Ping Rate????

Postby Ramius-II » Sat Nov 24, 2012 5:14 pm

Hi All! :D
Just a quick question about when a sub does pings.
How often does a sub send out a ping? 3 seconds, 5 seconds, more, less?
Inquiring minds wish to know! :wink:

Thanks, Ed
Just one more wire!

I have no idea about real sonars, but the limits are that they will probably expect to ping up to a kilometer.
that means 2000 meters of travel, which means you hear the echo in 2000/1500 seconds, as sound moves
roughly 1500 meters a second in seawater.
so the minimum time between pings would be just over a second.

however, pings will take a time to transmit and range might be larger.
Which means longer periods inbetween pings.

so, one second seems to be the minimum time between pings.

I expect *real* submariners do not use active pings. it's unhealthy ;-)
