Screenshot, Lowrance SI...
Lowrance Side Viewing!!! No Rumor: Sonar/GPS Installation & Operation: BBC Boards
Just a comment of my own...do you find it ironic that HB comes out with a software update for their 2d long about the time that Lowrance offers SI. Given the fact IF Lowrance SI has the same or nearly the same quality and functionality that the HB SI offers, it only stands to reason that they would make an attempt to clean up their 2d image. Could be a coincidence :rolleyes:.
Gotta love competition...good for the consumer!
5 Hz GPS refresh.......JAX
"For extra precision, it offers 5 Hz Measurement Pulse Output with rising edges that align to precise 0.2 second increments of UTC time, as long as the receiver has reported a valid and accurate position during the past 4 seconds".
This information is from a GPS chip set that has the 5 HZ refresh capability.
What this is basically saying is that the 5 hz refresh is a calculated guess based on received position from the GPS satellites and a digital clock internal to the gps receiver, not the satellite signal coming 5 times a second.. I believe this technique is used in agriculture and surveying.
I do not know much about this as there is not much info on the net yet.
Everyone is tight lipped about this stuff.
