NO fuzzy I think there's way too much technical talk and mostly by some who have absolutely no idea what they're talking about. But what you suspect is absolutely wrong. However I have no intention of spelling my background out specifically for these other jackals, my background is totally irrelvent but lets just say that what many find "fashionable" here has been a daily event for more years than I'd like to remember. Cheers, Kerry. I never get lost everybody keeps telling me where to go
  2. But in general these sites are a maze of myths and miscomceptions and in the past many similar myths and misconceptions have almost become fact, basically caused by some who had absolute no idea what they were on about. Trailblazer, there's many around here who also don't really know where your coming from, what for and why because on most days you make absolutely no sense what so ever. I can't put it any clearer than that, you mostly talk a whole heap of mumbo jumbo so if you want some advice drop all the riduluous claims and simply get to the point in plain simple english. Maybe you think talking the talk gives you some credibility (pinched that word from Jo) but in most cases it simply highlights a lacking. And yeah they're still using 1992 technology that should have been dead by 1998, so what just like they continue to use 12 year old GPS satellites that are 5 years past their use by date. So what, it's still old bloody technology, it's not hard to work that one out but you appear to think it's something new, get real. So what is it trailblazer a game to see who can post the most unrelated and out of date links. If you haven't realized things you post links for comment, so you get some comment then your complaining about comments, so what is do you want comment or not, if you don't want comment then why bother putting it up in the first place. Maybe Jo's gunna have to have a talk to you, your supposed to be hunting geocaches, benchmarks and bed bugs and you put up links of satellite imagery and remote sensing. Oh Jo won't be pleased. I'll call a spade a spade basically because I can and don't have any need to justify that. Cheers, Kerry. I never get lost everybody keeps telling me where to go
  3. Well fella's that simply tuff. You don't like it that's also simply tuff, you want to be smart arses then feel free. Perhaps you pair want to go back to the start of this thread and read it again. At least here some of the sh.. some of you go on with can be sorted out. Credibility, oh Jo you've got to be a complete joke. Cheers, Kerry. I never get lost everybody keeps telling me where to go
  4. You want a dead one or a live one? SVN5(PRN5) lost Nav (lost nav sounds better than saying it's dead, but it's dead) Nov 28, 1983, it lost its wheels . Was a poor performer only managing 3 odd years, now lost in space. Actually #'s fit real well with many things. Cheers, Kerry. I never get lost everybody keeps telling me where to go
  5. quote:Originally posted by Dave54:.... recreation grade GPS acceptable tolerance seems to be around 3-5 meters or so. 0.001 degree is roughly 2 meters so interpolation is acceptable and easy to do field math. A real nerd will whip out a scientific calculator and convert lat-long to UTM out to decimal point land, but most of us do not need nor care to for simple geocaching. Yes the calculator syndrome, Fix 9 decimals and we'll be spot on I'll assume then that the "0.001 degree" is a typo then 2 metres? is there another way to read that one, apart from what it's supposed to be? 309895 306319 4717676 4717008 Those 2 sets of numbers really have no typo similarlity at all. Cheers, Kerry. I never get lost everybody keeps telling me where to go
  6. Like I've said Jo, get stuffed, You wouldn't know a sock if you fell over one either. Generally the last line of defence for some who are really out of their depth is your type of faceless antics. I never get lost everybody keeps telling me where to go

  9. quote:Originally posted by jeff35080: quote:Not sure what the importance of this is, it's not that it's something new. Jeff .... If you don't understand that technology on a 1992 launched sea temperature satellite is a little outdated then like I said it ain't nothing new. Jason-1 ain't all that much different. Really the Turbo Rogue receiver is fairly common especially on some of the world's permanent recording sites. Because it's on a low orbit satellite doens't make it any special at all especially considering GPS has a service volume out to 3000km orbits anyway. Cheers, Kerry. I never get lost everybody keeps telling me where to go
  10. Well Jeff you obviously wouldn't know a sock puppet was if you fell over one. No, it might surprise that I do use my real name, how about that and you see I have no other reason not to and have used this name for obviously a lot longer around this site and past geocaching sites than you would remember. Some others do but you don't and the reason? I'll let you work on that one. You know Jeff after doing what you find "fashionable" and yes it's important for the past 30 odd plus years I probably place a much higher importance on BM's and all associated things than you'll ever likely to understand. You know your probably a fine Sherrif but don't give it away and become a detective as you'd make a lousy detective especially letting your fiction get in the way of the facts. Now you want to talk facts or continue with your sh.. Cheers, Kerry. I never get lost everybody keeps telling me where to go

You can go right ahead if you think you can "spane" it, you got something constructive to say then lets hear it. I'll make my judgement on what you say nothing else. Cheers, Kerry.

  13. So what, it's like saying that when Harrison invented the first "accurate" time piece that he was wrong as what was considered brillant in those years (early to mid 1700's) and realised as one of the most important "watches" ever made is not all that accurate in todays world. Of the 5 Harrison made he spent about 19 years solely dedicated to just one of them, for there was so much importance back then placed on conquering the longitude problem. With an accuracy of several minutes during a sea voyage they were considered revolutionary at the time. What's all this got to do with where ever this is going? well trailblazer you know times (literally) have changed, what was considered brillant in 1762 (and it was) can't hold a flame to the few nano seconds required today and as things get better then what else do you really expect, things have changed, things are going to change, methods have changed lets face it whole countries are constantly every single day and yet you have this thing about why have things changed. TB, you have some way to go in understanding that preciseness and accuracy of the GPS system has no direct realtionship to land ownership, occupation in any country. Flaws don't exist, just the thinking comes from a different point in time just like Harrison's clocks. Cheers, Kerry.

  14. I know one of these just have to ask questions but what is all the point in this and just where is it supposed to be going Cheers, Kerry. I never get lost everybody keeps telling me where to go
  15. Those UTM coordinates aren't even close and certainly nothing to do with any missing (m'). There's also a little misconception with this UTM, nearest metre and being more accurate stuff. One really has to look at the underlying coordinate system capability as ALL other precision capabilities will be based on that. Basically it's like being able to only measure to the nearest yard (3 feet) and thinking that one can enter things in feet and it's more precise. Similar reason why many receivers (even with M.mmm' precision) won't accept every metre especially in the latitude. Cheers, Kerry. I never get lost everybody keeps telling me where to go
  16. quote:Originally posted by DiscoverGPS:It's still out in the water, but at least it's in the ball park. I really thought it would be more accurate. So how blo.... far out in the water is it. How can anybody know just what is going on if all one gets is "it's still out in the Atlantic", now HOW FAR out in the Atlantic. Cheers, Kerry. I never get lost everybody keeps telling me where to go
  17. Unless some like going around in circles actually posting more relevent information would eliminate much of the guessing with a lot of this stuff. Many want some answers but trying to extract some of the information gets rather difficult at times. Really distances in this case mean nothing without the coordinates/location as then it's rather easy to determine if it is (or not) a datum issue or a format issue or both and if not then move on to some other cause. Cheers, Kerry. I never get lost everybody keeps telling me where to go
  18. At this type of receiver level the antenna differences really aren't going to make a great amount of difference when compared to multipath and other issues. Simply using an external and getting it a little higher will help as it can eliminate the user as an additional unwanted obstruction. Having a good lock first also helps but in essence one works in the woods knowing that things really aren't supposed to work, so many variables. Cheers, Kerry. I never get lost everybody keeps telling me where to go
  19. The first 2 actually did have names SVN#1 was Elvis and SVN#2 was Janis then things simply went SVN3(PRN6), SVN4(PRN8), SVN5(PRN5) etc etc rather dull but the numbers have it. By the way both SVN1 & 2 have passed on. Cheers, Kerry. I never get lost everybody keeps telling me where to go
  20. Alan2, the coordinates as written one could assume that but the numbers do match the orig DM.m positions but of course that's not the way they are written here. What was meant and what was used, who knows but gradually we'll pick away at the information that might put some light on the possibilities. The most position format differences between DM.m and DMS will throw things is about 1/2 a mile. The Atlantic ocean is a big place, just need to now which bit and how far. Cheers, Kerry. I never get lost everybody keeps telling me where to go
  21. A good test procedure is always subjective and not simply an ovservation as with GPS being dynamic, conditions as you will understand are constantly changing. Just because one has reception at a particular time in a particular place simply doesn't mean that will always occur. As with any testing visual observations can be very selective as opposed to actually recording the data and using ALL the data over a specificed time frame. I suppose the thing is that since conditions can never really be duplicated then it's difficult comparing this indoors reception issue as really there is simply no consistency. It's really not a comparison that one can base any judgement or decision on as far as single individual receivers are concerned. This whole inconsistent issue of indoor reception is what defeats the 911 requirement in mobiles. Cheers, Kerry. I never get lost everybody keeps telling me where to go
  22. So how far out into the Atlantic is it? Knowing that might help to determine what type of issue it is. Cheers, Kerry. I never get lost everybody keeps telling me where to go
  23. That difference has all the markings of a possible datum and/or position format issue. You were asked about the datum but haven't mentioned looking at that so validate both datum and position format are correct. Eliminate the simply things first. Cheers, Kerry. I never get lost everybody keeps telling me where to go
  24. There's nothing wrong with those coordinates so it suggests the problem is at your end. But without being a mind reader it's difficult knowing exactly what your doing in Mapsource. Cheers, Kerry. I never get lost everybody keeps telling me where to go
  25. Sometimes one really needs to sort out some of the myths and misconceptions about this reciever or that receiver and sometimes even sort out why there are these "perceived" differences. So one receiver locks faster then another in "most" conditions. So what are these conditions and just what is the time differnce? "In a hallway/vestibule entrance to my office building, the Sportrak maintains better sat reception" if anybody is actually expecting this and thinks it's a attribute then they need to read the specifications. "In my backpack, the Legend tends to maintain better lock" like if it's really relevent! again relate this to the actual specifications. "The Legend will show breaks in tracks when sat lock is lost, while the Sportrak throws in extra tracks to connect the lost track points ..." and so they bloody well should, a lost signal is a lost signal and anything that wants to start interpolating is making assumtions, and that's not acceptable. "Under tree cover it seems a wash as both seem to lose around the same amount of time" and so they should. When some realize what the overall controlling factor is then these types of comments simply won't exist. I've also really never come to terms with how some companies can state accuracy fiquires that are better than what the "actual" system specifies. Sometimes one really has to wonder if all this is simply manufacturer PR crap. Cheers, Kerry. I never get lost everybody keeps telling me where to go
