AIS Tester

AIS Tester handheld and lightweight

General description

AIS Tester is designed to check the Class A and Class B AIS mobile stations.

AIS Tester is a test device operating on AIS channel 1 (ch87B), AIS Channel 2 (ch88B) and DSC Channel 70 frequencies. The tester is designed under corresponding standards and recommendations ITU R M-1371-3 and IEC 61993-2 as a tool of operation and installation tests of AIS unit (Automatic Identification System).

AIS Tester M1 completely complies with new requirements set out in IMO Resolution MSC.308(88) under new regulation 18.9 to Chapter V of SOLAS which states:

"The automatic identification system (AIS) shall be subject to an annual test. The test shall be conducted by an approved surveyor or an approved testing or servicing facility. The test shall verify the correct programming of the ship static information, correct data exchange with connected sensors as well as verifying the radio performance by radio frequency measurement and on-air test using, e.g., a Vessel Traffic Service (VTS). A copy of the test report shall be retained on board the ship".

The tests volume complies with IMO circular letter “Guidelines on annual testing of the AIS unit MSC.1/Circ.1252”.

AIS Tester allows to test all type of AIS transponders of any manufacturer also it is capable to provide validation of operation of AIS-SARTs (Search and Rescue Transponders).

The AIS Tester is specified equipment for ship surveyors, classification societies and administrative authorities.

The test reports can be presented on the LCD display and stored in the memory accordingly with the facility of transferring them to a PC or laptop.

All measurements are carried out by means of cable and attenuator included in standard delivery set.

AIS Tester allows to check as terminal the pilot plug or external sensor.

Operation / Features

AIS Tester is user-friendly and easy to use test device.

During the tests the AIS Tester allows to:

  • Measure AIS frequencies (on channels 1, 2);
  • Measure or estimate the AIS transmitted power (on channels 1, 2);
  • Receive and decode the AIS messages;
  • Send the data to AIS stations;
  • Pass the DSC polling information (channel 70);
  • Check AIS answer to so called “virtual vessel”;
  • Simulate NMEA data transmissions.
  • Simulate AIS data transmissions, such as ship’s name, position, length, course, speed, power and beam.
  • Transmit and receive the DSC messages of different types for VHF stations;
  • Check the AIS-SART operation facilities;
  • Receive the data from pilot-plug or external sensors.

All data will be saved in memory for further processing, 10 memory blocks are available.

All data can be viewed on the tester’s LCD or can be transmitted to PC for procession.

The tester power supply is performed by 4 AA batteries 1,5V, as well as by external DC source with voltage 4,5…7V and load current no less than 500 mA.

Features:

  • Any AIS Class A and Class B station are supported;
  • Carrier frequency measurement in range of 156-162MHz within the accuracy  ± 99 Hz
  • Pilot plug and external sensors support;
  • Internal database of received data with possibility to save upto 10 test results;
  • Easy connection to PC, laptop, notebook to process the stored data;
  • Windows user friendly desktop application for database storage and review, process and test reports printout;
  • Long life batteries, easy replace;
  • Easy recalibration without returning back to factory;
  • 1year warranty.
AIS Tester connected to laptop

Connection to PC or laptop

After all tests are done usually it is required to process the measured data, prepare and print the test reports.

Thus the AIS tester can be easily connected to any PC or laptop. The connection is carried out by means of standard USB A-USB A cable and special software available on this website. The minimal requirements are Microsoft OS, such as Windows XP, Windows Vista or Windows 7 and at least 1 USB port. No special hardware configuration is required.

Also the special FTDI driver should be installed for proper connection. It can be downloaded at our web-site as well.

So, it is very simple to connect the tester to PC. Connect one side of the cable to tester and other to PC. Then install the drivers following the standard Windows wizard. After the driver is installed run the software. No installation is required. Just run the executive file and press DOWNLOAD MESSAGE button. All saved data will be transferred to PC.
