Antenna Range Alignment

Compact Range – feed focus and alignment

Tapered Range – symmetry and chamber axial ratio

Rectangular Range - symmetry

Outdoor Ranges (elevated, ground reflection) – symmetry, alignment, fence placement, tower height

Laser corrected probe-rail measurements for accurate phase data

Test Positioner

Alignment of the test positioner polarization axis to the planar wave front

Establishing a reference (optical or other) tying the range axis to the test positioner roll axis

Positioner feedback verification utilizing a tracking laser or optical device

Positioner backlash measurement

Positioner stack-up orthogonality, intersection and alignment to source polarization axis
