Antennas Connection
Each antenna is connected to some JNSGyro-4T board. The boards are
connected to each other through the serial ports as shown in Figure 3-4.
The first board is referred to as Master . The other three boards (2nd, 3rd,
and 4th) are called Slaves .
Master sends raw data to Slaves . They process the data and send results
back to Master . It processes the results and calculates the attitude. To
provide data exchange between the boards, they are interconnected as
shown in Figure 3-4.

corrections to Master , the following GRIL commands must be sent to
Slave2 :
