i have GPS chip that i want to attach to the laptop. the idea is to track the laptop wherever it go.
i have create a system and , the system installed in laptop is,
1st GPS acquire the location.
2nd laptop send the location to server
3rd server display it in web browser
but now i have a problem in this system, sometimes when laptop want to send the location to server (step2) it must connected to internet, and sometimes internet access in someplace is bad, signal strength in someplace is bad, so sometimes the internet is down and unable to send the location to server, this is the main problem , so i have an idea, how can i access that GPS chip location directly?
so the step will be.
1st GPS acquire the location.
2nd server seek GPS Chip location by Serial number of GPS chip
3rd server display it in web browser
is that posiible?
No. GPS chips themselves are the only part of the system that can track their own location. You can't track a GPS chip without being in contact with the chip.

Is it possible to use the free GPS service to send other types of data such as plain text/XML/HTML??
E.G. systems for taxi companies - each car has in it a box which receives and sends information to and from the controller/ dispatch, back in the office. The driver can view all bookings and accept them, as well as tell the controller when the customer has been picked up and when they have been dropped off.
Is this all possible via the free GPS service? Or would the system's manufacturer have to pay to to rent a private satellite? Or would the system be using something similar to a mobile phone network? I would think it would be one of the first to options, as constant reliable signal is vital.
I know the question above is pretty open, and it's not what I'm too desperate to have answered...I just want to know if it is possible for me to build a device with a GPS receiver and have it send text and XML via the free GPS service?? (I want an admin to operate a team of employees from a browser, like with a taxi fleet management system).
No, GPS is a chip with an antenna that can receive only Location data.
It is not possible to send data via GPS.
All that devices that drivers, taxies, busses, tolling system use, send their data via mobile phone network.
So a device needs such a communication chip and a sim card.
Then you can send what you want.
I have a crazy dream that one day I'll be able to way into my rec room and my lighting system will turn on based on my proximity to the seating area. I've played with home automation (SmartThings most recently, the proximity sensor is unreliable and has no way to measure room area proximity), motion sensors, etc... but none of them actually do what I want, and that is detect if I'm in a room for real, not if I'm waving my arms in front of a sensor.
One idea I had was to measure the SNR between WIFI devices. I was thinking of playing around with some wifi survey tools and see what I can measure in my home. The problem I think will be sensitivity and range. Wifi's range is typically intended to try and cover a home, so if I go that route, I'm worried it'll be a waste as I'll only be able to measure when I arrive home, not if I'm in a specific room.
The other approach I'd like to try is Bluetooth 4.0 LE. The Bluetooth GATT specification includes a Proximity Profile, but the problem with profiles is it's something that a Bluetooth enabled device would share with another device it's peered to. e.g. You have a proximity sensor in your pocket and it shares proximity info with a PC or another device.
In my case I'm hoping to try using my iPhone as the marker, and my HTPC as the measuring system. The HTPC can continuously measure the RSSI or SNR of any paired Bluetooth devices without having to actually exchange profile data with the device.
I could do something like write a Windows app/service that registers or watches for a paired Bluetooth device to connect. (such as when I get home and my iPhone auto-pairs with my PC, just like when you get in your car and it pair with your stereo) From there it would measure the SNR as a source of distance information. If the SNR is high enough (least noise, strongest signal) it could automate doing something. I was thinking sending a HTTPS call to my Smartthings hub to turn on my lighting system.
When the SNR drops too low (lower signal strength), it would again send a call to turn off the lighting system.
This method could work with any device that bluetooth pairs. The concept would work with pretty much any platform, not just Windows. Like in a Raspberry Pi with Bluetooth.
Does anyone know if this is possible or am I crazy? I was going to grab the Visual Studio C# 2013 Express IDE when I get home and see what the Windows 8.1 APIs let me get access to.
Also, Bluetooth 4.0 LE should be nicer to use. I was hoping that a heavy, full Bluetooth connection wouldn't be needed as I simply want to detect the device within a small range. (25' of free air)
Thanks.
Me and my team we are working on a project for University. Our goal is to prevent people that are outside of a specific range to enter our wireless network. Lets say u are sitting in Starbucks and next to that there is another coffee shop. If u are a starbucks customer you will be able to enter the network and surf the internet. If you are sitting at the coffee shop next to starbucks though u will still see the wireless on your device but you won't be able to connect, or if you connect you will get kicked automatically.
My question is . Is there a way to get all the mac addresses of all devices in a specific area (Sturbucks building) and then only allow those to enter the wireless network. If thats possible through a mapping of a network or a device we don't care. We just want a way. And also is there a way to determine where exactly is a device,its location ? With or without a GPS.
The answer of all your questions is: NO.
You cannot get the mac adresses of foreign networks (sturbucks) without hacking the routers
You cannot get the location of a device in general. If the device is connected to your router, hotspot, Wlan, etc, you then could know that. In generall you cannot get the device GPS position, only if the user of the device allows that.
The other location possibility is the cell tower the user is logged in, that does not help you because you will not get the info in wich GSM cell the user is connected, without hacking the GSM network, and probably sturbucks and the uni has the same cell tower.
Remain wlan locationing: Here the same, the device might know it but you not.
Update:
There is one solution I remember now. Remeber the waste bins installed in London on public roads, they track when user pass by. They behave like WLAN devices, and track the mac adress. You could create such a system, maybe you cannot buy that. And place it near the entrance of the shop. Users which pass by have their mac adress recorded, you send that mac to your special wlan router and add that macs dynamically. Another possibility would be the use of bluetopot but this has to be enabled on the phone:
Look at the system how Apple's low energy blue tooth "location beacons" work: It is build for indoor positioning. you can triangulate the signal strength of a device. But probably the effort is beyond your project budget. (And still the useres woul dhave to enable blue tooth)
I am new to using arduino board. I will like to connect my samsung s3 to a medical device via a an ardunio board.
The first idea is to send/recieve data to/from the phone to the medica device via usb on an arduino board and the medical device recieve/send data from/to my phone via usb on the arduino board.
The second idea is send/recieve data to/from the phone to the medica device via WIFI on an arduino board via usb and the medical device recieve/send data from/to my phone via usb on the ardunio board.
Thanks for your proposed solutions.
All problems, including this one are best approached in increments. In this particular case, I assume you already have an arduino with a WiFi shield and a Samsung s3.
You don't mention the medical device or how it is programmed. But first, concentrate on how to get the Samsung to talk to your PC via wireless. In doing this you will learn a lot about how to write code for the Samsung and how to write code for a PC/Wireless connection. There are probably already sample applications that do this.
Next, identify how the arduino board will connected to the medical device and make the same connection from the arduino to your PC. Get this connection to work. I know there are many examples of how to do this.
Next, get the Samsung to talk just to the arduino board which maybe turns on an LED. Since you already learned how to code the Samsung to do wireless in the first step, then this step might be easy.
Next, connect the arduino to the PC and have the Arduino pass data back and forth between the PC and the Samsung.
After you have this "stack" of: Samsung <==> Arduino <==> PC working then consider what it would take to replace the PC with a medical device so that you have:
Samsung <==> Arduino <==> Medical Device
You can design your own series of incremental steps based on your more specific knowledge of the devices that you have. But the idea is the same, each step is something easy to do and easy to debug. But taking all the steps results in a complex system!
No one is able to do what you want on the first try (unless they have already developed the same or similar system). But everyone is capable of learning new material, if they are persistent.
Please keep me informed as you work on this, it is an interesting project!!
We are planning for vehicle tracking system. We would like to relay on GPS Tracking System and view position report via Google Maps.
For hardware requirement we are thinking of GPS modem that can transmit data to our system.
Which GPD Modem is suitable for my project?
Use a smartphone. Haha.
On a more serious note, since it's for vehicular application only, there are a lot of companies that manufacture GPS modules (u-blox is one of them). Just google and you'll find thousands of companies manufacturing them. But before you choose a GPS module, make sure you check the regulations of your target country. If the module works on the Iridium satellite network, countries like India & China won't allow it as Iridium frequency is close to their military frequencies. In Europe you'll be better off with the Inmarsat network. So, do your homework & you should be good.
Also, if you're developing your own map interface, you might wanna ask the manufacturer if they have any existing mapping interface you can hook into or disable. You mag be charged for either.
All the best!
Are mobile networks (like GSM/GPRS/UMTS) available where you are?
if so check-out the tracking products from this site or this site (Google keywords: GPS GPRS)
If not, you should consider a custom solution, maybe someone like this company can help...
I have worked on a project that involved sending data over GSM/CDMA network. It used a simple GSM/CDMA modem connected to an embedded linux device and was a stationary piece of hardware. Attach a GPS device and it may very well be a tracking system. The problem is when the network drops or the device moves out of the network coverage area. I am not sure if there any GSM/CDMA modem available with GPS added to them as we didn't have this facility in our hardware and it was very much desirable. We needed to use a separate GPS device, mostly iPhone, separately to determine the lat long of our device.
You can use any GSM/GPRS modem equipped with GPS device. The modem will forward the GPS data to your central server through GPRS and at the server side you just need to process rcvd data and display it on google maps.
