Well, to be honest…you can’t stop anywhere ? Catching Pokémon isn’t that easy doing it this way ? This still needs some code to improve it.Getting started with Software Defined Radio (SDR) has never been easier thanks to GNU Radio and the various SDRs available. Starting the transmission again, you’ll find your avatar walking around on your own route ? After compiling, just follow the instructions in the readme file.

In the “satgen” called folder of GPS-SDR-SIM is another application, which could be compiled with the same settings as the main app itself. So, prepare for the next step: Plotting routes. Now, just start Pokémon GO and see your avatar walking/standing around in the wild.īut…this is boring, isn’t it? Just anywhere…not where you wanted to be? While using a GPS app on your phone, you could also delete your A-GPS data if supported by the app. Don’t know, what I’m talking about? Either go in flight mode or disable in your phone’s location settings the use of the mobile network and WIFI/BT. A few minutes later I’ve got a fix on all of my devices.Ī hint from my side: This works much better, if you disable the A-GPS (Assisted GPS) features of your device. Starting the transmission again, the fake satellites immediately came up with a strong signal (you should use attenuators to weaken the signal and also keep in mind local law!).

If you’re the DIY-/hacker-type of cheater, you’ll also find some gerbers in GPS-SDR-SIMs “extclk”-folder ?Īs I had no TCXO lying around, I made use of our function generator and set up a 10MHz square wave signal with 3Vpp. There are already some parts available in online shops, which were designed for the HackRf. Mostly this option makes use of a TCXO, which is a temperature compensated oscillator and has a precision of +/- 1 or 2.5ppm. The second option, and also my preferred one, is to use an external clock that is much more precise than the internal one. I didn’t give it a try, yet – but I hope this will work for you, guys. As the master branch of HackRF on Github currently doesn’t support a ppm correction, there is already a pull request, which adds the option “-C” for error correction rate. The first is, to use kalibrate-hackrf, which uses the frequency correction channel (FCCH) of the GSM network to calculate an average error in ppm (parts per million). This means, it isn’t as precise as needed by GPS and that is, why the HackRF acted like a jammer, not faking satellites here. I’ve already reckoned on this, as the HackRF’s internal clock (~30ppm) is much too vague. Before transmitting, I received a few satellites in my lab when transmission was started, the phones lost contact to every satellite’s signal.

I’ve used some phones running Android to check the GPS signal with some GPS test app. You just have to follow the instructions in the readme to make it work.īy setting up the HackRF in transfer mode, I initially “jammed” the whole GPS L1 band. Way off the mark! The tool compiled quite well on my machine and really works like a charm. After asking uncle Google, I came across “GPS-SDR-SIM” by Takuji Ebinuma and to be honest I didn’t expect a working tool. I already knew that there was some tool in the wild since last year. Okay, now that you’ve all read and understood this, back to our technical topic!

WARNING: In most countries transmitting on these frequencies is prohibited by law! As satellite’s GPS signals are very weak while receiving on earth, transmitted signals with the HackRF will be very strong in comparison – use attenuators and/or shielding boxes, as GPS receivers of navigation systems are very sensitive! Don’t abuse this knowledge, it’s just a proof of concept! When I came to ERNW in 2014 I got in touch with Michael Ossman’s great HackRF One for the first time, and subsequently my thesis was based on SDR. In the past I was often fiddling around with SDR (Software Defined Radio), started with DVB-T sticks some years ago. The moment, when your team leader asks you to cheat at Pokémon GO…everyone knows it, right? No? Well, I do ? GPS Spoofing SetupĪs I’m not a gamer, the technical part was of much more interest – that’s the real gaming for me.
