"The encoding looks like HH:MM:SS:ms(3) since SS increments on a 1000 count of ms and MM increments as SS reaches 60.
That also explains your plots periodic 60 seconds of data followed by 40 second 'jumps'.
Interesting that resolution only appears…"

"AP does not derive dynamic response from a static model of your airframe (nor will any other generic autopilot), so it doesn't ask you for static parameters. Reason? - there is no simple generic static>dynamic model offering good accuracy for all…"
"The voltage regulator only works for power supplied from the external battery input, which should be greater than 7.4V.
Feeding power from the receiver inputs you bypass the regulator - there is no regulation, and at 6.55V you are overvolting your…"

"If you mesh 4 gears like that you get 2 clockwise and 2 anti-clockwise drives while the drive motors both spin in the same direction."
"Prof,
There are fuse bits which should be set when a bootloader is used to prevent the bootloader memory space being overwritten. It sounds like these may not be set correctly in your case.
A guide to avr fuses is here. A google search will get…"

"Attached is a pre-alpha MediaTek parser for ArduIMU. Warning - this is as yet untested so don't fly it!!
For testing purposes only. Any feedback welcome.
I believe Earl also has some code...GPS_MTK.pde"

"ArduPilot Mega code is an autopilot for planes. Have a search for ArduCopter which is a controller for quads/helis based round the same hardware."
"Version 1.91b seems to be the most cooperative, based on feedback from the T3 round 6 thread and elsewhere. Are you configuring FG to accept packets at a higher rate than you actually feed, as that may be worth a go. Also do you set control surface…"
"Ken,
There doesn't look to be any code for EM406 in the mega libraries. You may get it to work in NMEA mode, but there is no specific initialisation code. You would need to do your own init to set the output to NMEA @38400."

""X-Plane actually binds two ports - 49000 and 49001. It uses 49000 only to receive data, and 49001 only to send data (this is the difference from previous versions - it used to use 49000 to transmit and receive). These are hard coded into X-Plane,…"
"Great work Tom!
Tom Y, can you tell if the delay is in the SciLab or Flightgear side? And are you using a TCP or UDP link?"

"You're most welcome, but Ken deserves the credit for that one. Cheers Ken!
All the best!"

"Jeff,
The third one should be the charm... (hopefully). Apparently binary mode configuration requires a different message format. DIYDrones' Ken has supplied code to reset to NMEA mode - here.
Attached below is Ken's reset code as a sketch. Run…"

"Jeff,
Find attached an updated version. The last had a possible error due to me coding/uploading in haste (was on my way out of the house and keeping my better half waiting), my apologies!

"Jeff,
Suspect you have hit the nail on the head. If have a lock with ArduPilot then the GPS is set for 57kbit/s binary mode, and those settings are retained until the onboard supercap discharges (up to a week).
The IMU initialisation code assumes…"

"The code updates were added to the official download a month or so back. Grab the official download from here (top one).
If you are still having issues post your configuration settings.
All the best!"
