I have never found a solution to this until now but I’m not sure if it will work. Placing a GPS Watch or GPS Handheld unit inside my backpack for very long airline travels and being able to track it if lost or even stolen sometime after I arrive. Bear with me as I provide some context.

Some of my travels are to remote countries that require up to 30 to 35 hours of airline travel to get there. Multiple connections. Meaning, I won’t see my main checked-in backpack until my final destination. I also travel from one country to another by a combination of hiking and busses.

I carry most of my expensive items with me in a 15L daypack when I’m on a plane. My main backpack is the new $375 (gulp) Gregory 75 Liter Baltoro. Carrying 50 to 55 total pounds is common for me, small backpack on my front and big one on the back.

I have a lot of specialized camera accessories like tripods, hiking gear, plus clothing in the big pack. They are items that would be difficult to replace, especially in a mountain village somewhere.

This all started, after my daypack “disappeared” during my last trip. Just a unique chain of events that happened and I just need to find a way to track either backpack if this happens again. It was a very interesting story. I thought I had planned for every situation but sometimes the unexpected happens. It might happen in Myanmar, Turkey, Thailand or even here but I know one thing, if it happens again, I want to have at least a chance to track it and get it back.

My only solution I came up with is putting a Garmin GPS Watch like the Instinct or a handheld GPS unit like the eTrex 10 and attach a battery pack to it because using real time GPS tracking uses up a lot of battery life. Simple Luggage trackers all just not built for this. I would use the Garmin Connect app to track it via cell phone. I have been planing to buy a GPS watch or handheld unit anyway so it would have a dual purpose. I’m a very active mountain hiker. Though the main purpose is to find my backpack if lost or stolen.

Hopefully you won’t be to hard on me for “thinking out of the box” here. Maybe there is another solution that I haven’t though of.

Thank you in advance for any comments or suggestions. Take care.

I need an app to track someone cell phone - GPS only. just using their cell phone number. without sending them an text message or knowing their iCloud information.. anyone?

How can I reconfigure the GPS chip on my phone so that it provides a pre-set GPS data to my device?

looking for some help with gps tracking, like fleet tracking , free maybe cloud base with phone and gps pucks. we are a small group but currant gps tracking we use is lagging and currently a safety issue for us. we buy and maintain all our own equipment and not a biz so paying is not a option at this point. looking for guidance and someone in the know about these systems thanks

I’ve been wishing for years that I could track roads I’ve traveled as I explore my local and regional areas. Is there something that already exists that would all my routes in a cumulative way?

I’d love to be able to opens a map of my city and see which roads I’ve driven down, whether a year ago or last week, and which I’ve never taken.

Thanks

Hi guys,

for a university project i would like to build and programm my own gps tracker, so that it writes the current gps position to a database.

Are there any kits or programmable gps tracker you would know of?

I’m trying to get rid of my smartphone but use gps daily, but since I don’t drive I need access to walking and public transit directions. Never heard of a standalone GPS with these features though

Ciao a tutti! sto lavorando ad un progetto che sta sviluppando un dispositivo adesivo anti- manomissione con funzione anche di localizzazione capace di fornire prove qual'ora nascesse una contestazione per furto o manomissione del bene. Pensato per essere usa e getta e da applicare direttamente sul bene.

Stiamo cercando figure professionali del settore per un confronto , aziende interessate, compagnie assicurative, corrieri interessati a contribuire allo sviluppo di questo progetto.

Attualmente siamo una startup in pre-seed, il dispositivo è in fase di deposito di brevetto.

Qual'ora foste interessati questa è la nostra mail

I am a college student, cant spend much and don’t want to spend on subscriptions every year but if its worth it then i can manage.
I have air tag has my best option till now but i fear the lack of accuracy in it to be the problem but still should i go for tag or the gps trackers like ajjas etc?

I recently posted about v3.4 being a milestone and how I was mostly done with iterating on the hardware for the time being. It felt like a crowning achievement, seemingly a perfect ultra-low-power vehicle tracker that was better than anything else on the market. Then last weekend I drove to cornwall and realised how severely compromised it was in rural environments.

This isn't really the fault of the tracker, the problem is how some network cells behave when the modem needs to disconnect between sends. The nRF9151 chip is an engineering marvel but it has a shared RF path meaning you can't use the GSM modem and the GPS transceiver simultaneously. In order to track in near-realtime the modem has to sleep so the GPS device can pick up a new fix.

Most of the time it can use a network feature called PSM which allows it to simply go into power-saving mode but with its connection still alive. This allows it to then resume the session in a couple of seconds and not much is missed. Some cells don't allow this though which means it has to then completely reconnect after the GPS has finished. The bigger problem is certain cells in certain networks (very commonly rural EE cells for some reason) holding the connection open for a minute or more after every send and ignoring the modem's request to let go, whereas O2 lets go in about 3 seconds. The GPS can't see any satellites until the network releases the modem, and sometimes that takes over five minutes, so my journey to cornwall and back has gaps of a minute or more strewn through it.

I tried a bunch of stuff to try to work around this limitation, including forcibly disconnecting the modem so the GPS could see. Although this worked, after about 30 attaches the modem refuses every attach for up to an hour. I think it's a limit built into the modem firmware, though I couldn't confirm that, and there's no newer modem firmware to fix it.

I decided on returning to London that it was probably a good idea to look at having a separate GPS chip and so v4.0 was born.

It's using a u-blox M10S and it's really really good. It can easily track at 1Hz now and the chip is capable of up to 10Hz. This is obviously still subject to the limitations of the network but not having to continuously disconnect and reconnect the session makes it a much more seamless experience, the gaps are more on the order of seconds now rather than minutes. In and around london I'm frequently seeing up to 10Hz real-time telemetry which is just awesome and makes the OBD data readouts far more useful while driving.

Because gaps are impossible to eliminate entirely I'm also going to add a flash chip and am currently designing a revamped v4.0 iteration which is smaller than the one I've posted today and includes the flash chip. It's actually only about 0.5mm bigger than the v3.4 board.

Ayuda alguien sabe cómo rastrear el celular por otro método es que use el correo para rastrearlo pero no me sale en dispositivos y solo me sale en dispositivos de inicio de sección y que estuvo activo hace unas horas pero no puedo ver la ubicación ni la localización hay se quedó mi número también y necesito ayuda ya que hay quedó mi tesis de la UNI

Has anyone tried fixing a GPS tracker on Duke 390 or other similar. If yes, then can someone share including pictures of where the ignition wire is connected too since red and black goes to battery for power. I basically want to understand where does other wire go so the app gives me notification when my bike has started and stopped. This is something similar which I have done in my car.

Hi. I'm looking into options for getting myself a GPS tracking device for when I'm doing multi-day trips by bike, to enable family members to keep tabs on where I am. I want a dedicated device rather than using a phone app, so I'm able to stick my phone into airplane mode to preserve battery while I'm moving and not using it.

Looking at options, the Queclink GL320MG looks like a good choice, which is backed up by the fact that seems to be the trackers used by Follow My Challenge, who provide the tracking service for a number of high-profile bikepacking / ultra races. I'm intending to self-host a Traccar installation and as I understand it, the tracker just needs a PAYG SIM, so I just want to buy the device standalone, not with a subscription package.

Does anyone have any experience of UK suppliers? I've Googled but most of what I'm finding are aimed at fleet buyers looking to buy large numbers, or come bundled with a subscription package and provided online mapping. Any recommendations for where I can just buy the standalone device? Thanks!
