ORBIT FR StarBot 4300 - Manual (Page 3)

74
StarBot 4300 is composed of a mechanical scanner paired
with our patented MV-Scan
TM probe array of 126 dual pola-
rized probes. The probes are distributed over half an arch
of 6m in diameter. The 6 axes enable flexible positioning so
as to access antennas placed anywhere on an aircraft. The
system is driven by a full remote control robotic system to
facilitate displacements and positioning.
One spherical dimension is measured by an electronic
scanning of the probes at a very high speed. The other
dimension is obtained by a simple rotation of the arch
around the first to last probe axis. The goniometric axis
allows for oversampling. The aircraft itself is the only limita-
tion to completing the 360°. Measurements can be perfor-
med in CW or pulsed mode thanks to a network analyser.
