How Does NAVTEX Work?
NAVTEX transmissions are sent from stations situated worldwide. The
power of each transmission is regulated to avoid the possibility of
interference between transmitters. Each station is allocated a 10-minute
time slot every 4 hours so that many stations can share the same
frequency. Stations typically have a transmission range of 250 – 300
Nm.
