The concept sounds great. I have many recorded UAV flights that I would love to see from google earths perspective as though I was flying again. To do it real time via cellular uplink would be even better.
Good luck with your project. Phones can certainly handle it, but the problem lies with the providers - many block anything other than HTTP (especially WAP APNs). I'm uncertain whether this limitation exists on the "Internet" APNs that carriers are b…
I'll be watching your efforts intently - I am very interested in hooking stock cellphones up to MCU boards. I use bluetooth to connect between the phone and the board, then GPRS to connect to the remote server. One obstacle I ran into was that strea…
I've been occupying my time by writing some ground station software. I felt there was a need for a cross-platform solution, as not everyone can run the Labview GCS. I liked this but I decided to DIY it as a learning exercise. Like that program I am…
I wish. I bought a c168i off ebay but I found it didn't support AT command GPRS data over serial, and SMS is too expensive, too small, and too slow. In any case, I wanted to develop a relatively phone-agnostic solution so this was the only way. I de…
Any chance of a hard-wired serial link from the autopilot the cellphone? One generally tries to avoid adding more RF sources than necessary onboard.
The cellular link will eventually be able to issue commands but for now it is just telemetry. I'd appreciate suggestions on a command set for the base station. See my previous blog post for more details on the Google Earth live FPV simulator I inten…
What kind of UAV applications can you envision for this?
The emulator running some demo data, and showing the result.
The Bluetooth/GPRS application I've been working on is now functional enough that it might be of use to someone. Feedback and suggestions are appreciated. Currently, the application has b…
This post is about a live (simulated) FPV system using Google Earth, relaying data over a cellular GPRS/3G network. A while ago I saw a commercial OSD setup that used Google Earth to simulate an FPV display. Needless to say, I was immediately smitte…
I think they use a separate channel for the prop pitch. They call it "4D Flying" - it combines helicopter-like hovering and fixed-wing speed. The videos are pretty unreal - they can fly an inverted vertical climb! Take that, hummingbirds. Unfortunat…
I'm not an aerospace engineer, but didn't the SR-71 intakes increase compression because they reflected the supersonic shockwave?
I used to use a consumer GPS handheld on some of my projects and the user manual said if either of the two conditions…
Good point on HELIOS - I didn't know it went so high (but of course, $$$). I remember that one disintegrating in midair too though...
It's true that there is less air resistance up there, but there is also less thrust available for the prop. Are yo…
Sounds like a neat project, though I think your goals may be set a tad high unless your budget has 7 digits. I'd love to collaborate on UAV stuff, I'm in the general area. I'm just starting with UAVs but I have robotics experience.
I know someone wh…
Does anyone know if Bluetooth would interfere with the standard Spektrum-type 2.4GHz systems? I'm writing a JSR-82 app for telemetry transmission, since no phones with GPRS have serial ports anymore. I am worried about interference, however. If nece…
I'm a lurker but thought I'd share what I found today - hopefully it helps some people build better UAV's. I'm using cellular data too, but I am going the SSoftware2Mobile route. You can probably tell I kinda want to buy them anyways...

Bluetooth + GPRS Cellular Telemetry, Part II
The emulator running some demo data, and showing the result.
The Bluetooth/GPRS application I've been working on is now functional enough that it might be of use to someone. Feedback and suggestions are appreciated. Currently, the application has been left as a dumb bent pipe, so the… Continue

Google Earth Live FPV & Cellular Telemetry
This post is about a live (simulated) FPV system using Google Earth, relaying data over a cellular GPRS/3G network. A while ago I saw a commercial OSD setup that used Google Earth to simulate an FPV display. Needless to say, I was immediately smitten. However, video TX gear is expensive and a hassle, so Google Earth here serves as a simulated FPV. Hopefully this will eventually mature into a Google Earth HUD (like the Flight Sim easter egg already in it, but real-life!) Comments/Questions/Sugges… Continue
