?
What does the GINA consist of and what inputs does
it provide to its associated flight instruments?
ANSWER:
1.
The GINA consists of a self contained, all attitude, world
wide, strapdown inertial system with an embedded GPS
receiver and a GPS (FRPA-3) antenna.
2.
The GINA provides vertical velocity, position, heading,
digital and analog attitude (pitch and roll) and time to the
DEU for the ADI, HSI and HUD displays, over the MIL-STD-
1553B MUX BUS.
