Pan-Tilt Unit D48E ISM Overview
The PTU D48E ISM provides stabilized pointing for virtually any type of payload. The integrated MEMs sensor is used by the ISM processing module to measure platform motion in real-time, and to dynamically control the pan-tilt to compensate for unwanted motion. Its light weight make it suitable for airborne as well as fixed or ground mobile/portable applications. The real-time control interface allows applications to dynamically control the PTU D48E ISM while stabilized, to support applications such as slew-to-queue, video tracking, antenna tracking, and more.
The controller is fully integrated. A single mil-style connector provides power and pan-tilt control, as well as payload signal management (optional). Integrated flex-circuitry absorbs tilt motion for all internal wiring to provide long life over high duty cycles.
The built-in command set offers both ASCII and binary formats. This command set supports real-time control at up to 60 commands/second with very low and predictable latencies. The rich command set provides fine-grained control of position (absolute and relative), velocity, acceleration and other unit functions. The optional Geo-Pointing Module also provides an Ethernet/IP interface for control of the pan-tilt units.
