the identified sentence to be output.
NOTE 2 Sentence formatters shown in shaded rows are described in IEC 61162-1.

5.3 Minimum requirements for the TDMA transmitter of the AIS Base Station
Replace the existing Table 5 by the following new Table 5:
Table 5 – Minimum required TDMA transmitter characteristics
Transmitter parameters 25 kHz channels 12,5 kHz channels
Carrier power error
± 1,5 dB ± 1,5 dB
Carrier frequency error ± 500 Hz ± 500 Hz
Spectrum mask for slotted transmissions

–70 dBc at ± 25 kHz –60 dBc at ± 12,5 kHz
Transmitter test sequence and modulation accuracy ‘0’ bit start for test signals 1 ‘0’ bit start for test
and 2 signals 1 and 2

signal 2 test signal 2
Transmitter output power versus time Power within mask shown in Not applicable
Figure 11 and timings given
in Table 12
Intermodulation attenuation ≥ 40 dB Not applicable

6.2.1 General rules
Replace the eleventh bullet and text by the following:
• when the UTC sync source is unavailable, the AIS Base Station shall use UTC indirect or
shall be synchronised to another Base Station;

6.3.1 General rules
Replace the third bullet and text by the following:
• when the UTC sync source is unavailable, the independent AIS Base Station shall use
UTC indirect or the semaphore rules as defined by ITU-R M.1371;
Add, after the last bullet and text, the following:
• all VDL messages shall be as short as possible.

6.3.4.8 AIS Base Station response to VDM input
Add, after the second paragraph, the following new text:

62320-1 Amend. 1 © IEC:2008(E) – 5 –
A transmission initiated by a VDM input shall not replace a scheduled message.
Messages 4, 11 and 20 shall not be transmitted.
Messages 15 and 16 shall not be transmitted if a slot offset is provided unless the slot offset
is recalculated by the base station. Messages that have a Comm.state shall have the
Synch.state bits of the Comm.state set to the current status of the station. The remaining
Comm.state bits shall be set to zero to prevent false slot allocations.
The repeat indicator shall be set to greater than zero before transmitting.
After receiving a VDM sentence, the Base Station responds with the appropriate TFR
sentence.
6.3.5 Autonomous channel management
Add the following text as a new second paragraph:
The “in use” data field of the ACA sentence defines the status of the region (0 = not in use,
1 = in use). The manufacturer shall declare the number of regions supported.

6.4 BIIT conditions
Replace the existing text by the following text:
The AIS Base Station shall monitor the following BIIT conditions and shall generate the
appropriate ALR sentences on the PI. The ALR sentence shall be output at least once per
minute. The alarm conditions are noted in Table 9 and the resulting alarm status is sent via PI
sentence ADS. If an alarm is active (acknowledged or not), the ADS alarm status field is set
to A; if no alarm is active the field is set to V.

6.5.3 DGNSS dedicated port option
Replace the existing text by the following:
The AIS Base Station may be configured to transmit DGNSS corrections (Message 17) that
are input via a dedicated RTCM SC104 format DGNSS port.
Base Stations shall convert the RTCM SC104 format to VDL format before transmission.
This option shall only be available for the independent operation and care should be taken to
minimise the impact on the VDL.

8.1.4.1 Standard test signal number 1
Replace the existing text by the following text:
For TDMA Type 1: A test signal consisting of a 26 ms packet (1 slot) of 010101.

– 6 – 62320-1 Amend. 1 © IEC:2008(E)

8.1.4.2 Standard test signal number 2

measurement
Replace the existing item b) by the following new item b):
b) The wanted signal, provided by generator A, shall be at 162,025 MHz and shall be
modulated with a 1 kHz sine wave at ±2,4 kHz deviation.

measurement
