"its work for me , horayy.... , thanks sebastian boehm, ardupilot gps lock (blue led) but in arduimu blue led still flashing , it is normal ? i use arduimu+V3 with EM-411 "

"same problem with my quadrocopter : corrections to the gimball axis are not sufficiently effective"

"Hello Jason is it possible to increase ardupilot speed correction of  gimball servos( my servos are0,06 deg/sec ) because when i moved rapidly my quad like in flight the gimball compensate too slowly i see big  image…"

"Yes. (All this is in the manual) "

"inside the ardupilot config tool software ?"

"You set any altitude you want in the config utility."

"the problem was, that the em406 code initializes the GPS with 57600, but ardupilot assumes that the arduimu runs with 38400. so either change the em406 code in arduimu to initialize the gps with 38400 or change ardupilot to connect to arduimu with…"

"So what did you change to get it to work?"

"so I finally got it…"

"ups... it is supposed to look like this, not an error."

"here are my oberservations: I changed the code in GPS_EM406 to just output every byte it receives from the GPS: ------------- if(Serial.available() > 0)//Ok, let me see, the buffer is empty? { Serial.println("***** there is someting…"

"As Doug mentioned, we don't support the EM406 for ArduIMU yet--it's designed for the uBlox, but we'll add other GPS modules over time. The code is in there but it hasn't been debugged yet, and it looks like there is something not…"

"ok , confirm red led on gps module remain off , i have uploaded the em406 tester code in the ardupilot with the em406 directly connected on it , blue light remain on and serial monitor window show gps position informations but with the gps module…"

"The code for the EM406 had not yet been debugged for use with ArduIMU. There are a few people trying it out now, but sounds like there are still some issues to be resolved."

"anyone has tested em406 with arduimu ? I have it working directly with the ardupilot, but it does now work wirh the arduimu. I am new to the project an it is difficult for me to debug this."
