PTU-D300-RF
Antenna positioner
Rugged, flexible, feature-rich
|
The
PTU-D300-RF provides fast, accurate positioning of antennas
and other payloads.
Featuring a DC-18Ghz RF rotary joint and slip-ring to allow continuous
pan rotation, it provides high torque for payloads up to 31.7 kg
while maintaining speed, precision, and a small form factor.
The real-time control capabilities make the D300-RF ideal for tracking
applications. Designed for durability in harsh environment such
as air, ground or sea vehicles, the D300-RF is suited for demanding
applications that require high duty-cycles and long-life in harsh
all-weather environments. |

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 |
