I am having problems with my recently purchased mediatek GPS, i'm quite new to this so there is probably something obvious im doing wrong....
I have the mediatek GPS module and the adaptor bought as bought from the DIY drones store and the basic arupilot board and shield.I have been running through the debug options in the code (2.7) and all is well apart from the GPS.
I have installed the library folder "GPS_MTK" inside the Arduino IDE "libraries" folder "\arduino-00XX\libraries\\", and set the code to debug the gps output and monitoring through the serial monitor. The monitor keeps returning "no gps, last 10s" and the blue led on the gps board and shield is still flashing. I have had the gps outside for the best part of an hour and its still the same.
Any ideas?

I had another test with the APM + MTK today and had some problems. I don't know if anybody has experienced the same but I get a lock inside at home on the window board usually within several minutes (but also sometimes it takes 30min or so). However, I'm unable to get a lock outside! This is after waiting for longer than 30 minutes and on two different days (one cloudy, the other one clear sky). The GPS has clear view of the sky.
Here my wild guess: could it be that the temperature affects the battery on the adapter board? We now have around 3-4 degrees Celsius (around 38 degrees Fahrenheit) and the first time it was not much warmer than that.
Is there a way to use the GPS without the battery?

but with my iphone I get my location to be 51.481020 N 2.431370 W which I know is correct.
Any ideas?
Today, after uploading the APM beta code, my GPS simply blinks on and off slowly. My APM and Oilpan are connected to my PC via USB. I am using the test -> gps in the serial monitor.
It's been sat outside with a near 360° view of the sky for around half an hour now...
Perhaps I am doing something dumb.
Any thoughts appreciated.
Thanks in advance,

Check Vcc on the GPS module itself (not the 5v into the adapter). I'm going to guess that your Vcc is less than the spec of 3.2v.
