INTRODUCTION INTRAC-305 INTRODUCING THE INTRAC-305 The INTRAC-305 INtelligent TRacking Antenna Controller is a microprocessor based controller for tracking any nominally geostationary satellite including those at low elevation or with high angles of inclination. It has been designed as a direct physical replacement for the Andrew APC300 Steptrack Controller. For information on replacing an Andrew APC300 with the INTRAC-305 see section 6 - Installation.
INTRAC-305 INTRODUCTION A Typical System The antenna position resolvers provide direction information to the INTRAC. The IBR-L (beacon receiver) provides tracking signal strength. (A signal strength derived dc voltage from an external receiver may be used in place of the Advantech AMT IBR-L) The Motor Drive Cabinet receives the antenna drive commands from the INTRAC and drives the azimuth, elevation and polarisation (option) motors and brake assemblies.
IQUICK START GUIDE A suggested quick INTRAC-305 start procedure is given below: 1/ Before modifying system make a note the antenna pointing angles from the old tracking system. 2/ Perform any recommended resolver mounting bracket modifications. 3/ Connect INTRAC-305 in place of Andrew APC300 and check that the Fitted Options (Home>Function>System Setup>Fitted Options) (Manual page 39) are set correctly.
INTRAC-305 QUICK START GUIDE If an IBR-L is not fitted then provide a voltage signal to the beacon 1 input. You will need to adjust the potentiometers (See manual page 76) to set the gain and offset to the correct values. Manually peak the antenna to maximize the beacon level and check that the beacon does not overload (24.9 dB displayed). 11/ Set any other parameters, such as Soft Limits. 12/ Select Auto-New Model (Home>New Mode>Auto New Model) and press enter.
SAFETY 1. INTRAC-305 SAFETY WARNING POSSIBLE LETHAL POTENTIALS EXIST WITHIN THIS EQUIPMENT THE COVERS SHOULD NOT BE REMOVED EXCEPT BY QUALIFIED PERSONNEL. SWITCH OFF POWER AND ISOLATE SUPPLY BEFORE REMOVING COVERS. IF IT IS NECESSARY TO OPERATE THE EQUIPMENT WITH THE COVERS REMOVED FOR SERVICING PURPOSES ALL NECESSARY PRECAUTIONS SHOULD BE TAKEN TO PROTECT AGAINST ELECTRIC SHOCKS ELECTRICAL Fusing The standard unit is protected by a user replacable fuse in the live/phase power supply line.
1 INTRAC-305 SAFETY Facilities exist at the Motor Drive Cabinet for the connection of external emergency stop switches. It is highly recommended that those fitted be of the latching type. MECHANICAL Mounting The INTRAC-305 must not be mounted so that it is supported only by the front panel. A proper rack mounting kit must be used. This may be either of the fixed mounting type or the sliding rail type.

3 INTRAC-305 3. OPERATION OPERATING THE INTRAC-305 The INTRAC-305 may be operated directly from the front panel or from the (optional) Remote Control and Monitoring Terminal. For both methods of operating a series of menus enables a user to program the INTRAC and to invoke its modes of operation. Operation from the front panel is described in this section of the manual. The (optional) remote terminal (the RCM-4) is described in the appendices.
OPERATION INTRAC-305 Emergency Stop Button Pressing the button removes all drive from the antenna. The button locks in the safe position when pressed. To enable drive to return to the antenna the button must be rotated clockwise until it releases. On/Off Switch Illuminated rocker switch to apply power to the INTRAC-305. Illuminated when the INTRAC is on. On Dual Redundant PSU units the rocker switch is replaced by status LEDs.

OPERATION INTRAC-305 NORMAL OPERATION Continuing Tracking With the INTRAC-305 operating normally it will be in Tracking Mode and will require no operator input. Should it become necessary to move the antenna off satellite for some reason, such as to stow it because of wind, all that is required to resume tracking is to select Auto Continue. (after the antenna has been unstowed) To Track a new Satellite Set the Beacon Frequency. Set the Polarisation angle if motorised Pol fitted.
4 INTRAC-305 4. ALARMS & ERRORS ALARMS & ERRORS The INTRAC-305 has two type of alarm condition. Primary Alarms and Secondary Alarms. The system will go into Standby mode if a Primary Alarm is triggered. Secondary Alarms leave the INTRAC in its current mode. PRIMARY ALARMS A Primary Alarm becomes active if one (or more) of the following conditions arise : Drive Fail Alarm Antenna movement limit switch activated. Software limit tripped. Emergency Stop button operated.
ALARMS & ERRORS SECONDARY ALARMS INTRAC-305 There are three Secondary Alarms : Unable to Predict Unable to Predict Alarm. Beacon Alarm. Servo Alarm. This alarm is raised when the INTRAC has not enough confidence in the orbit model to be able to predict the satellites position. e.g. during the early part of learning a new model or after there had been no beacon signal for more than 72 hours.
4 INTRAC-305 POWER FAILURE ALARMS & ERRORS The INTRAC incorporates non-volatile memory and a battery backed real time clock. The onset of a power failure is detected and the current mode is stored before the processor ceases to operate. When power is restored the INTRAC performs an automatic recovery as below :If the unit was in Auto (Tracking) Mode at the time of the power failure and no Primary Alarms have become active the unit will resume tracking.

5 INTRAC-305 5. TECHNICAL DESCRIPTION TECHNICAL DESCRIPTION This section looks at and explains the Operational Modes and Functions of the INTRAC-305 and at the tracking algorithm that makes the INTRAC-305 one of the most accurate tracking antenna controllers available. The INTRAC-305 achieves its very high accuracy satellite tracking by building a model of the satellite’s orbit and then by using that orbit model to direct the antenna.
TECHNICAL DESCRIPTION INTRAC-305 the raw satellite position estimate and the orbital model is filtered with another tracking filter (known as the "relationship algorithm") capable of tracking and correcting transients. This is then combined with the basic model to form a reliable predictor that tracks mean windage, refraction and stationkeeping manoeuvres without error.
5 INTRAC-305 TECHNICAL DESCRIPTION component of beam shift is not visible to the position transducers. The mean of the reference shift is tracked by the INTRAC algorithm in a similar way to a stationkeeping manoeuvre. The component of beam shift that is visible to the position transducers is entirely tracked by INTRAC within a 10 MHz noise bandwidth. When the position transducers accurately reflect beam deflection in wind INTRAC continuously tracks this antenna deflection at 16 sec updates.
TECHNICAL DESCRIPTION Standby INTRAC-305 Auto - (tracking but includes learning & predicting) Manual Goto - (Goto Satellite, Goto Position & Search) Sleep - (alarm induced, not user selectable) Remote (transfers control to a remote terminal) Standby mode is a “no movement” mode, the antenna is not driven (the brakes where fitted will be applied) but the pointing angles and beacon signal level are monitored and displayed.
5 INTRAC-305 TECHNICAL DESCRIPTION the high accuracy of the model the tracking is within 0.05dB of peak signal tracking. In Tracking Mode the INTRAC continuously updates the model by making small perturbations of the antenna and incorporating the resultant data into the model. During periods when the satellite’s orbit is changing because of station keeping manoeuvres the INTRAC may increase the frequency of the perturbations.
TECHNICAL DESCRIPTION INTRAC-305 within the soft limits?). If they are invalid the INTRAC sets the maximum possible angle(s) in the required direction and prompts the operator for action. If the co-ordinates are valid the INTRAC drives the antenna to those co-ordinates and enters Standby. The antenna can then be peaked using manual mode or search mode (see below) before selecting Auto New Model.
5 INTRAC-305 TECHNICAL DESCRIPTION strength is recorded and at the end of this phase the antenna is driven to that position and the INTRAC enters Standby. At this point the peak may be confirmed manually and/or learning mode entered by selecting Auto New Model. Remote Remote Mode transfers control of the INTRAC to a remote terminal. It is selected with Menu Key 6 (Select Remote) from the Home menu. Once in Remote Mode only four functions are available from the INTRAC front panel.
TECHNICAL DESCRIPTION INTRAC-305 IESS Minutes Interval range: 0 to 59 IESS Days Validity range: 0 to 28 IESS Sat LM0 range: 0 to 360 deg IESS Sat LM1 range: -9.99 to 9.99 deg/day IESS Sat LM2 range: -9.99 to 9.99 deg/deg/day IESS Sat LONC range: -9.99 to 9.99 deg IESS Sat LONC1 range: -9.99 to 9.99 deg/day IESS Sat LONS range: -9.99 to 9.99 deg IESS Sat LONS1 range: -9.99 to 9.99 deg/day IESS Sat LATC range: -9.99 to 9.99 deg IESS Sat LATC1 range: -9.99 to 9.
5 INTRAC-305 TECHNICAL DESCRIPTION negative when entering from the front panel. This only applies to the LMO data field. NORAD data The NORAD ephemeris data consists of a string of 166 characters. The first 160 characters are split into two “Card Element Sets” of 80 characters each. The next two characters (161 & 162) comprise the Minutes Interval and characters 163 & 164 comprise the Period of Validity of the ephemeris. The final two characters (165 & 166) are the check sum.
TECHNICAL DESCRIPTION INTRAC-305 The Basic algorithm available in the Rapid Model Generation table is not of NORAD origin. It has none of the embellishments found in the NORAD routines and is meant for test purposes only. Once the orbital model has been built using the ephemeris data the INTRAC tracks the satellite from it and updates and improves it over the following hours and days.
5 INTRAC-305 TECHNICAL DESCRIPTION illuminated. The alarm may be viewed using the Show Alarms menu. The Soft Limits are set in the Configuration - Soft Limits menu. Note In either Manual (P) or Manual (A) mode the antenna may be driven through the soft limits with no warning. AXES POSITION Resolver units are fitted to the driven axes of the antenna. These units supply positional information to the INTRAC’s resolver interface circuits.

6 INTRAC-305 INSTALLATION Beacon Signal Connector When an IBR-L beacon receiver is fitted there will be a “N-type” RF connector on the INTRAC rear panel. It is to this that the beacon signal is connected. Note 18Vdc may be connected to the inner connector of the N-type in order to power the Block Down Converter. The 18V can be removed from the “N” connector by power connector J41 on the INTRAC Interface board.
INSTALLATION INTRAC-305 Selection of Southern or Northern Hemisphere within the INTRAC is automatic based on a positive or negative input for Latitude in System Setup - Station Co-ordinates. TRACKING SIGNAL INPUT The tracking signal may be provided as a dc voltage from an external receiver or from the optional IBR-L internal receiver. With IBR-L The IBR-L requires a L-band beacon signal at a level within the range -80dBm to -45dBm with a carrier to noise ratio (C/No) of better than 40dBHz.
6 INTRAC-305 INSTALLATION Finally adjust R55 to read +20dB when the maximum clear sky tracking signal is being received. Note It may be necessary to adjust the links J31 depending on the polarity of the tracking signal. The link options are both links should be either vertical or horizontal. OPERATIONAL CHECKS Manual Operation This test checks the operation of the motor drives and limit switches. Ensure that all limit and interlock switches are in the normal operating condition. Switch on the INTRAC.
INSTALLATION INTRAC-305 If external emergency stop switches are fitted check their operation in the same way. It must not be possible to re-start any motor whilst any emergency stop switch is in the operated state. Auto Operation After manually pointing the antenna towards the required satellite use the Search facility to peak the antenna on the satellite. Check that this function works correctly.

SWITCH OFF POWER AND ISOLATE SUPPLY BEFORE REMOVING COVERS. IF IT IS NECESSARY TO OPERATE THE EQUIPMENT WITH THE COVERS REMOVED FOR SERVICING PURPOSES ALL NECESSARY PRECAUTIONS SHOULD BE TAKEN TO PROTECT AGAINST ELECTRIC SHOCKS Introduction Advantech AMT Limited recommend that users return faulty INTRAC-305 units to Advantech AMT Ltd.
FAULT FINDING INTRAC-305 This fault finding guide goes no further than the replacement of the major assemblies such as power supply, IBR-L or complete printed circuit assemblies. The INTRAC-305 consists of six major assemblies : Note Main Interface PCB Processor PCB Low voltage power supply LCD Display panel Front panel keys assembly Beacon receiver (optional) The LCD display panel has a replaceable backlight which has a finite life span.
7 INTRAC-305 FAULT FINDING Disconnect the two lamp wires from the orange connector at the front corner of the Interface PCB. Disconnect the LCD panel flex cable from Connector J64 on the Interface PCB. Remove the four screws which hold the INTRAC front panel to the sides and drop down the front panel. Remove the four nuts which hold the display assembly to the front panel and remove the display unit from the front panel. Lay it face down on a soft surface.
FAULT FINDING INTRAC-305 Install new lamp and wire assembly. Wrap reflector sheet around lamp. Replace securing tapes to secure reflector. Turn unit face up and ensure that backlight is free from contamination - dust may be blown free. Slide backlight into display unit. Replace metal cover over backlight. Replace retainers, press centre to secure. Locate display unit over the four studs and fit the nuts. Re-fit INTRAC front panel to side panels, reconnect flex cable and lamp wires.
7 INTRAC-305 FAULT FINDING wrong angle displayed angle doesn’t change when antenna is moved No Antenna Drive If all the angles are changing the fault is on the Interface PCB. If the displayed angle changes to be near 0 or 90 it is probable that one of the two return signal circuits from the resolver is broken or the resolver itself is faulty. If the displayed angle changes to any angle other than near 0 or 90 the fault is on the Interface PCB.
FAULT FINDING Tracking Signal (IBR-L) INTRAC-305 If the beacon signal falls to a non-usable level the INTRAC automatically enters Predicting Mode and continues to track the satellite from the model. There is no way of knowing from the INTRAC whether the loss of signal is due to the satellite or the IBR-L. Thus when the displayed beacon level falls below normal the user should check the signal by some other means before assuming an IBR-L problem.
