OVERVIEW

This document provides a basic overview of the operational use and applications of the AITS-R. It does not replace the AITS-R Operational and Technical manual in any way. The Operational and Technical Manual must be consulted for information and operation of the AITS-R. AIS Installation Test Set (AITS-R) Product Description and Features

AITS-R (AIS Installation Test Set) is an operational test set operating on AIS1, AIS2 and DSC (channel 70). An operational performance test is done on these channels, not actual frequency measurements. It has been designed in accordance with the relevant standards and recommendations as an aid to evaluate the operation of an AIS unit and AIS installation. The AITS-R is capable of generating and receiving AIS VDL & DSC messages. Radiated and conducted tests can be performed.

AITS-R is a hand held portable instrument with an internal battery pack and charging circuit. It can also operate using an external 12VDC supply.

AITS-R is menu driven, using a 2 X 16 character LCD display and keypad. All menu driven test options are fully automated. Test results can be viewed on the LCD display and can be stored in the AITS-Rs non-volatile memory. The AITS-R can store two separate test sessions, which can be downloaded to a PC at a later stage using the AITS-R utility software. Customized test reports in HTML can be printed.

Training is limited to the AITS-R software simulator and Operational and Technical manual, which is provided with the AITS-R. The AITS-R is field programmable and firmware upgradeable.

The LCD and Keypad are used as the man machine interface. The serial communication port provides electrical connectivity to a PC. The RS422 port allows testing NMEA strings of external sensor devices as well as selected items from the input/output stream of the Pilot or Presentation Port.

Two AIS radio receivers (AIS1 and AIS2) Digital Selective Calling radio receiver (DSC channel 70). A fixed frequency 2 mW nominal signal generator operating on AIS1, AIS2 and DSC (chnl. 70). An integrated termaline RF power meter and conducted interface (1 12.5W). A microprocessor with integrated DSP functions. In-line forward power and return loss measurement within a 26.6 millisecond transmission period In-line or antenna RF interrogation of AIS equipment under test using keypad, including DSC In-line or antenna RF decoding and display of AIS received packets, including DSC Fully portable with internal battery pack (rechargeable) & internal charging circuit LCD (2 x 16 character) display and keypad, menu driven command set Pilot / Presentation Port evaluation function (NMEA/RS422) Selectable non-volatile memory retains two (2) test session for processing Download test results to PC and print customized reports in HTML format Robust aluminium casing.

Quality Control The AITS-R has been tested and certified by ETECSA Services, an accredited test laboratory in accordance with the manufacturers AITS-R Operational Performance Verification Procedure, Document Number AITS-R/O/PVP/R1.1. Refer to Annexure C for a copy of the Certificate of Conformance. A copy of the verification procedure document is available on request. Each AITS-R is manufactured and tested in accordance with the manufacturers AITS-R Hardware Alignment and Performance Verification Procedure, Document Number AITS-R/H/APVP/R1.1. A product serial number and Performance Verification Certificate is issued. The values of the certificate are correct at the time of verification. Subsequently the accuracy will depend on such factors as the care exercised in the handling and use of the AITS-R and the frequency of use. Re-verification should be performed after a period that has been chosen to ensure that, under normal circumstance, the AITS-R accuracy remains within the desired limits. This period can be subject to the users quality policy, Classification Societys policy, etc. Refer to Annexure C for an example copy of a Performance Verification Certificate. A copy of the verification procedure document is available on request. A CE Certificate of Compliance is issued by the manufacturer with the supply of each AITS-R.
