Claim 7:
8. The tracking system according to claim 1, wherein at least one of:
a) the at least three tracking heads are spaced apart by at least one of:
i) 100 mm to 1000 mm;
ii) 250 mm to 750 mm; and,
iii) about 500 mm; and,

b) the at least three targets are spaced apart by at least one of:
i) 100 mm to 1000 mm;
ii) 250 mm to 750 mm; and,
iii) about 500 mm;

c) the at least three targets are mounted on at least one of:
i) a target support; and,
ii) directly on the object;

d) the position of the multiple targets relative to the object is fixed;
e) the targets are rigidly mounted to the object and wherein the control system selectively switches tracking of targets to maintain line of sight between the tracking heads and targets;
f) each target is a spherically mounted retroreflector (SMR); and,
g) the tracking head support:
