Abstract

A system comprising a ground-based station comprising a first data store, where the first data store stores operational characteristics of a space-based station, where the space-based station comprises a second data store that mirrors the first data store at a first time. The ground-based station is configured to generate first log data based on a determined type of activity performed by the user at a second time. The system further comprises a user device located on the space-based station and configured to determine a second type of activity performed by the user at the space-based station at the second time; generate second log data based on the determined second type of activity performed by the user; process a synchronization request received from the ground-based station; identify a conflict between the first and second data logs; and in response to identifying the conflict, select one of the data logs are accurate.

Description

BACKGROUND Computing devices can utilize communication networks to exchange data between nodes in a terrestrial environment and space-based environment. Commercial and international organizations operate computer networks that interconnect a number of computing devices to support operations or to provide services to third parties (such as in-situ resource utilization, scientific experimentation, and mining operations). The computing devices can be located in a single geographic location, located in multiple, distinct geographic locations (e.g., interconnected via private or public communication networks), or in a space-based environment.
