  As an emerging approach to space situational awareness and space imaging, the
practical use of an event-based camera in space imaging for precise source
analysis is still in its infancy. The nature of event-based space imaging and
data collection needs to be further explored to develop more effective
event-based space image systems and advance the capabilities of event-based
tracking systems with improved target measurement models. Moreover, for event
measurements to be meaningful, a framework must be investigated for event-based
camera calibration to project events from pixel array coordinates in the image
plane to coordinates in a target resident space object's reference frame. In
this paper, the traditional techniques of conventional astronomy are
reconsidered to properly utilise the event-based camera for space imaging and
space situational awareness. This paper presents the techniques and systems
used for calibrating an event-based camera for reliable and accurate
measurement acquisition. These techniques are vital in building event-based
space imaging systems capable of real-world space situational awareness tasks.
By calibrating sources detected using the event-based camera, the
spatio-temporal characteristics of detected sources or `event sources' can be
related to the photometric characteristics of the underlying astrophysical
objects. Finally, these characteristics are analysed to establish a foundation
for principled processing and observing techniques which appropriately exploit
the capabilities of the event-based camera.
