This Defense Intelligence Reference Document, DIA-08-1101-001, is dated 15 December 2010. The Defense Intelligence Agency's Defense Warning Office produced it under the Advanced Aerospace Weapons System Applications program. It asks how many unmanned spacecraft one pilot could control in a future deep-space fleet, drawing on air traffic control and multiple unmanned vehicle research. It concludes the limits are about 16 craft for simple tasks, 7 for moderately complex ones and 4 for complex heterogeneous craft. It adds that physiological measures can signal operator overload.
From the source: Release of 2026-09-18 Incident: 12/15/10, Las Vegas, Nevada. Released with redactions. This document is a Defense Intelligence Reference Document (DIRD), a technical reference format used by the Defense Intelligence Agency (DIA) to capture baseline knowledge on a specific topic for later analytic use. DIRDs are best understood as reference and synthesis products rather than as original research. It is one of 38 DIRDs produced under the Advanced Aerospace Weapon System Applications Program (AAWSAP) between 2009 and 2011. Because AAWSAP’s scope permitted a broad range of supporting topics, not every DIRD in the series directly concerns aerospace systems or future threat assessment. The following summary reflects the DIRD’s scope and framing at the time of writing and should not be read as implying current validation of the concepts discussed. This DIRD examines how many unmanned spacecraft a single human operator could realistically supervise or control at once, using research from air traffic control and multi-vehicle remote piloting as rough analogs. The report argues that the practical limit depends heavily on task complexity: about 16 craft for simple monitoring or destination assignment, about 7 for moderately complex piloting or mission tasks, and about 4 for complex heterogeneous operations. It places particular emphasis on the operator’s ability to maintain a coherent mental “big picture” of multiple vehicles at once, and it suggests that automation and external displays can help by offloading working-memory demands, though not eliminating them. The document also highlights physiological workload measures as a possible way to detect or predict operator overload in real time. Overall, it presents multi-spacecraft control as a human-factors and systems-integration problem in which progress depends on managing cognitive limits through interface design, automation, and workload monitoring.
UNCLASSIFIED/ /FOR OFFl@IAL Y!H! 8HL'I Cognitive Limits on Simultaneous Control of Multiple Unmanned Spacecraft Summary Space exploration 40 years into the future may include manned missions to parts of the outer solar system. A possible scenario may include sending a small fleet of craft with different primary missions. For example, a trailing spacecraft of nuclear powered electromagnets designed to shield the manned part of the fleet from solar radiation; halo spacecraft with powerful radars to scout for incoming objects; exploration and mining craft, etc. The fleet could regularly travel out of unaided visual range of each other, joining up when necessary for maintenance, exchange of materials such as fuel, or other necessities. Piloting these multiple craft could be economically accomplished if only one remote pilot on station at a time was necessary. The cognitive limitation of a human astronaut and his ability to perform the multiple vehicle piloting task is the focus of this paper as little work has been done in this specific area. However, a large body of cognitive research on the limitations of object supervision and tracking for the task of air traffic control (ATC) exists. Additionally, there is an emerging body of research concerned with multiple unmanned vehicle piloting for heterogeneous missions. These are the two areas reviewed in detail as they relate to possible spacecraft missions. Pilots develop an internal mental representation of the identity, position, mission, and current direction of relevant objects. This is referred to colloquially as "the big picture." The primary research question we seek to answer is whether there is a cognitive limit to the number of objects that can be monitored and tracked within the big picture. Secondarily, we seek to find whether this maximum number is limited by the complexity of interaction; how those limiting factors are described, whether there is a real-time objective measure that indicates when a pilot is approaching his maximum capacity, and whether that capacity has been exceeded. The maximum number of tracked objects is highly dependent on the complexity of the piloting and mission tasks at hand. Research is lacking in the area of cognitive limits on the number of spacecraft one pilot could control given any mission scenario. Currently, two models are being used to examine similar activities in air traffic control and remote piloting of multiple unmanned vehicles. In both areas it has been shown the cognitive limits on the number of craft capable of simultaneous control is 16 for simple destination selection, 7 for moderately complex piloting and/or mission task completion, and 4 for complex heterogeneous craft. While additional future research may help to increase the automation component of aircraft and mission control, no current evidence exists to show that a complete mental picture can be maintained for more than about 16 objects at one time, even with external working memory augmentation. However, it has also been demonstrated that physiological variables can be objectively employed to indicate overload. Nominal success has been achieved in classifying physiological states near high workload thus enabling both prediction and possibly prevention of overload.
