Wow! thank you, I have one of these I picked up at a garage sale. I messed around a bit but it never seemed to work quite right. I'll give it another go.
Cool! I fully admit that I had no idea how long the cold start up would take. I was assuming that it would be maybe 10 minutes or a bit more. I'd almost given up when it locked onto one satellite and so then was able to start locating itself.
I used a big, military, vehicle-mounted ("handheld" was i misnomer) in Bosnia back in 1998. It took forever to start, and after my car had been parked in the same spot for about a week, it was barely able to tell the correct altitude. I just "inherited" this model (software dated 1997), and while it works fine with fresh batteries, its age certainly shows when it comes to acquiring satellites. Modern devices can have a hard time finding satellites if they're in a moving car when you turn them on, but this one really requires patience on the part of the user 😀
Right. I expect the tech of the one you used in the military was similar to the civilian in my video, but at that point it was probably 10 years old and not very miniaturized. That's why I wanted to make this video. Modern units have multichannel receivers, so they're doing the same process if they're turned on after months of being off, but it's much faster because they can be listening to 6 or 8 or more satellite frequencies at a time. Most of the time, you don't even notice the lock-on sequence because it's done before the device's own normal startup screens. The GPS receivers in my Mooney are like that. You can see that in my recent "cold and dark startup" video. Both GPSs just fire right up and don't spend any time at all on the "searching for satellite" screens. At that point the plane had been outside and powered up only a week or two before so its internal data was fairly fresh. I have had to wait in the airplane for "searching for satellites" a couple of times, like when I got my ADS-B transponder installed, and the plane was inside and off for several weeks. Thanks for commenting! Please feel free to check out the other videos on my channel. I have videos on the VW restoration project I've been working on, some flying videos, and some other tech videos like this.
I got an old Eagle explorer, it says 12 chanel receiver on it... but I also doubt that it is capable of listening to 12 satellites at the same time... I tried a cold start, could get two sats after 10 minutes locked on and eventually got bored and tiered, and turned that off. will let it sit tomorrow outside for longer and see how this goes.
Yeah, now that it has a current almanac it might have a better chance. As it builds up information it gets faster at acquiring satellites, because it knows which ones to hunt for specifically.
I was just given a Garmin GPS 3 plus and It’s cool to see it working properly but it doesn’t give me a proper date it says September 3 2003 for the date and isn’t the right time but it knows where I’m at 😂😂😂😂 it makes me a bit sad the AA compartment is all corroded so I can’t power it by it’s self out of my car to see if it’ll update properly 😂
Hmm. It's possible that there's a firmware update that could fix that. It's possible that there was a minor update to the GPS protocol from the satellites that is confusing it. I'd do some Google search. Update the firmware VERY CAREFULLY. Those old-school serial connections don't have a lot of error handling built into them. If the connection goes down during the update, it might bring the GPS completely. Only do it with a stable computer that you trust that isn't running a lot of crap. Don't be running a bunch of browser tabs while it's updating; in fact, don't have your browser open at all. Good luck with it! That sounds fun! Sorry it got corroded.
