playing with all this high tech stuff and I'm leary of trying to upgrade the map system in my truck. Looks like they make it easy but
There is an incredible amount of data involved with the GPS and GNS/GLOS
plus three more, at least systems. They have been improving both the military and civilian systems continuously since the 60's. Since 2013 The Air Force has upgraded with a new generation that improved the capabilities proly 10 fold. Now when you consider that technology is 20 - 25 years old already and it wasn't placed in service until 2022. Imagine what they must have now!!!
A good thing is all of the other systems Soviet Union's European and Asian are being combined adding that many more points of reference to the system making it even more accurate. Some are accurate and others are ignored completely.
Along with the satellite systems are the ground waves or horizontal data streams that come from cell phone radio waves, Internet feds, hosts and independent signals/servers. They are not distorted like the satellites due to the Ionosphere, magnetic and weather affects. There is a giant industry now created to cater to the needs of the auto industry, cell phones, civil clients such as police and fire services. One of the fields makes use of cloud services and the IoT
(Internet of Things) market. What they do is relay data streams from a company who provides correcting data and it's then broadcast thru WiFi to customers who need it for their GPS devices such as automotive.
The manufacturer of the chip I purchased for my GPS gadget is based in Switzerland and are a world leader in the field. They now own one of those types of services and offer it world wide. The prices start at $3.98 a month and go up from there into the hundreds of $$$.
They caused me to think that I needed their service since they gave a trial membership with the purchase of the chip. I wound up not using any of it after two days of trying out several software programs that needed to work together having a windows 3 type program in the middle.
Once I realized how far off track it had become and the reason I purchased the chips to begin with was for that exact reason, the two chips work together and eliminate the need for an outside service offering corrective data. One chip receives the corrected data from certain satellites then translates it and feeds it directly to the other chip that makes the final adjustments. They don't offer support for this product other than the mixed up complicated user interface they advertise as their free software which is now four or five years old. It's clunky much like a terminal program.
I think they realized they were giving away for free the item they are trying to sell with the pay per month service.
That's fine and for those of us who were lucky enough to have purchased these chips, we can make good use of them. They advertise them as not for use by the general public and are for industrial use in developing products that are similar.
I've learned how to work with the chip using programs from simple C++ compilers to the latest Microsoft Visual Basic release. With the additions to the core program it's now over 10 gig!!! How about that for bloatware!!!
They seem to have made their free software as daunting as possible, as an example, once booted up, from the ROM base line instruction, the Bios which relays the operating system to flash memory that is written to RAM, the random access memory which tells the hardware, the chips how they are supposed to act, the first thing that happens when the chip connects to the comport that connects the Free software interface , it downloads 6,500 lines of text, listing every possible type of information the satellites can send and whether or not they have connected with each one of them. Then it will continue to download the information once every second. I'll give them a little bit of credit in that it is not a steady stream like a garden hose turned on full blast, it only corrects each line with the information that has changed. It might be a no that changed to a yes or a one that is now a zero.
All of the default settings, at least the ones that show can be changed such as changing the one second poll to five or six. Satellites can be completely eliminated but I need to be very careful, I do not want to write it to bios so i will simply write it to RAM with a script at first then if I like the results write it to flash where it can stay so I will only need for the script to run one time .
Piece of cake!! š°
Just not a cake with frosting on top. LOL!!! š„®
I was able to download a copy of the last firmware so I would be able to re-flash the bios/ROM If needed and they say the flash and RAM can last a million write cycles. It's funny how after posting few times to their forum about the lack of information available and getting replies from the resident electrical engineer that replies to questions about the products, when I looked for the updated firmware again, it was nowhere to be found. Anywhere on the Internet!!! Links from Googling led nowhere! Won't be going there anymore!!! Also the trial website that I was able to connect to the data stream once no longer works.
Hmmmm.
Good luck, Larry. Be sure you have a full tank and watch out for your dear friends!!
