GPS AUTOMATIC TRACKING PEDESTALS

The OS-PT family of GPS Automatic tracking systems have been designed to provide GPS based positioning of high-gain antenna systems to support realtime airborne video and telemetry transmission requirements. The automatic tracking pedestal systems are based on heavy duty ruggedized Pan and Tilt pedestal that provides large output torque on each axis. Heavy duty ball bearings supporting the output shaft allow it to accommodate heavy payloads under wind and heavy gust conditions. Each axis includes a DC brushless stepper motor coupled to very low backlash harmonic gearing. It is designed to allow stalling of the output shafts without damage to the gears, the motors, or control electronics. The tracker units are air-filled and were original designed for under water operations. The units are excellent for above water applications where rain, humidity and dust are main issues

The OS-PT utilizes a RS-485 communications protocol which provides several advantages over RS-232. RS-485 allows communication over longer lengths of cable (1000 feet) and enables the ability for networking multiple nodes. Multiple trackers can be controlled over the same cable.One cable assembly with a total of four wires (two for power; two for communication ) is required to operate the RS-485 / RS-232 tracking system.

All OS-PT systems have been fully integrated with Silvus Technology' MIMO radios, including the 2X2 SC4200 and 4X4 SC4400; Piccolo flight control system from Cloud Cap Technology (CCT) and FlighTEK from L3 Communication Geneva Aerospace. The tracking system operates directly from Piccolo Command Center ,MissionTEK as well as OS standalone antenna tracker software.

The system is delivered as a turn-key solution, complete with cable assembly,specific antennas, power supply, Hercules heavy duty tripod,containers and RS-232 to RS-485 to USB converter.

OS-PT-25
The OS-PT-25 provides 45 lb-ft (61 N-m) of output torque on each of its two axis. It may be fitted with a variety of antennas depending on the frequency of operation, polarity, and gain requirements of the system. Up to 48 inches large RHCP dishes, high-gain omni for diversity receive, and up two Yagi antennas for data comms, can easily be utilized.
