KM... 954 Posted January 1 Share Posted January 1 Using a Garmin GPS76S I brought gawd knows how long ago, to map some plantings and it's been going fine. But this arvo I booted it up and it initialised but just sat on 'searching for satellites'. It does that always but only for maybe 30 seconds max if I last used it a long time or distance ago. Does anyone know if there is some GPS to Jan 1st 2021 connection that we may have run into? Quote Link to post Share on other sites
Steve Pope 138 Posted January 1 Share Posted January 1 I just fired my 60CX up, it has come on line but says weak GPS signal which it has never done before? Quote Link to post Share on other sites
CarpeDiem 37 Posted January 1 Share Posted January 1 What software version? You may need to upgrade... Try setting a New Location using automatic it's in the Satellite menu iirc. You will need to wait a while cause it will need to receive a new almanac. This could take 60 minutes. Quote Link to post Share on other sites
L00seM00se 39 Posted January 1 Share Posted January 1 I have an old GPS12 unit. It can take up to 5 minutes to acquire if it’s been off for more than 30 days. Same with my Garmin watch. Quote Link to post Share on other sites
Deep Purple 289 Posted January 1 Share Posted January 1 The backup battery in my fizz boats simrad chart plotter has failed and every time I turn it on have to manually enter the depth transducer settings and approximate position, it takes 5-10 minutes to require position. If I don't enter the approximate position it takes much longer. Unit is probably 15 years old Doesn't save waypoints either. Waiting for boat-show special to replace it, sadly none of them happened last year Quote Link to post Share on other sites

Show specials, are they really on special??brought maxxon a few yrs ago, boat show special was $1399 from memory brought from their shop (smart marine)$1150 10ft Quote Link to post Share on other sites

KM... 954 Posted January 2 Author Share Posted January 2 A great selection, as always Thanks team. So I thought power but bars showed fine. I thought Hmmmm... and so took 1 (AA of 4) out and shuffled them all back in, bars shows they had gone off. New batteries in and booted up fine but stuck again. 5 or so minutes later I put it down and forgot about it, when I came back it was working sweet. Turned it off, waited 10min, turned it on and acquired enough Sats to pin us down inside 15 seconds odd. It is fast if it's booted in the same place it was turned off or there abouts. So no idea what happened and as i have to climb a hill to get reception bugger searching until we're better placed. I'll also suss for updates. Quote Link to post Share on other sites

It's good for about two weeks. The GPS constellation transmits bits of the Almanac every 15 minutes of so. This Almanac tells the reciever where the Satellites are. When I say GPS I specifically mean the USAs satellite constellation. Not other nations constellations that a more current receiver can use. Advances in receiver processing power has made the Almanac unnecessary in latest devices. 1 Quote Link to post Share on other sites

idlerboat 84 Posted January 4 Share Posted January 4 Why wouldn't you just use your phone ? !! If it is a newer version it will be running up to 4 different countries satellite navigation systems. ( GPS is the American one ) For land based stuff the not so humble phone is way more powerful than any stand alone GPS. ...and all the maps ( they're not charts) are free , (And no.. you don't need to be in range of a tower) Quote Link to post Share on other sites

The screen tried to change to black with only green lettering due to the units age but we pushed on. Looks like you were spot on the money fella, nice work. I was a few updates out of date and it needed a general refresh. I notice now it can see 10 Sats at once, until now it's maxed out at 8.

KM... 954 Posted January 11 Author Share Posted January 11 I have sussed many options, a methane generator being one. They take a fair bit of feeding and we won't have enough to do that, we will only have maybe 35-40 beefs maximum, bloody flash ones the Wa will pamper more then her kids I'd expect. Also sussed micro pumped hydro storage/power but still working thru the efficiencies or not of the pumping angle, that could take a lot of the power it generates which is sort of OK for water transfer and storage for the trees to drink but as power generation maybe not so much. So at the moment solar and wind coming as soon as they can get to us. But I am building a solar tracker for the stage 1 panels. That is expected to increase the power output of the panels about 40-50% per day on average over a year. I did a wee experiment over this break on having the panels static then 'track the sun'. When the sun came up the panels were set square on to it then every 2-3 hrs they were reset to be square again right up until 7:30pm was the last reset to capture that last hour before sunset. While at sparrows fart and days end they don't put much into storage they do get/keep the voltage up so they reach storage inflow a lot faster or delay storage outflow. The output with tracking over set and forget was huge and very very obvious. We reckon when there was overcast, that lighter sort of stuff, it made the difference even bigger. So I can see times when tracking could double the output per day. Add a 1000W windmill and we should be more than good to go once Stage 2 of the PV's are in, which will take us a bit over 6kW all up. We are also planning on rivalling Tesla in the amount of battery storage we'll have Carbon Lead looks like the path we'll be heading down for those. Quote Link to post Share on other sites
