CTN Test requirement Acceptance criteria
Procedure
EL1 The equipment is activated into the ASP system CSP acknowledgement received
ASP issuance of an activation command (Note: this function is critical during the transfer of flag process)
1 Establish the sea areas the ship is certified to operate from the Cargo Ship Safety Radio Certificate, Cargo Ship Safety Certificate, Passenger Ship Safety Certificate or equivalent Confirmed by shipowner declaration on testing registration form prior to testing including certificate type and reference number
Administrative
2 The equipment automatically transmits an LRIT information Validated in conjunction with CTN 9

Evaluative
4a The latitude and longitude is present in the received LRIT information Validated in conjunction with CTN 9
Evaluative
4b The equipment GNSS position information is based upon the WGS84 datum Assumed compliant in accordance with standard IMO guidelines and regulations
Evaluative
5a The date and time is present in the received LRIT information Validated in conjunction with CTN 9
Evaluative
5b The equipment date and time information is in UTC Confirmed by the ASP recognized by the Administration or approved to conduct conformance testing based upon the confirmed inclusion of MEM code 11 (in the case of Inmarsat-C) and in the case of alternate hardware the compliance of the received message structure with the equipment manufacturers published standard for a message containing the generated Date and Time stamp
Evaluative
5c The equipment transmits a Time Stamp relative to when the position was generated (not the CSP receipt time) Confirmed by the ASP recognized by the Administration or approved to conduct conformance testing based upon the confirmed inclusion of MEM code 11 (in the case of Inmarsat-C) and in the case of alternate hardware the compliance of the received message structure with the equipment manufacturers published standard for a message containing the generated Date and Time stamp
Evaluative
6 The equipment is of a type approved by the Administration Forms the subject of this test specification which will be if the results are satisfactory and a Statement of conformity is issued by the ASP conducting the test (and the subsequent issuance of a Certificate of compliance by the Administration)
Administrative
7 The equipment is switched off on board or ceases the distribution of LRIT information CSP acknowledgement received and nil LRIT information are transmitted within 90 min
ASP outbound Program-Stop command
8 The equipment is compliant with provisions of resolution A.694(17) Confirmed by manufacturer or validation of technical specification
The equipment has been tested for electromagnetic compatibility (refer to resolution A.813(19))
Administrative
9a The equipment is re-configured to automatically transmit LRIT information at 15-min intervals Confirmed subsequent to receipt of 48 consecutive 15-min automatic transmissions of LRIT information. Refer to paragraph 3.2 for information on acceptable tolerances.
ASP issuance of Start-15 min reporting command
9b The equipment is re-configured to automatically transmit LRIT information at 60-min intervals demonstrating that a change in transmitting interval has been successfully achieved Confirmed subsequent to receipt of 12 consecutive 60-min automatic transmissions of LRIT information. Refer to paragraph 3.2 for information on acceptable tolerances.
ASP issuance of Start-60 min reporting command
9c The equipment automatically transmits a LRIT information at 6-h intervals Confirmed by ASP or manufacturer or validation of the technical specification
Administrative
9d The equipment is re-configured to automatically transmit LRIT information at 24 h intervals Confirmed by ASP or manufacturer or validation of technical specification
Administrative
9e LRIT information is available within 15 min of the time it is transmitted by the ship Validated in conjunction with CTN 9a and 9b
Comparison of the UTC time stamp when the LRIT information was generated against the UTC time stamp when the information was received by the ASP
10 The equipment transmits LRIT information (subsequent to the ASP issuing a poll command) and the LRIT information is available within 30 min of the time the ASP has requested the information Confirmed subsequent to receipt of 1 polled transmission of LRIT information within 30 min
ASP issuance of a Send-Request for Position command
11 The equipment interfaces directly to the shipborne global navigation satellite system equipment, or has internal positioning capability Confirmed by ASP or manufacturer or by validation of technical specification if internal GPS, or if external GPS confirmed by shipowner declaration on testing registration form prior to testing
Administrative
12 The equipment is supplied with energy from the main and emergency source of electrical power (this provision does not apply to Inmarsat-C) Confirmed by shipowner declaration on testing registration form prior to testing
Administrative
13 The equipment automatically transmits LRIT information via the CSP to the ASP in a reliable and secure manner Confirmed by the ASP recognized by the Administration or approved to conduct conformance testing based upon confirmation that all communication links from the terminal – satellite – CSP –ASP are direct and secure with no third party ASP involvement
Administrative
EL2 The equipment is de-activated and released from the LRIT system CSP acknowledgement or CSP declaration received
ASP issuance of deactivation command or Administrative (Note: this function is critical during the transfer of flag process)
