Hello,

I have uBlox 6M GPS on my Ardu 2.6, unfortunately the external GPS doesn't came with any instructional manual, so i m little confused about the GPS fix color code on LED.

once you power up the board the Green LED on GPS is lit constantly, later on the blue LED blinks. How do i know i have GPS fix so that i can fly my multirotor in loiter (GPS hold) mode.

Attaching the GPS pic for the reference.

thanks in advance.

Regards

Solid Green LED on GPS module--> GPS is ON
Flashing Blue LED on GPS module--> GPS Lock
Solid Blue LED on APM--> GPS Lock

You can check in Mission Planner about GPS lock status & no.of satellites.

thanks a lot
