soon be 50 such satellites.!
At the present time, you may have to wait between 30!
minutes to 1-1/2 hours to determine your position!
depending on which latitude you are travelling.!
Soon, when all the satellites are in orbit, you will be!
able to pinpoint your location anytime day or night.!
Note that Satnav does not relieve you of the!
obligation to carry a sextant on board and to know how to!
use it. If your Satnav ceases to function for some!
reasons, you will have no choice but to use your sextant.!
Even if you have a Satnav, practice often with your!
sextant.!
g) OTHERS!
In our opinion, it is necessary to have on board a!
knot meter and a log. It is also very convenient to have!
a unit which will indicate wind speed and direction. A!
depth sounder is mandatory.!
