6. DATA REPORT AND POLLING
This chapter provides the information necessary for data reporting and polling recep-
tion. Data reporting provides automatic data transmission at regular intervals from
your ship to your home office. When your ship receives a polling command from your
home office; that is, a request for navigation data from your ship, it automatically trans-
mits this data to your home office.
No operator intervention is required during polling reception.
6.1 Data Reporting
Data reporting provides automatic data transmission at predetermined intervals from
your ship to your home office. The data are position, speed, bearing and other data
sent from a navigator or an interface unit.
The data transmitted from the FELCOM is temporarily stored in a data reporting file at
the LES. When an operator at your home office accesses the LES, the LES delivers
the data to your home office. Some LESs may deliver it without being accessed.
Data reporting can be initiated by setting a data report on the FELCOM or receiving a
polling command from your home office.
This FELCOM offers two types of reports:
• Data report (on MES signaling channel). See section 6.1.1.
• Message report (on MES message channel). See section 6.1.2.
