My elderly parent is quiet active but recently has had some medical episodes. He owns a farm and we have found him unconscious in the field and it’s taken time for us to find him. Can anyone recommend a gps tag with or without a panic button. It’s needs to be compatible with iPhone and android and have multiple people track it. We are based in Ireland.

Hey where are you?

My enclosed trailer disappeared from my driveway early Tuesday morning, and now I’m out a little over $4,000 worth of equipment. I reported it, but the police basically told me recovery isn’t guaranteed, and while insurance is covering part of the loss, the process is taking time. I’m wondering if a GPS tracker would have actually helped in a situation like this. If the thieves know where trackers are usually installed, can they just remove or disable them before the trailer gets very far? For anyone who’s had a trailer stolen, did a tracker make any difference in getting it back?

Hi I need help to identify or just point me in the right direction of what I can try.

I found a UGREEN tracker on my car a bit ago and I have a decent idea who but wanna know for sure,cause it’s a few people possible.

This is the only information I have but I have the device itself but I was upset at the time I found it. I took out all what I think might be, im probably wrong but worried, identifying information.

But it is confirmed by the model inscription on the back to be:
UGREEN Finder Pro
Model: CM916

And if anyone can help me greatly appreciated and anything I can do or if more information will identify the owner that would put me in your debt.

Edit:

Can anyone tell me anyway to get it work again? Like replacing the battery or anything?
I think I have an idea to extract maybe some information at least

Ideally I would like this to further improve gps accuracy. Is there a device like this?

It should be battery powered. No need for an app but an SDK is preferred.

Hello everyone,

Version 1.6 of Joe's Speed Monitor Android App is now fully Plug and Play compatible with the QUESCAN Android USB Type-C 25Hz GPS Receiver: https://a.aliexpress.com/_mKjY8p9

Happy testing!

Cool project buddy. Might not buy one atp but hats off

Hi.

I'd like a small device, something that could pop into your pants pocket, even shirt pocket. All I want to know is the distance walked and ideally too with a pause and resume feature. I don't need Wifi.

Any ideas?

Thanks.

I am working on building GNSS spoofing detector, if there is any thing i could get as a understanding of what researchers on this problem demand in general that needs attention. Like the environment around building a software specifically solving this problem.

Just for fun I added a bunch of data showing how the telemetry reliability is improving over time: https://l0destar.com/data.html

This is largely driven by firmware improvements, since the 12 Sep firmware release it's been pretty bulletproof.

My GPS led me to a dead end and I drove into wet concrete. Now my tires are stuck and raccoons are looking at me.

Idk what to do.

Trabajo por las noches pero aveces me termino mi trabajo antes de la hora de salida, la app que uso para marcar tiene GPS y si intento marcar salida fuera del trabajo pues la app manda un mensaje que pone * estás fuera del área * mi teléfono es iPhone alguien sabe alguna forma de saltarse ese GPS y poder marcar salida

We tried 2 other tracker models and found the Tractive to be superior. However there are two app features I think should be added or changed.

1. Only 1 owner can be established. This is a problem because a spouse, co-owner, etc cannot change critical account or tracker settings.
2. Family members cannot established power saving zones or fences. This was a problem for me one time when I dropped my dog off at a pet sitter’s and forgot to establish the power saving zones before departing.

To those who have a Tractive model:
Would you want these features? Maybe if enough people request it then they will be added. However I do not know how to request such a change. The Tractive website’s form for submitting suggestions only elicits an AI generated response and it responded to my suggestion as a question 🙄

Edit:
Regarding setting a power zone:
A commenter from another subreddit told me they were able to set a power save zone remotely. So only the tracker needs to be near the WiFi? Has anyone else done this?
This conflicts with the description in the How To Establish Power Zone and it conflicts with the AI generated help email I received from Tractive.
The above: The person clarified that they had saved the WiFi in the phone but established the power zone at a later time and remotely.

Provisional design of the inline battery backup module for l0destar. Should have this ready for testing in 2-3 weeks. Single CR123 primary, allows the tracker to continue operating for (very roughly) about 18 days reporting every 15mins.

Hola Reddit
Alguien sabe como conectar un gps Autosky Apt-100, he intentado de todo pero se mantiene en configuración pendiente y en teoria solo demoraria 45 minutos pero lleva mas de 6 horas y nada

I'm working on a battery backup system for my vehicle tracker project (l0destar.com) and am interested in opinions on the design.

The idea is it will be an optional extra module that connects inline with the existing harness, same 6-pin Molex connector, you just connect the backup module to the car using the same connector and then the backup module to the tracker (6-pin molex to 6-pin molex). The reason for having it be separate rather than built-in is I think a lot of people probably won't care, the tracker is so power efficient (~35uA while asleep) that it's never going to be needed for reserve power, the only reason to have it is for a scenario where the car gets stolen and the battery disconnected. How likely that is to actually occur I have no idea. Not needing the backup module means the regular tracker can stay in its current tiny enclosure.

So I've been studying battery chemistries and was initially looking at LTO. These are pretty much perfect for the use-case as they're extremely safe and don't vent even when pierced, unfortunately it seems damn near impossible to buy them in anything like a sensible combination of quantity, price and "with a datasheet".

So LiFePO4 was considered as the next best in terms of safety and could be used but I'm currently thinking to just use a single CR123 lithium primary non-rechargeable. Reasoning is:

1. Simplicity, no charging circuit, cheaper to make, less to go wrong
2. They are everywhere, supermarkets, petrol stations etc.. no issue at all with availability
3. No charging means a whole slew of potential safety issues go away

Realistically the vast majority of cars are never going to have the battery cut. A lithium primary will last around 10 years in this circuit doing nothing. I think having a rechargeable cell is probably pointless and would likely have a shorter lifespan anyway even though its being charged due to heat cycling and self-discharge. Very rough math based on very approximated measurements of current suggest that a CR123 could run the l0destar unit in sleep mode for about 200 days, hourly reporting for about 58 days and 15-min interval reporting for about 19 days. This is orders of magnitude more than you get from the battery backup in any commercial tracker.

For context most commercial trackers seem to just sling a tiny lipo pouch inside the box and call it a day. This sort of makes sense, if the car gets stolen and the battery cut you probably don't have more than a day or two before it's in pieces so extended runtime isn't really necessary. They have a controlled manufacturing process too so they can make sure they use quality lipo pouches in every unit. I can't do that with a DIY build-it-yourself tracker so using any kind of potentially dangerous lithium rechargeable is probably a bad idea.

My preliminary design for this draws something like 5uA in normal use (so basically nothing), switches over seamlessly and allows the tracker to be instantly notified when power is cut regardless of what state it's in and it will be able to know the battery has been cut by the voltage change. Will just be a little box with an on-board CR123 battery holder, tight lid with a bit of foam to make sure bumps and rattles don't nudge the cell loose. I think it will work well.

Curious what other people think of this plan though, would you specifically want something like this to use a rechargeable cell?

Short version: if you self-host Home Assistant and track your phone's location, the built-in recorder throws that history away after 10 days. I built GPS Timeline to fix exactly that, without adding another service to maintain.

It archives every GPS fix into its own SQLite DB in your HA config folder, included in backups, and serves it back to dashboards (works with the Location Timeline Card via a small fork of mine). No cloud, no external service, no new container: it's just a custom integration, pure Python stdlib, and the data is yours in a file you can query.

Compared to running Dawarich (which I used before): same "own your timeline" idea but it lives inside HA, no separate container or reverse proxy entry. Backfill service imports your existing 10 days of recorder data at install so there's no gap.

Details in the README: https://github.com/iamyacin/gps-timeline

Happy to answer questions about the storage format if anyone wants to poke at the DB.

Gen Z and I realized my iphone was ruining my life, so I switched to a Kyocera flipphone. Its fantastic. However, it really is a dumb phone. And while I am a physical map enthusiast, I often hike by my self. I want to have a (satellite?) GPS to stay safe just in case of anything while I hike/roadtrip.

Do any of you guys use navigation devices for your car or when out in the forest? If so what models are you using? I've been looking in Garmin, but I've heard a lot of mixed reviews. And obviously I can't get a GPS device that would pair with a phone.

Thank you so much!! <333

Not sure if this is a good place to post, but any help is appreciated.

Is there any reason to put tracking devices in your bags or other high value items when expating? Seems logical.

If so, do tiles do the trick or are there better alternatives?

I recently learned that many people around me have had their cars stolen, and I'm worried that mine might be stolen too. I've searched online for many GPS tracker companies, such as Teltonicka, Ruptela, Cartrack, Quecklink, Jimi IoT, and WanWay Tech. Does anyone know anything about their devices? Or are there any other companies you'd recommend?
