General The AL-2717-1 is a compact, high dynamic, high accuracy and high reliability direct drive tracking pedestal. The pedestal is based on direct drive technology where no mechanical gear is used. Both pedestal’s axes utilize state of the art permanent magnet synchronous motors (PMSM) and absolute angular position sensors. The motors and sensors have no moving contacts. A sophisticated Control Unit (controller/dualservo-amplifier), based on high performance DSP is incorporated in the pedestal and mounted on the rotating part of the azimuth axis. The Control Unit uses advanced PMSM control

algorithms, which provide maximal motor performance. The Control Unit has an interface with a host computer for azimuth and elevation position commands and status reports. The interface is established via high-speed RS-422 asynchronous full duplex serial communication link. The whole system is powered by 28VDC. The Pedestal’s Azimuth axis is capable of continuous rotation. For this purpose it is equipped with high MTBF slip ring assembly, which carries the 28VDC power and serial communication lines from the pedestal base to the Control Unit.

Pedestals Option & Definition

Standard Options: 1. Slip ring enabling continuous rotation for azimuth axis. When Slip-Ring and Rotary Joint are used, the limit switches are disabled. 2. Rotary-Joint assemblies, pressurized or nonpressurized, available in azimuth and elevation axes. Consult factory for specifications of rotary-joint available, i.e., frequency range, and number of channels. 3. Electrical Power Requirements: AC input voltage: 220VAC/50Hz or 115 VAC/60Hz 4. A dry air-pressurizer unit, electrically operated is available upon request. 5. Standard pedestal color is gloss-white. Other colors are available as an option. 6. Pedestals details, shown in the applicable drawings, are for reference only; and shall be specified for each order, separately. 7. All models are equipped with electrical limit switches, adjustable within the specified ranges. Primary limits satisfy normal limit stop requirements and completely independent secondary limits remove all drive power for additional protection. For limited azimuth travel, cable-wrap with sector switches are available. Elevation axis uses shock absorbing mechanical stops as a backup to the electrical limits. 8. The stow provisions consist of manuallyinterlocked and remotely-controlled stow-lock pins for azimuth and elevation axes. Elevation stowing at position 0° is optionally available. 9. This pedestal series includes standard elevation bracket. Special side-arms, counterweights and antenna mounting tables can be designed and provided according to specified User’s requirements.

10. The base riser provides the necessary clearance for a 7-meter antenna dish assembly.

Definitions: 1. Compliance: C= K = Inverse Spring Constant C = Compliance The Compliance is used to determine the mechanical resonant frequency due to elasticity of the structure, gear, drive etc. 2. Drive Unit Efficiency: µ=

Measured Output Torque Theoretical Output Torque

3. Pointing Accuracy: The pointing accuracy is the deviation between the commanded direction and the direction of the antenna. This accuracy takes into account RMS of all kinds of error. 4. Backlash: the free angular motion of the turntable due to applied external torque (usually 2% of the delivered torque) with the motor shaft locked. 5. Power Gearing Backlash: the free angular motion of the output member with the input locked. 6.

General Description: ORBIT model AL-4726-3TC is an advanced Tracking Controller, designed to provide overall control of tracking antenna motion, display position and tracking data. The AL-4726-3TC incorporates built-in solutions for a wide range of telemetry and satellite tracking applications. A variety of modes allow automatic tracking, slave tracking, manual operation and remote control via a host computer. The AL-4726-3TC has been designed for ease of parameter adjustment to allow on-site application tailoring, calibration and adjustment for mechanical and RF hardware.

Features: • A highly modular hardware design provides the reliability and maintainability required in critical application.

• Power and flexibility of a Pentium CPU along with traditional ORBIT reliability and structural integrity. • Easy to read active LCD (TFT) color display providing access to parameters for application tailoring. • Graphic, programmable scale, Error crosshair window and Signal-strength bar displays. • 0.001 degree resolution readout for actual as well as commanded angles of both Azimuth and Elevation axes. • Non-volatile memory is exclusively electronic, with reliable components. • Digital algorithms for high-bandwidth closedloop control. • A variety of tracking modes for geo-stationary satellites, low-orbit satellites and fast moving targets.

Controllers • Accurate non-volatile clock, able to be synchronized to an external time reference. • A number of general purpose system control switches: Pedestal power, Antenna Feed power, Antenna Selection, Antenna Polarization etc.

Controller operation: Manual operation Slew Knobs Two slide potentiometers and a Fine/Coarse switch are mounted on the AL-4726-3TC front panel. The potentiometers provide independent slew-rate commands for Azimuth and Elevation. A connector for an external Joystick unit can be provided as an option. When connected, the Joystick overrides the front panel potentiometers and Fine/Coarse switch, providing slew-rate commands for Azimuth axis controlled by JoystickX and Elevation axis controlled by Joystick-Y. The Fine/Coarse switch located on the controller front panel or external Joystick unit may reduce the slew-rate command scaling. Position Shaft-Encoder Knobs Two shaft-encoders are mounted on the AL4726-3TC front panel. The shaft-encoders provide independent position-step commands for Azimuth and Elevation. The Fine/Coarse switch controls the position command step scaling. Point Preset A set of ten points stored in the controller’s memory is provided. The antenna is commanded to one of the points by a single keystroke. Target Acquisition - Search Raster scanning: Synchronized movement of Azimuth scans and Elevation steps.

Zig-zag scanning: UnSynchronized movement of Azimuth and Elevation scans.

Auto-Track When in Auto-Track the AL-4726-3TC interfaces with a tracking type antenna (Monopulse, ConScan, QuadScan or others) and a tracking receiver with AM and AGC signals. These are used to extract errors both in Azimuth and Elevation, which in turn are fed into the AL-4726-3TC. Digital control loops to keep the antenna pointed at the target so that maximum RF signal is obtained at all times. The AL-4726-3TC provides a number of auxiliary functions to overcome momentary Auto-Track disruptions. All of the below listed functions are fully programmable both from the controller’s front panel and the communication link: they may be turned on or off, their parameters may be turned to optimal performance or just left to factory preset. Position Memory Upon loss of track, will bring the antenna back to the point where the target was initially acquired and try to re-acquire it again. Rate Memory Upon loss of track, will continue movement of both Azimuth and Elevation with extrapolated velocities. Launch Acquisition Will not allow Elevation axis to move downwards for predefined amount of time after the launch command. Zenith Pass For certain types of targes, when target enters the Zenith cone (predefined in terms of Elevation angles), the controller creates a mathematical model of target’s trajectory and moves the antenna to the point where the target is estimated to exit the Zenith cone. There it’s re-acquired and Auto-Track renewed.

Auto Acquire

Step-Track

When set, causes the controller to revert to AutoTrack, whenever the AGC signal crosses its Acquisition Threshold Level, regardless of the mode the controller was currently in. Comes in handy in manual target acquisition.

Periodic jogging of the antenna Up/Down and CW/CCW for repositioning to the point of the maximal reception level.

Adaptive Threshold Allows for the Auto-Track Acquisition Level to follow slow changes in the AGC signals. When utilized, adaptive threshold is set to be a few dB’s below AGC mean value, calculated over long time constant. This makes the Auto-Track less susceptible to target range variation. Back-up Mode If the target is eventually lost, the AL-4726-3TC will revert to Back-up mode, which may be programmed to one of the following: • • • • • •

Available Configurations • AL-2613-3J (Basic unit without Servo Amplifiers, to be used with pedestals having built-in Servo Amplifiers). • AL-2613-3J-OSA (with one built-in servo amplifier) • AL-2613-3J-DSA (with dual built-in servo amplifiers)

Front Panel Operation The AL-2613-3J front panel contains 3 pushbuttons, joystick, fine/coarse switch, azimuth and elevation position displays, and remote /

local LEDs, making it a self-contained unit for manual operation. One cable control and feedback is connected from the AL-2613-3J to the pedestal. The AL2613-3J is connected to its power source, which can be 115VAC, 230VAC or 24VDC. Upon powerup, the controller performs home sequence and is then ready to use. A remote/local pushbutton allows the user to select local (joystick) control or remote (slave) control. Change between local and remote control automatically brings the pedestal to standby mode. An offset pushbutton allows the operator to adjust the azimuth reading for true north. A calibrate pushbutton allows the operator to activate the home sequence. The joystick allows simultaneous motion of both axes and has specially tailored profile to allow control of fine position for small displacements while still allowing rapid motion for full displacement.

Remote Operation The unit can be remotely controlled by sending simple ASCII strings to the serial port. The unit is supplied with a simple test routine that runs on PC, allowing the operator to tune various operating modes. Using RS-422 communication, the remote control computer may be as far as 2Km from the AL-2613-3J controller. In addition,

Controllers control commands can be performed through a modem between any points where telephone access is available.

Modes of Operation Standard modes of operation are: standby, home, slave tracking, slew and calibrates. Optional additional modes include search, orbit, and step-track. In all modes, the velocity and acceleration are limited to the values placed in the parameter set, preventing shock to equipment in case of sudden changes in the commanded slave trajectory.
