WorldDev commented on Ask HN: How do GPS tracking devices send signal    · Posted by u/WorldDev

> You need to pay to send the GPS data to the satellite.

No, the device is only receiving the position data from satellites. It then sends the position via the network (internet) to you.

The phone will need network (internet) connection so you require a SIM card. GPS tracking devices usually use special data plans where the providers only allows a couple of megabyte per day, and thus cheaper than any phone plans.

https://www.eiotclub.com/products/gps-tracker-data-plans is $2.20 USD/month.

https://lightbug.io/product/lb-dev-ze2/ for example is 2-3.50 Euro/month if sending every 30 minutes is enough. The company probably pays less than 1 Euro for their data plan before they resell it to end users.

Ah, that makes sense. Thanks for the explanation.

MP3 player with an AirTag hot glued to the back

Thanks for that suggestion. I thought that AirTag could not be used to monitor kid location though, as they will deactivate if far from the original iPhone.

What's the use case? Music playing depending on the position?
WorldDev · a year ago
Nope, just 2 independent features, in 1 device.

Don't they have flip phones that do that? Shouldn't people be able to call for help if they're going so far that they would need a GPS?
WorldDev · a year ago
I can look into flip phones, yes, that's a reasonable approach. I was hoping to avoid all the rest of the phone functionality.

I have a similar usecase (offline GPS for biking). For that, I’ve repurposed an old, unsupported Android phone. I keep the phone permanently in Airplane mode. It plays music files and I can put Navit on it for offline GPS.

That's fair. Definitely a solution, but I was hoping to avoid that.

very rough metric

The argument is, fundamentally, that it's not even that. It's not a rough proxy for the thing you want to evaluate, it's not any kind of proxy for it at all - that's a qualitatively different argument from your restatement of it.

If you want a very rough comparative proxy, an obvious one is 'Brave is a much smaller downstream consumer of Chrome, Chrome has a larger security team/infrastructure than Brave has employees'. I think you can draw more meaningful conclusions from that alone than from CVE tallies.

Regardless of this point, why are 0 CVEs for Chrome also CVEs for Brave?

CVE numerology is not a good way to assess comparative security. A search of the comments of local CVE enjoyer tptacek is a decent jumping-off point:

Yes, I have seen that argument often. I agree number of CVEs is a very rough metric. However, I am still confused as to why none of Chrome's CVEs would be Brave's CVEs?
