dual GPS

[fberna]

hello,

I have been reading about the Phantom 4 having dual GPS capability.

Dual GPS in the professional/survey field is intended as the capability to use both L1 and L2 frequencies (1575.42 & 1227.60 MHz). This results in sub meter position accuracy.

The capability of using more positioning systems (Glonass, Galileo, CNSS) is often referred as dual system in the drone community, but it is not.

Also I would like to know if the Phantom does have two GPS receivers, the same way it uses two IMUs.

Does anyone know where to find detailed technical information/specs about the GPS and IMU of the Phantom?

thanks
Ferdinando

It has a dual mode GPS & GLONASS receiver. It's one chip that is able to use both the GPS and GLONASS satellites.

I have not come across the IMU specs but the GPS iengine is made by uBlox. NEO-8Q I believe or similar NEO variant.
