I moved your topic to an appropriate forum category @foramagicstory.
In the future, please take some time to pick the forum category that best suits the subject of your topic. There is an "About the _____ category" topic at the top of each category that explains its purpose.
Writing this description what a Garmin Glo is would have been your task if you would have read carefully the forum-guidelines.
A garmin Glo is a position-determining device that receives GPS-signals and signals from the GLONASS satellite positioning system which means 24 additional satellites are used and the device has an position-update-rate of 10 times per second.
I guess totally regardless of which country you live in the effort to import a garmin glo
will be smaller than trying to replicate the precision of a garmin glo device with arduino and some GPS / GLONASS capable receivers.
How about buying a used smartphone that has GPS? I estimate a used smartphones 5 years old starts at $50.
It would be very interesting in which country you live. North-Corea? I guess not.
If you don't want to share your country.
You have to get more specific what components are availablein your country.
Regardless of which product you use without checking if a certain product is available in your country this all is 100% theoretical.
How about this product?
You have to be much more specific
what is your budget?
etc.
Thank you for taking out time and researching for me, like I said I don’t have access to garmin glo and similar devices - inc. bad elf dongle, these are marketed more for usa. For them it’s reasonable to spend $100 but with shipping and customs it’s costing me over $350.
I’ve access to arduinos & it’s modules, and they fall in my budget too, I’m looking to spend max $50 on diy..
I also don’t need very high gps accuracy like the aforementioned products.
Me personal I don't like apple products. My children use iPads for school and through this I have contact to them. The purism and lack of functionality at multiple points is what I don't like.
Anyway.
Search strategies can by applied to anything
My assumption is that building your own device and to feed in the GPS-data most directly to see your position on "apple-maps" will be a hard thing to do as apple's security philosophy restricts so many things.
I tried to find a "make an iPhone easier to use for old seniors that are unable to learn the complexity of a modern smartphone. You might be unable to imagine this could be too complex or shaking your head about so much "dumbness" yes it is there.
And as apple is so restrictive for an unrooted / non jailbroken iPhone there is no possability to use an alternative app for functions like phoning etc.
For a windows device I would simply install autohotkey which then emulates manual user-input. IMPOSSIBLE on iOS-devices.
I estimate that it will be 5 times easier to get this to work on an android-device or a windows-tablet.
So I did a search for google maps data.
with this search
I found this website which gives some insight how it works
If you want it for iPad I would look up the app-store and search for apps that can work with GPS-data.
Of course there are a lot of cheap GPS-modules with a serial interface. So getting the GPS-Data coordinates is a pretty easy thing. The hard part will be to feed-in this data into your iPad to see your actual position on a map shown on the screen.
