It's estimated that if all the pension funds who have invested billions in oil futures walked away we would see a $20 drop in the barrel price of crude. Regarding sailboats, if a 50hp motor can push a 37ft sailboat it can push a 37ft trawler. My 30', 5 ton, soft chined full displacement trawler has a 40hp diesel that averages 3/4 of a gallon an hour.

I'd estimate that we've anchored perhaps 200 times with the unit from Florida to Venezuela to Maine to the Mediterranean and it has not malfunctioned yet. I'm not sure what you mean by remote control, but mine is installed in the pilothouse, though the windlass can be operated from either the foredeck or the pilothouse.

Menu - Navigation - Satellite Status - EST - and entering the estimated present Lat & Long it then asks for Ant Height, the UTC date and Time. When I enter the date i.e. 080821 (Aug 21 2008) it immediately reverts to back to 890106 (Jan 06, 1989). The last digit, the day, will increment at UTC midnight.

Estimating how much salt to add to prevent damage to the electrode packs is a tricky business and Raritan obviously came to the conclusion that a major improvement was needed, the new control unit is the answer.

Or you can just estimate the decimal portion of the minutes once you've done the multiplication times 60.

I estimate I would be able to "see" about 200 feet...  my main use/concern is to look for/avoiding crab pots in the Florida gulf coast.  Also do not want to destroy my nite vision with a huge conventional spot light.. Too cheap to buy one of the hand held nite vision devises... I figure I could build it for less than $300... Anyone done this?

I am not expert on this but I estimated that the method we are discussing is O(n^3). The valid_ears() search is O(n^2), due to two nested for loops. The recursive triangulation has depth n and call valid_ears() once for each found triangle.

In the meantime, a combination of estimating the RTT of a control packet and using the incoming RX timestamps to gauge when to send the re-tune packet; that may be your best option. If you are looking to re-tune as fast as possible, I recommend re-tuning the DSP/cordic only, which gives you about 40Mhz of bandwidth to frequency hop with.

The GPS satellite signals are used to provide estimates of timing slip between the on-board clock and the satellites. Assuming that the on-board clock on the GPSDO has recently been "in synch", it will slowly drift out-of-synch according to it's "natural" proclivities as a piezoelectric crystal oscillator of reasonably high quality.

However, I noticed that the phase difference (~0.4 usec) is constant for all runs and I was able to estimate it in MATLAB (using recorded signals), but aren't they supposed to be aligned? Where does this difference come from?
