AL-2717-1EL/AZ Direct DriveTracking Pedestal

27

General

The AL-2717-1 is a compact, high dynamic, highaccuracy and high reliability direct drive trackingpedestal. The pedestal is based on direct drivetechnology where no mechanical gear is used.

Both pedestal’s axes utilize state of the artpermanent magnet synchronous motors (PMSM)and absolute angular position sensors. Themotors and sensors have no moving contacts.

A sophisticated Control Unit (controller/dual-servo-amplifier), based on high performanceDSP is incorporated in the pedestal and mountedon the rotating part of the azimuth axis. TheControl Unit uses advanced PMSM control

algorithms, which provide maximal motorperformance.

The Control Unit has an interface with a hostcomputer for azimuth and elevation positioncommands and status reports. The interface isestablished via high-speed RS-422 asynchronousfull duplex serial communication link. The wholesystem is powered by 28VDC.

The Pedestal’s Azimuth axis is capable ofcontinuous rotation. For this purpose it isequipped with high MTBF slip ring assembly,which carries the 28VDC power and serialcommunication lines from the pedestal base tothe Control Unit.

Measured Output TorqueTheoretical Output Torque

3. Pointing Accuracy: The pointing accuracy is thedeviation between the commanded directionand the direction of the antenna. This accuracytakes into account RMS of all kinds of error.

4. Backlash: the free angular motion of theturntable due to applied external torque(usually 2% of the delivered torque) with themotor shaft locked.

5. Power Gearing Backlash: the free angular motionof the output member with the input locked.

6. Orthogonality Error: The angular amountresulting from the deviation of the elevationaxis from its theoretical position (which isperpendicular to the azimuth axis).

7. Data Takeoff Accuracy : The space differencebetween the actual position (measured byoptical device) and the position displayedon controller screen (under no load).

8. Readout Error: the difference between theturntable position to the data take off readout(controller) for each axis.

9. Static Error, Position Error: The maximum errorwith no motion.

10. Tracking Error: The difference between theantenna beam to the direction of the RFsource.

11.Dynamic Error: The difference between theactual position to the commanded position.

Controller operation:

Manual operation

Slew Knobs

Two slide potentiometers and a Fine/Coarseswitch are mounted on the AL-4726-3TC frontpanel. The potentiometers provide independentslew-rate commands for Azimuth and Elevation.

A connector for an external Joystick unit can beprovided as an option. When connected, theJoystick overrides the front panel potentiometersand Fine/Coarse switch, providing slew-ratecommands for Azimuth axis controlled by Joystick-X and Elevation axis controlled by Joystick-Y.

The Fine/Coarse switch located on the controllerfront panel or external Joystick unit may reducethe slew-rate command scaling.

Position Shaft-Encoder Knobs

Two shaft-encoders are mounted on the AL-4726-3TC front panel. The shaft-encoders provideindependent position-step commands for Azimuthand Elevation.

The Fine/Coarse switch controls the positioncommand step scaling.

Point Preset

A set of ten points stored in the controller’smemory is provided. The antenna is commandedto one of the points by a single keystroke.

Target Acquisition - Search

Raster scanning: Synchronized movement ofAzimuth scans and Elevation steps.

Zig-zag scanning: UnSynchronized movement ofAzimuth and Elevation scans.

Auto-Track

When in Auto-Track the AL-4726-3TC interfaceswith a tracking type antenna (Monopulse,ConScan, QuadScan or others) and a trackingreceiver with AM and AGC signals. These areused to extract errors both in Azimuth andElevation, which in turn are fed into theAL-4726-3TC.

Digital control loops to keep the antenna pointedat the target so that maximum RF signal isobtained at all times.

The AL-4726-3TC provides a number of auxiliaryfunctions to overcome momentary Auto-Trackdisruptions. All of the below listed functions arefully programmable both from the controller’sfront panel and the communication link: theymay be turned on or off, their parameters maybe turned to optimal performance or just leftto factory preset.

Position Memory

Upon loss of track, will bring the antenna backto the point where the target was initiallyacquired and try to re-acquire it again.

Rate Memory

Upon loss of track, will continue movement ofboth Azimuth and Elevation with extrapolatedvelocities.

Launch Acquisition

Will not allow Elevation axis to move downwardsfor predefined amount of time after the launchcommand.

Zenith Pass

For certain types of targes, when target entersthe Zenith cone (predefined in terms ofElevation angles), the controller creates amathematical model of target’s trajectory andmoves the antenna to the point where thetarget is estimated to exit the Zenith cone.There it’s re-acquired and Auto-Track renewed.

31

Auto Acquire

When set, causes the controller to revert to Auto-Track, whenever the AGC signal crosses itsAcquisition Threshold Level, regardless of themode the controller was currently in. Comes inhandy in manual target acquisition.

Adaptive Threshold

Allows for the Auto-Track Acquisition Level tofollow slow changes in the AGC signals. Whenutilized, adaptive threshold is set to be a fewdB’s below AGC mean value, calculated overlong time constant. This makes the Auto-Trackless susceptible to target range variation.

Back-up Mode

If the target is eventually lost, the AL-4726-3TCwill revert to Back-up mode, which may beprogrammed to one of the following:

• Slave Position• Orbit or Ephemeris Track• Stand-by• Manual Slew or Position• GPS-Track• Search or re-acquire

Tracking A.canMonopulseElectronic Scan

Dual Antenna Tracking

Two antennas are utilized, a high-gain-narrow-beam tracking antenna and a low-gain-wide-beam antenna acquisition. The AL-4726-3TCautomatically selects between the antennas foroptimal target acquisition and trackingperformance as well as side-lobe lockingprevention.

Dual receiver Tracking, Auto- Diversity

The controller has option for two receiver inputsfor AGC and AM.

The controller is constantly monitoring tworeceiver AGC signals. Receiver with most AGC isautomatically selected for tracking.

Step-Track

Periodic jogging of the antenna Up/Down andCW/CCW for repositioning to the point of themaximal reception level.
