Legend
| 0 | MCC has requested that no additional alert messages for a particular beacon activation be sent to it after a message has been received that includes a confirmed position for that beacon. |
| 999 | MCC has requested to receive unlimited additional alert messages for a particular beacon activation even after receiving a confirmed beacon position. |
| [xx] | The number specifies the maximum number of additional alert messages desired by the MCC after receiving a confirmed position from a particular beacon activation. |
Notes:
(1) Maximum Number of Alerts Requested after Position Confirmation:
- All MCCs by default will receive continued transmission of MEOSAR data for a beacon, even after initial position confirmation (and will be shown as 999 above) unless the MCC has notified its nodal MCC and the Secretariat of a preferred numerical limit to messages after initial confirmation of a beacon’s position.
- Per document C/S A.001 section 3.2.5, the capability to limit the number of alerts after position confirmation is not required.
(2) For current operational status of MCCs, see the Cospas-Sarsat Quality Monitoring System (QMS) tables.
The following status information is provided from the EWG/JC formal recommendation when:
(3) the MCC is commissioned for FGB ELT(DT) capability.
(4) the MCC is commissioned for SGB capability (including SGB ELT(DT)).
* Since CSC-69 in 2023, new DMCCs shall be commissioned at the same time for the three following capabilities: MEOSAR IOC/FOC, FGB and SGB ELT(DT), and SGB.
** Capability commissioned but not declared as “FOC” due to nodal MCC restrictions.
