• Star density may be increased at a later date. Create even density in the constellation up
to the boundary, avoiding congestion. Sensors have a 120- degree field of view, hence,
stars placed further than the tracking area remain beneficial. Avoid mounting behind
cables or alongside structures where stars may become obscured. Stars may be mounted
at an angle or on walls if necessary.
• If you put stars onto scaffolding poles or lighting trusses, only stick middle of stars and
keep two "wings" on the side to increase the star surface seen by the sensor.
Summary
• Fixed: mounted on permanent structures
• Placed as randomly as possibly
• Differing heights: placed on at least two levels
• Well separated: spaced apart not clustered
• Clearly visible: without cables hiding stars
• Approximately 30 stars in the tracking image, minimum is 14
• Good distribution through sensor camera field of view
2.2 Star Installation Examples
An example of a 5-metre-high ceiling. The stars are positioned randomly with ideal spacing
across the ceiling and lighting grid. The reflective metal surfaces do not present a problem for
the StarTracker sensor.
