PS Input

Instructions: This shows the output from the GPS module, which should be plugged in the GPS port on the APM board. Typically, it will only be meaningful if you're outdoors, with a clear view of the sky. Some GPS modules will get sat lock indoors if you're in a wooden house without too many floors between you and the sky, but it's very unpredictable. Typically GPS modules require as much as 15 minutes to get sat lock if they're "cold starting", which is to say they haven't been powered on for a day or more.

Troubleshooting: If you're outside and have given the module time (at least 15 minutes) to get sat lock, causes for no data can include:

• If you're using the !MediaTek GPS module, you need to reset the APM board after powering on, so the configuration string is properly sent. We'll fix this in the code, but for now, just hit the reset button before testing the GPS.
• Are you sure you plugged the GPS into to the APM board, and not the similar connector (which says "NO GPS!") on the IMU shield?
• Problem with the cable (check to make sure the pins in the connector aren't bent)
• Corrupt GPS firmware. Instructions for reloading the firmware are here: uBlox, MediaTek
• You're using a GPS module not currently supported. At present, only the DIY Drones uBlox and !MediaTek modules are supported
