], [4]. It is assumed that the nodes to be synchronized are either orbiting, flying or hovering, and they are part of a distributed system performing a cooperative coherent operation.…”

Distributed antenna arrays, fractionated payloads and cooperative platforms can provide unprecedented performance in the next generation of spaceborne communications and remote sensing systems. Remote phase synchronization of physically separated oscillators is the first step towards a coherent operation of distributed systems. This work shows the preliminary results of a TDD remote phase synchronization algorithm with a master-follower architecture. Herein, we describe the implementation and validation of the proposed algorithm. The implementation has been conducted in a Cubesat-ready software defined radio and validated at the end-to-end satellite communications testbed available at the University of Luxembourg.
