Answering your question in three stages: When I first read the question, I was thinking that you were asking if the GPS communicated back to the satellites in order to function as a GPS. That answer is "No" The ground unit receives the signals only. There is no way to track who is using the satellites, and no uplink from the GPS through the ...

The Classic Garmin GPSMap 64 can satisfy this requirement I assume the requirements are satisfied when this device cannot communicate with any other device and does not require vendor software (Garmin Basecamp) to retrieve the tracks and waypoints. Purchase vendor maps (24K/100K) on SD cards, or download the maps and install to an sd card using the vendor ...

I wish there was a solution that's both practical and 100% data secure, but I don't know of one. An open source phone, as suggested by Matthew, is probably the closest, but with that you unfortunately still need to expect to run into reliability problems – not something I would risk in the outdoors. Also, open source phones are probably among the products ...

There are some general restrictions which limit a device’s ability to phone home: For cellular networks a device needs a SIM card. For Wifi it has to be able to connect to a Wifi network (and the Wifi network needs to have an (unrestricted) internet connection). For Bluetooth it has to be paired to a smartphone or other device. For cable connections the host ...

Y'all are way overthinking this. Get an old and/or cheap smart phone. Don't put a SIM card in it. Install some basic GPS app and then tell it to forget the WiFi network (and turn off WiFi). If you don't need maps, you're done. If you do, I wouldn't be surprised if there are apps (probably OSM based) that let you side-load offline maps from an SD card; you ...

You are probably best looking at older and cheaper models to achieve this lack of functionality. Therefore you should look for models that don't advertise bluetooth connectivity, app integration or wireless connectivity. A curent example is the Garmin eTrex 10 which seems only to receive GPS signals, not to send or receive other data wirelessly. In this case ...

Thanks for the further clarification in comments and edits to the question. I think the answer is no, although I'd be happy to be proved wrong. I assume you want a lightweight GPS device that tells you where you are when you're hiking. If you want a GPS for your car that gives you directions, then that would be off topic for this site. If you want a GPS ...

Answering the updated question: Get a device that uses an external memory - i.e. (micro) SD card for the maps. You will never connect the device to a computer and may still have the actual maps on the SD card, just use a card reader. You can always sanitize the SD card prior to accessing it with the device's software (up to and including a complete ...

All GPS navigators on the market work as you’ve described. Two way communication is very battery intensive and costs money, so it’s only included in PLB beacons or devices like Spot, not your average GPS device. Some of them let you connect to WiFi or add a SIM card to download map or traffic updates but this is completely optional. So get the cheapest GPS ...
