| The Canadian Space Vision System (CSVS). The Canadian Space Vision System uses Shuttle or Space Station TV cameras as sensors. These cameras monitor a pattern of special target dots placed on the object to be tracked. As the object moves, the Canadian Space Vision System tracks the changing position of the dots, calculates the location and orientation of the object, and presents this infomation to the operator in the form of both graphical and textual cues. This information can be used to position and orient a payload using the Canadarm or the Space Station Remote Manipulator System, or to join two objects as in the case of Space Station assembly.
The Canadian Space Vision System has many enhanced features which increase the accuracy, versatility and usefulness of the system. The Canadian Space Vision System is now able to operate in a wider range of lighting conditions. Frequent periods of extreme dark or bright light make it difficult for those working in space to gauge the distance and speed of objects such as satellites. With the addition of improved target tracking features, the Canadian Space Vision System is able to switch from one set of targets to another when one moves out of its field of vision. The Canadian Space Vision System is also capable of "losing" targets as they become obscured, allowing the calculations to continue on the remaining targets. For some operations, the Canadian Space Vision System can also overcome conditions such as the Shuttle turning or shaking, and assist in berthing manoeuvres of an object in space.
