LEELEE Posted March 1, 2005 Share Posted March 1, 2005 With my new sounder i decided to punch in some GPS cords for my trip away. I have now stumbled accross a problem, but i think its more closer to the fact that i'm stupid than any thing else. I have no problems entering the gps cords as follows - 28.35.052 S 153.38.283 E, but how do i enter in the following cords - 32.45.03 S 152.12.56 E The seconds are only 2 digits in the second mark and 3 digits in the first. How do I enter them in with only 2 digits in the seconds part of the mark. Cheers Lee Link to comment Share on other sites More sharing options...
clutch Posted March 1, 2005 Share Posted March 1, 2005 Lee, I'm probably the last one to be giving advice on this but cant yiou just add a zero to the seconds. Link to comment Share on other sites More sharing options...
LEELEE Posted March 1, 2005 Author Share Posted March 1, 2005 Hi Clutch, I thought about that but wher do I add the zero to. To the start of the seconds or the end. I'm really confussed, but i think you are right on the money with that idea. Thanks Cheers Lee Link to comment Share on other sites More sharing options...

Guest Jocool Posted March 1, 2005 Share Posted March 1, 2005 I'm just as stupid as you are with GPS...But are you entering it in the right datum...or format?? Link to comment Share on other sites More sharing options...
tyrone07 Posted March 1, 2005 Share Posted March 1, 2005 My dads more of an expert on gps but go into settings and it will say something like deg.m.mmm is wat urs is set on and you have to set in to deg.min.sec. Im pretty sure tell me what things you can change it to and ill try tell u. Id get dad to to help but his away. Link to comment Share on other sites More sharing options...
clutch Posted March 1, 2005 Share Posted March 1, 2005 That last digit is really fine tuning and swinging around on your anchor can probably nullify that thousandth of a second Link to comment Share on other sites More sharing options...
LEELEE Posted March 1, 2005 Author Share Posted March 1, 2005 I have a navman 5500i and as far as i can see i can't change the settings from deg.m.mmm to deg.min.sec. the map datum is setup as WGS84. Does that need to be changed. Man i'm dumb. Cheers Lee Link to comment Share on other sites More sharing options...
tyrone07 Posted March 1, 2005 Share Posted March 1, 2005 i dont know nuthing about map datum. thats all dads things he plays with. weve got navman color sounder the biggest one and its awesome. ill look into it for you lee with the co ordinates.

clutch Posted March 1, 2005 Share Posted March 1, 2005 Dont change that WGS84 Lee. Thats the default and usually correct according to the manual http://www.vmraq.org.au/docs/184.pdf#searc...r%20manual' Clutch Link to comment Share on other sites More sharing options...
LEELEE Posted March 1, 2005 Author Share Posted March 1, 2005 No worries. I was not going to change it, but thought it might be an issue. Still not sure how to make sure that adding the zero on the end is the correct way. Cheers Lee Link to comment Share on other sites More sharing options...
pogo Posted March 1, 2005 Share Posted March 1, 2005 As far as I Know using the Zero will work just fine. I use gps all the time at work and the last three or two digits are seconds of a degree. As in 0 to 90 N and S, 0 to 180 E and West degrees each degree is made up of 60 minutes and 1 minute is equal to 1 Nautical Mile at the equator and also N/S Each minute is divided into 60 seconds. 1 Nautical Mile equal to 6080 feet So 1 second equals about 100 ft and the third digit of the seconds is 3/8th of 1/4 of the proverbial. Probably less than the wander. It is important if your setting up an inertial Nav system but for a fishing spot you'll be within a couple of boat lengths Regards POGO Link to comment Share on other sites More sharing options...
LEELEE Posted March 1, 2005 Author Share Posted March 1, 2005 Cheers guys. I have checked the gps marks I have and compared them to my c - map and most of the marks are way out. Probably dodgy way points i'm gathering. Cheers to all that helped. Lee Link to comment Share on other sites More sharing options...
Guest Big-Banana Posted March 1, 2005 Share Posted March 1, 2005 Different Datum. We have a fairly new Raymarine GPS and out mate who we follow out to the traps has an old Garmin. His marks are all a digit shorter. I think its just for pinpoint accuracy. But if you go into Bias just ask them. Link to comment Share on other sites More sharing options...
shecomb Posted April 11, 2005 Share Posted April 11, 2005 Sorry for digging up old posts but there should be an option in the menu to change the coordinates configuration with an option like what you need. This should fix your problem. -Dave Link to comment Share on other sites More sharing options...
REKLESS Posted April 12, 2005 Share Posted April 12, 2005 I think that Ian has it right about the two different versions.I might also point out that when you start getting within two decimal places of looking for a spot you are generally using the sounder to eyeball it. Anyway,drift,tide ,wind and sea conditions will more often then not have you swinging over your spot as long as mr anchor is in the right spot. simon Link to comment Share on other sites More sharing options...
dirty earl Posted April 12, 2005 Share Posted April 12, 2005 Leelee, Just add a zero (0) after the second number... for example: 32.45.03 S becomes 32.45.030S 152.12.56E becomes 152.12.560E Cheers, dirty earl With my new sounder i decided to punch in some GPS cords for my trip away. I have now stumbled accross a problem, but i think its more closer to the fact that i'm stupid than any thing else.I have no problems entering the gps cords as follows - 28.35.052 S 153.38.283 E, but how do i enter in the following cords - 32.45.03 S 152.12.56 E The seconds are only 2 digits in the second mark and 3 digits in the first.

clutch Posted April 13, 2005 Share Posted April 13, 2005 Heres a read http://www.paddles.com/users/wildcamp/coordexp.html Iains onto something Although if you look at the original post are you sure there not just missing a thousandth decimal?

shecomb Posted April 13, 2005 Share Posted April 13, 2005 I disagree Earl!Adding a zero does not convert DD.MM.SS to DD.MM.MMM You must convert the minutes to a decimal by diving the seconds by 60. Please correct me if I'm wrong! 42211[/snapback] I agree with you iain. minutes is in 100ths and seconds is in 60ths. The conversion must divide into 60 like you said. Even so, the actual difference in position couldn't be much more than a couple of boat lengths Link to comment Share on other sites More sharing options...
