"Hello, could you tell me what the output format of the raw measurements is? Is it the proprietary Skytraq raw or RTCM 3.x format? If it is the Skytraq format, is there a protocol definition somewhere that might facilitate translation to RTCM 3.x?…"
"I briefly dug through your code and let me join the long list of others in congratulating you! I too have been working on this for quite some time and can say that all the time and effort will be well worth it the first time you see it fly by…"
"For what it's worth, I have that exact setup (Xbee+rangevideo) and it works fine. I have used it on both electric and gasoline powered airframes with no issues."
"Thanks to Bill et. al. I am finally contributing, not just withdrawing!

One hot-off-the-press propeller spin based DCM algorithm coming up! Admittedly it is quite simplistic…"

Well here it is, the first DCM propeller code (that I have seen). This is based on the wealth of work put forth by Bill Premerlani and others on the Ardupilot/matrix pilot side. I must admit that this is the first enormous coding project that I…
Has anyone had any luck measuring fuel flow or fuel volume in a glow fuel powered aircraft?I was contemplating using a differential pressure sensor to calculate the mass flow rate between the tank and the needle valve, but I have a hunch that the…
Hello all,I am trying to use a magnetometer as a reference vector for yaw drift cancellation in the direction cosine matrix. Ok, so here's the nuts and bolts. If I measure a three axis magnetic vector in the aircraft frame of reference, the…
"Hello all! I come to you humbly to discuss using magnetometers in the DCM algorithm. I believe that my questions will reflect my lack of understanding here! Currently I am working with the propeller chip and have successfully demonstrated pitch/roll…"
"AHHH HELP!!! OK, so I bought the ardupilot main board and the daughter boards to make a 6-dof monster. Currently, I am using the propeller chip and integer operations to get things up and going. Suffice to say that I have the bulk of the math in…"
"Soo, is there any consensus on the applicability of Sparkfun's 5 dof IMU as it applies to the DCM estimation routine? Are the gyros (IDG500's) excessively noisy/drifty?(I don't think 'drifty' is a word, but whatever, it sounds cool.) I was hoping to…"
"Hi all!
I have "Programmed" the DCM estimation algorithm in Matlab and seem to understand how it is working. The next step I am taking is translating it to the Propeller chip. Using floating point operations and the full renormalization scheme, I…"

"So I believe the title of this post aptly applies to me!! I pirated your code and matlab'ed it and let me say, WOW! So, what's the next step from here? I suppose that it is not as simple as running two independent loops for pitch and roll. Any…"
