Does this Help? Not sure if the sentences are device specific, and it's a bit dated. But this could be a good place to start. http://www8.garmin.com/support/pdf/NMEA_0183.pdf I Found The link above in a post on the Garmin Forum here.
There is a Adafruit Ultimate GPS Breakout - 66 channel w/10 Hz, it has position accuracy of <3 meter, velocity accuracy of 0.1 meter per second and cost around 40$. For a working model with Raspberry Pi, here is a tutorial.
I use GPX format to transfer data from and to Basecamp. The older version I use can also export csv, and import kml and csv. But since I use GPX for export to and from the GPS unit too, I prefer that format for all exchange. You can however not use the Garmin based .img files inside QGIS.
I would log in to Samsungs page and see if it shows the last position thereunder find my phone. Can also have the option to wipe it or ring it.
The code looks like the USNG or MGRS coordinate system, see https://en.wikipedia.org/wiki/United_States_National_Grid and https://en.wikipedia.org/wiki/Military_grid_reference_system for further details. 12RVU indicates that you are in UTM zone 12, somehwere in Western Mexico. You might need to read the manual on how to change the setting (I don't have the ...
If you divide those "strange" latitudes and longitudes by 11930465, you get the North and East degree values you expect: But don't ask me why ;-)
You don't actually need the full Pathfinder Office suite to get your data off the handheld and onto a PC, all you need is the Trimble Data Transfer Utility. It's a free download. The same utility is included in the full Pathfinder Office suite, but Trimble makes the data transfer utility freely available since (as you know) the people using GPS in the field, ...
If you download Pathfinder you can install it without a key and use it just to transfer the data off the device. All the other tools are disabled but you can at least get the data you need. If that's not an option you can pull the files manually but you'll need Pathfinder eventually to recombine them into SSF files that you can export/use elsewhere. When ...
There is a relatively detailed discussion on this topic here which is still largely valid. Afaik there are few if any library to perform map-matching out of the box. It depends also on which data you're using for the road network. In the case of OpenStreetMap (OSM), take a look at my profile for ref to an available API.
There's no solution. Pathfinder can handle only native ROVER files.
If I understand correctly you want to divide, or at least classify, the track into legs. You've got a couple of issues to face, and this probably can't be solved with a simple field calculation. If the GPS data has a single coordinate for a stop, then you'd create a variable called count, then start at the first point and iterate through each following ...
