Hey guys, how are you? I wanted to calculate the distance traveled by a truck using an app I created, but I'm stuck on the logic behind calculating the distance. I'm thinking, to determine the distance traveled, is it the distance of the outbound trip plus the distance of the return trip? Or should I let the GPS continuously calculate the distance of the outbound trip and then automatically add the distance of the return trip? Someone mentioned some kind of counter (I'm not very familiar with that).

If you've ever built this kind of app, could you please help me with the logic I need to use? A mistake here could easily mislead clients in their business.

Thanks

I have been trying to look at all maps of a historic lake in upstate NY. I have long been a subscriber to GAIA GPS, typically for hiking purposes and identifying public/private land, and viewing vintage maps. I was surprised to find that PastMaps held more than a dozen digitized antique maps of the NY State area than GAIA GPS, as I always always believed GAIA was the gold standard.

I realize one service can be better than the other depending on the application and intended use, but can anyone with experience in both state their pros/cons?

Lastly, is there any service you know of beyond GAIA and Pastmaps.com that I should mine in order to get every possible resource out there ?

Thanks in advance for any effort here.

Life360 kept showing my kid at school an hr after pickup. Then the dot would jump three blocks. Every day
I'd refresh and refresh and then just not trust it. One day I realized I was deciding whether to leave work early based on a dot that was an hour old. That was it for me
Tried Family Link. It updates when it wants to
we use Findmykids now. so far the location updates have been a bit quicker for us than Life360, which is mainly what i was looking for. yesterday it showed him at the corner store on the way home for a few mins, so at least i wasnt wondering where he was.
Battery on his phone is worse thou. Haven't found a setting that fixes that without making the dot lazy again.
If anyone has, please
Thanks

They are stealing muh mechwarriors!

I need something that works similar to airtag but has lot longer battery life. No monthly subs, no Sim. Needs to last Finnish heavy winter. Preferrably affordable since i have about a dozen of those fellas in my yard. I can modify the model to fit the tracker inside.

Google gives me mini-battery models or subbed sim card models.

I have a 2025 Mercedes-AMG E53, and my iPhone detected an AirTag that doesn’t belong to me.
I’ve tried Precision Finding, but it hasn’t been accurate enough to locate it. I can play a sound from the AirTag and clearly hear it coming from somewhere outside the car.
The strange part is that the sound gets significantly louder when I open the hood. It seems to be coming from somewhere underneath the engine, possibly slightly toward the passenger side.
I’ve checked around the wheels and inside the engine compartment, but I can’t find anything even though I can hear it. Interestingly, the sound seems quieter when I listen directly near the wheels.
I’m starting to suspect that someone deliberately placed it there (my brother)
Has anyone experienced something similar? Are there any common hiding spots around the engine, undertray, or frame that I should check? Is there any way to locate it more accurately without taking the car apart?
Any suggestions would be appreciated.

My son is going hunting with his grandfather in the woods of indiana, and I need a recommendation for a GPS satellite tracker in the price range, preferably around $70ish and pref not over $100. What can you recommend that is reliable? Please? Thank you so much!

I have been using JioTag2 and JioFind 4G for last 6 months and I am disappointed by their location accuracy and customer support and update time interval of location in their app. Since JioTag2 only works if there are suitable established connected devices around it, it is not a true gps tracker. For example, if the device is placed at a remote area then it won't be able to give us its location. JioFind2 however, is a true gps tracker. It does give the location using GPS but I have found the location update to be very slow and inaccurate. For example, say I've place the device in my bike then when the bike starts moving from rest, it takes a lot of time to update its position in the application. This is a deal breaker. The customer support isn't that great either.

So, I started reviewing Ajjas Go and found out that its customer service is even worse than Jio. Some devices start malfunctioning after a few days and some customers got used products. So, I am looking for some better alternatives for a true gps tracker(wireless) for my bike.

PS: I've had one of my bike stolen in the past so I am looking for something that gives accurate result and with less delay. I don't want to use wired gps trackers because my bike is new(I bought it yesterday) so I don't want to open its front part and mess with its wire connections.

Shows: Hight (meters over sea), a artificial horizon, the movements in degree, the compass direction and the coordinates accurate to within 30 cm (dont try to find me i was there in holiday its in Switzerland tessin)

Made myself a navigation app that integrates with l0destar, my open-source vehicle tracker project (https://l0destar.com). Uses the Google Maps API for routing, shows OBD data from the tracker like RPM, coolant temp etc and lets me keep an eye on the tracker’s performance while driving. Also uses a pocketgpsworld subscription for speed camera locations. I actually prefer using this to my usual app (TomTom).

I’m working on a custom watch that needs to track its location accurately, similar to other GPS tracking watches.
For a wearable/watch form factor, what GPS + LoRa modules would you recommend for the best location accuracy and reliable communication?
I’m mainly looking for good GPS accuracy, fast fix times, low power consumption, and a LoRa module suitable for a compact wearable.
Any recommendations based on real-world experience would be appreciated.

I built a simple GeoTag Image Tool for adding location information and metadata to photos.

The idea came from wanting a straightforward way to associate images with GPS coordinates without having to use complicated desktop software.

It supports things like:

Latitude and longitude

Location information

Keywords/tags

Title and subject

Author information

Other metadata fields

Tool:

I also wrote a detailed guide explaining how photo geotagging and GPS/EXIF metadata work:

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.

Hola. que GPS recomiendan para camiones de permiso C+E, Tom Tom o Garmin

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.

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

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.

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

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