SPS-250 & SPS-350
Cost-Effective, High-Performance Positioning Systems
Atlantic Positioning Systems has developed a series of small positioners for airborne and ground mobile applications. As in the remainder of the product line, the positioners are direct drive brushless motor based gimbals with brushless resolvers and rugged construction for military applications. Combined with a proprietary control system design, the SPS-250 and SPS-350 offer a turnkey terminal requiring only power, a communications port and a signal I/O to implement an RF or E/O solution. Applications include SATCOM-On-The-Move, Mobile Datalink, Lasercom, E/O imaging, laser beam control and ESM systems. These positioners can be combined with antennas from sister divisions to implement SATCOM, Datalink and ESM subsystems scalable to a wide variety of performance requirements.

Technical Description
The APS SPS-250/350 has been developed for the On-The-Move market. The modular design makes it easily adaptable for a large variety of Antennas, EO Sensors, Mirrors and Laser Beam Sources by varying the yoke design (or T-Bar) with minimal NRE. The application flexibility shown on the following page shows the adaptability to varied platforms and payloads. Combined with the possibility of integrating the Micro Digital Controller (MDC) into the positioner, the ability to walk away with a turnkey terminal is very attractive.
The rugged design combined with MIL Grade Fiber Optic Gyros make this an ideal source for stabilized gimbals for ground, air or shipboard platforms. The use of brushless motors and resolvers directly coupled to the payload eliminates backlash, reduces jitter, achieves high reliability and meets MIL-STD-810 & RTCA/DO-160 environments. The direct drive system also allows the gimbal to achieve high rates of acceleration for near zenith targets for tracking applications.
