<p>Hey Jorieke,</p>
<p>What your question describes sounds like fleet management. I just
found <a class="moz-txt-link-freetext" href="https://www.traccar.org/">https://www.traccar.org/</a> which looks pretty well maintained
(88 contributors on github, latest code update only a few hours
ago), is open-source and seems to provide exactly what you're
after, without having to reinvent the wheel.</p>
<p>Hope this helps,</p>
<p>Laurent</p>

you can use a script to copy the files, compress them and send
them.<br>
<br>
Android should have something equivalent. If not Microsoft
Visual Studio 2017 can build something that will run on android.<br>
<br>
We seem to be forever seeing requests from students to write
software for OSM and HOT as a project.<br>
<br>
This one is a natural. <br>
<br>
Enabling GPS tracking is heavy on a battery life but you can buy
power packs quite cheaply to extend the life. I wouldn't
connect it to the car battery, the voltage fluctuates to much
and it will shorten the smartphone life down.<br>
<br>
So basically you want a program that will grab the GPS tracks
every x minutes and compress them. Technically zip is fine but
the problem with zips is they can carry malware so use something
else and gmail won't accept them anyway.<br>
<br>
Then it should just email these back to the server. There
should be an API to allow the software to write to something
like Gmail on the smartphone.<br>
<br>
When gmail finds a connection it will send the messages home.
No fingers needed other than to connect to Wifi for gmail. This
one is the simplest.<br>

href="https://developers.google.com/gmail/api/guides/sending"
moz-do-not-send="true">https://developers.google.com/gmail/api/guides/sending</a>
has got the basics.<br>
<br>
The other way is to use the signal that the phone uses to
connect to the mast. There are 140 / 160 characters at the end
of the packet which are unused. This is the basis of SMS text
messaging. In Europe, North America phone plans often come with
unlimited SMS text messaging, Africa maybe different. The
advantage is you can collect the data in real time. The
disadvantage is the store and forward method of email is a bit
more robust.<br>
<br>
There are SMS APIs that will run on a smartphone but my
impression is these vary according to the phone so an SMS based
solution that ran on any phone might be more difficult to build
but someone who knows more about SMS might be in a better
position to sort something out. <br>

<div>I suppose easy to use is core, so options with manually

<div>Hi Jorieke<br>
</div>

<div>There are small vehicule gps logger, some very
precise reading various satellite networks. I
tried a Columbus. It did work very well but could
not replace the battery.</div>
<div><br>
</div>
<div>Search simply for vehicule gps logger. This
Ebay link show various models, some with an USB
connection and / or sim card.<br>
