"All:
I have been testing a LEO-6P with active antenna for better positioning accuracy. Strange effects you should be aware of : using ublox ucenter software this setup gives me HDOP 0.9 to1.1 indoors !. However when connected to APM2.5, MP shows hdo…"

"@All especially TCIII:
I too am having dififculty getting 2.30_2013_0222 to compile. I get an error from the compiler complaining about s.calibrate_accel  function with error .. no matching funtion for call to "AP_InertialSensor_MPU6000 ...
I have n…"

"@TCIII:
The ublox active antenna has a metal base ground plane plate in it. My understanding is that you need to isolate it from the chassis but I will investigate this further. Every little bit of GPS precision helps !

"Hello All:
I have been able to get the ublox LEA-6P GPS to talk to the rover APM. This thing is supposed use PPP (whatever that is) to get better position accuracy for slow moving vehicles. Also, it has a SMA connnectors for an external active anten…"

"IMHO driving a twin screw boat should not be much different than a differential drive rover. Just use a mixer to convert the steering+throttle input from the APM to left and right drive signals. You can easily program a Arduino UNO ($29) to do this.…"

Go to ublox site - > Resources and Docs -> Tutorials - > GPS Compendium
 
It's a long read but very well done. If you are going to use GPS you must read this - the you will understand why having multiple GPS receivers does not really improve…"

"Go to the ublox website. They have and excellent article on GPS - history, theory, limitatations and future. It appears that having two GPS units does not solve much, but next year there will be new satellites that will transmit on two different fre…"
