  @Thomas

  Thank you and I'll let you know if it works!

  @Austin,

  How do you have your receiver connected to your APM1.4 and how are you powering your APM1.4? Are you using an Oilpan also?

  I am using split power rails on my APM1.4. The BEC in the rover ESC powers the APM output rails and a separate BEC powers the APM input rails and the receiver. You might take a look at the ArduRover Wiki http://rover.ardupilot.com/wiki/setup/ Here is the procedure to split the APM1.4 power rails: http://diydrones.com/profiles/blogs/simple-apm-2560-power-hack Also, don't forget to unsolder jumper S1.

  It sounds like your receiver is not getting power from the APM as you have indicated.

  @John,

  You might get between 1.5 to 3 ft accuracy depending on the weather, clouds tend to reduce the number of sats received, the surrounding physical environment, and just plain luck.

  Hello, 

  I'm using the APM 1.4 and I am having issues with my radio system. I am using a Spektrum dx6i and the transmitter doesn't seem to connect with the receiver. the light on the receiver doesn't flash at all and I suspect it may not be getting power for some reason. The receiver worked with the APM 2.5, connecting nearly every time, but with the 1.4 it just doesn't seem to  connect. Does anyone have any idea why this is?

  I just posted another question in my build thread, this time about MediaTek GPS accuracy.  Trying to figure out what the expected accuracy is an if I am causing my own problem with the way I have it setup.

  For those of you who would like to purchase a GoPro camera and don't need the pricey GoPro3, Costco has the GoPro2 outdoor version with the WiFi backpack for $199 USD. It is not shown on their website. I only saw it in the Costco in Davie, FL. Could be its a local special only.

  I've been using a Skytraq S1315RAW-EVK from www.skytraq.com along with RTKLIB from www.rtklib.com. I get NRTK corrections from a local service (Australia).

  @Mark,

  Tridge is working on integrating a L1 control process into the ArduRover2 code, but I do not know when he plans to compelet that effort.

  Also we have discussed using the optical flow sensor for accurate position measurement, but that will take using a PX4.

  You might want to start a discussion in the Discussion Forum titled "Improving the ArduRover positional accuracy and knowledge" or something like that so you have continuity of the discussion flow.

  Could you please point me to a source for the low-cost L1 capable GPS with NRTK corrections.

  Regards,

  Since he's using a uBlox, he can only go down so far. Since your GPS seems to be able to get 20cm accuracy, you're really the only one that can test whether a 0.1 m would work well as it will be difficult for any of us to test that out.
