Telemetry over cellular IP

Develop standard, re-usable inexpensive solutions for IP-enabled always-on UAVs over cellular IP networks such as GPRS, 3G, 4G etc.

Primary goal: Telemetry over low cost cellular [achieved in testing]

Secondary goal: Bi-directional GCS/Telemetry over cellular IP [achieved in testing]

Tertiary goal: High speed IP for streaming IP video over cellular 3G/4G

STATUS: Bi-directional telemetry over cellular IP (UDP or TCP) is now working. It has been flown successfully while logging live telemetry to a GCS at home, several miles away [distance is really unlimited]. Currently working on improving code, more testing and broader hardware support.

is this still updated? would want to know more especially how to run off multiwii

4Gmetry 4 is coming, stay tuned on

One of the time consuming tasks when integrating a Raspberry Pi or other SBC into a drone is making the power cable. Kashmir World Foundation has some great micro USB to DuPont power cables. You can get one by e-mail:

ok, thanks. Great!

Comment by Bill Piedra on January 14, 2016 at 8:25am

You would need a different telemetry cable - like this one:

Does it work with the APM 2.6 ?

NEW 2016 - 4Gmetry III - turnkey 4G telemetry over 4G, just plug&play.

Are you sure FAA has ever approved 2G/3G/4G telemetry in case of recreational drones ?

Parcel delivery is easy job.

2G/3G/4G telemetry is not reliable at all in case of drones.

Direct radio link between control station/pilot and the drone is the Basic Rule.

2/3/4G telemetry can come as add-on only, since in case

2/3/4G signal is lost, telemetry is lost and drone operator is starting to  violate standards set by FAA.

I have developed 3G modem to 3G modem- peer2peer

direct communication technology (dynamic IP assigned on both sides) without the need to run dynamic DNS server.

And this technology has now patent pending status.

It's a safety parameter to switch into manual mode just in case it starts to fly away. You can take off the failsafe for loss of radio link, although this is a drastic measure and I wouldn't recommend it. What products are you using

I just have a quick question regarding a behavior that I have experienced:

I have a quad with Pixhawk (3.2) connected to a custom cloud GCS through 3G/4G dongle. I have a 3DR radio that I use for pre-flight checks (arm/disarm/check motors etc) but I would like to fly without it.

Without the radio turned on the quad flipps out of control when i launch it. With the radio connected (just turned on, no inputs) it works perfect. For some reason the quad will not fly stable without the radio connected. I have disabled the GCS failsafe and the Throttle failsafe, I send the RC override from our GCS. 

Any ideas?
