SPS-6000

SPS-6000 Precision Positioners

The SPS-6000 was developed for large imaging telescopes and beam directors and is capable of deploying as a mobile E/O System and can be configured as a Coude’ path gimbal. Trailer supplied as a custom configuration with a shelter if required. Nominal bearing wobble and orthogonality is 20 arcsec RMS. Mechanical errors can be reduced by modeling in software.
