Similar to the StarBot 4200, the StarBot 4300 is a portable test system designed for antenna testing of aircrafts or vehicles in-situ. Improving upon its predecessor, in addition to the high measurement flexibility for radar testing in the nose of an aircraft, its full robotic system and 6 positioning axes enable it to measure antennas anywhere on an aircraft (or vehicle): top, bottom, nose, tail, wings, etc. The StarBot 4300 is designed to characterize antennas without displacing the device under test and without enclosure in an anechoic chamber. It is the ideal spherical near-field...

# System overview INSTRUMENTATION ROOM CHAMBER USB Mixer Unit StarBot 4300 is composed of a mechanical scanner paired with our patented MV-ScanTM probe array of 126 dual polarized 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...

The overall system is composed of: The base trolley The base trolley moves the scanner to the measurement area. It is mounted on four independent, directional wheels (A, B, C, D). Once in position, four jacks (K) lock the trolley to the ground. The telescopic arm The telescopic arm holds the spherical probe array and provides four independent movements. An azimuth table (E) ensures the rotation of the upper part of the trolley. An arm (G) lifts the probe array which can be elevated with an electrical actuator. Finally, a tilt axis positions the probe array in place. The measurement scanner...
