I'm looking for a GPS with a good API. I would like to be able to send an address to it, and tell it to navigate to that address. I also need to pull the current location from the GPS. I'd like to be able to do this with the GPS hooked up to a laptop by bluetooth or even just a USB cable. I've looked at the Dash a little, but the mon...
I was wondering if I could access the iPhones Core Location framework over a website? My goal is to build a webapp/website that the iPhone would browse to, then upload its current GPS location. This would be a simple site primary for friends/family so we could locate each other. I can have them manually enter lng/lat but its not the eas...
I assume it doesn't connect to anything (other than the satelite I guess), is this right? Or it does and has some kind of charge? ...
My GPS logger occassionally leaves "unfinished" lines at the end of the log files. I think they're only at the end, but I want to check all lines just in case. A sample complete sentence looks like: $GPRMC,005727.000,A,3751.9418,S,14502.2569,E,0.00,339.17,210808,,,A*76 The line should start with a $ sign, and end with an * and a tw...
Can one be simulated by periodicly syncing with GPS and in the meen while working with the accelerometer? I know for example that the N95 accelerometer is invarient to rotation on the Y axis (while beeing face up/down). ...
I'm just starting to design some embedded devices, and am looking for resources. What I want to be able to do is to connect a GPS receiver to a lightweight SBC or mini-ITX, x86-based computer, and track a remote-controlled vehicle's location/progress. Ideally, this could morph into building some hobby, semi-autonomous vehicles. But wh...
From what I understand, the crystals on PC's are notorious for clock skew. If clocks are always skewing, what is the best way to synchronize clocks between machines with millisecond accuracy and precision? From what I've found, NTP and PTP are possible solutions, but I was wondering if anybody had any experience on stackoverflow.com! I ...
I am developing a web app that will be hit frequently by mobile browsers. I am wondering if there is a way to get enough information from the browser request to lookup position data (triangulation or GPS) Not from the request directly, of course. A colleague suggested there some carriers supply a unique identifier in the request header t...
I have an application that depends on gpsd and ntpd to accurately set the system time on a linux machine. gpsd is fed NMEA + PPS The application is punping ~25MB per second over the network and I think the loading on the system is causing jitter in the time somehow. (loaded PCI express bus causing irregular interrupt latency) I have a...
Has anyone researched how to access the gps chipset on a blackberry over usb so that it is unnecessary to transmit this data over the cell carrier's data network? Is it possible to access the GPS chipset, store information in a buffer, and open an interface connection (over the usb charging port), for access? Not sure if J2ME allows f...
Does anyone know whether the iPhone supports or will soon support the W3C Geolocation specification? I'm looking to build an app for mobile users, but rather than spend the time developing apps for every different platform (iPhone, Android, etc...), I'd much prefer to create a web app that makes use of the W3C Standard. ...
Hi all I have a GPS from u-blox.com with a USB-connection and driver. The driver installs a virual COM port that pops up when you plug the USB in. Using a hyperterminal I can then watch the flow of data from the GPS. Then I want the data in my program, not so easy... I have implemented some methods using the serialPort class to read f...
I want to allow only users with a 3G phone to use a particular GPS function. How do I run a check on the device before allowing that feature to be used? ...
I have a friend who is finishing up his masters degree in aerospace engineering. For his final project, he is on a small team tasked with writing a program for tracking weather balloons, rockets and satellites. The program receives input from a GPS device, does calculations with the data, and uses the results of those calculations to con...
Does anyone have any experience with the triangulated GPS used by the non-3G iPhone? How does it compare with 3G positioning? Does the iPhone 3G use triangulation in the event that there is no GPS signal available? Is there anyway to determine the accuracy of the non 3G coordinates? Thanks. ...
I'm using GPS units and mobile computers to track individual pedestrians' travels. I'd like to in real time "clean" the incoming GPS signal to improve its accuracy. Also, after the fact, not necessarily in real time, I would like to "lock" individuals' GPS fixes to positions along a road network. Have any techniques, resources, algorithm...
This isn't really a programming question, more of an ideas question. Bear with me. My sister gave me a well-used Nokia N95. I don't really need it, but I wanted it to do some programming for it. It supports a few languages, of which I can do Python. My question is this: what to do with it? If I think about it, it has a lot to offer: i ...
How do I calculate distance between two gps coordinates (lang,long) ...
I have a project that has a list of gps coordinates. I would like to find a way to make a simple map of those coordinates (possibly just one at a time). The map should have basic street info. This part of our project is pretty simple so I don't think it needs to be an exceptionally feature rich product. This also means it shouldn't be r...
I'm trying to write a simple GPS based application for my BB 8800 (with Airtel, India). But for some reason my code getLocation(timeout) always returns with a non-valid location (only after timing out). I tried different combinations of criteria parameters with no success. I'm pretty sure that the problem is not with my code because ...
