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. The INTRAC-305 builds

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. Limit switches on

IQUICK START GUIDE INTRAC-305 A suggested quick 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. Note that the resolvers used with the APC300 system were normally x2 re

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.

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. EMC The unit is designed to meet the requirements of the EC EMC

2 INTRAC-305 SPECIFICATION & OPTIONS 2. SPECIFICATION & OPTIONS The following pages contain the specification of the INTRAC- 305, a list and description of the available options and a chart of the delivered configuration. Required Mechanical Characteristics of the Antenna System To enable the full tracking performance of the INTRAC-305 the antenna system must conform to certain overrun and tracking constraints. 1 The tracking drive speed must be less than / of the 1

SPECIFICATION & OPTIONS INTRAC-305 SPECIFICATION Tracking Accuracy Typically <0.1dB RMS signal degradation after tracking for 30minutes (with tracking signal). Prediction Accuracy Typically <0.1dB RMS signal degradation over 72hrs (after loss of tracking signal). Tracking Signal May be derived from an external tracking receiver or from the (optional) Integral Beacon Receiver (IBR-L). External DC voltage varying directly with received signal strength (in dB).

2 INTRAC-305 SPECIFICATION & OPTIONS Position Offset The indicated pointing angles can be electrically offset in all axes to an accuracy of 0.01 to compensate for angular mounting offset in the position encoders. Back-up Time is maintained by a battery backed clock. Operating parameters, data and orbital models are held in EEPROM. Outputs Antenna drive. Emergency Stop contacts. Alarm contacts. Dimensions 483mm Wide x 132mm High x 406mm Deep. (19” rac

SPECIFICATION & OPTIONS INTRAC-305 OPTIONS A number of options are available for the INTRAC-305. The options are described in the following pages. Some of these options require changes to the firmware or hardware and some are only available when ordered at the time of initial order. Serial Interfaces only need a change to switch and / or connector positions within the INTRAC. Voltage The power supply unit (or units for Dual Redundant PSU option) of the INTRAC-305

2 INTRAC-305 SPECIFICATION & OPTIONS firmware change and required the EPROM on the interface card to be changed. Mount Type Two types of antenna mount may be used with the INTRAC. An Az/El mount or a Polar mount. The appropriate one is selected in “Fitted Options” as AZ/El or Hr-Ang/Declination. Resolver Type The INTRAC-305 is intended for use with standard Andrew resolvers, either x2 or x1 versions. Normally the INTRAC-305 is to replace an Andrew APC300 and the antenna

3 INTRAC-305 OPERATION 3. 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. FRONT PANEL EMERGENC

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. Dual Redundant Status Leds On Dual Redundant
