Power requirements:

+ 5V A: + 5V ± 5%, 0.4A (transient peak about 1.5A), ripple less than 50mV

-5V A: -5V ± 5%, 100mA, ripple less than 50mV

VCC: + 5V ± 10% or + 3.3 V ± 10%,

Note: GND and AGND shall not be connected to the gyro housing.

 

Performance index:

1 Scale factor

Non-linearity of scale factor at room temperature: < 100 ppm

Normal temperature scale factor repeatability: < 100 ppm (1σ).

2 Zero-bias stability

Zero-bias stability at room temperature:

F50A: < 0.1 °/H (1σ) 10s smooth 1H test result

F50 B: < 0.2 °/H (1σ) 10s smooth 1H test result

3 Zero-bias repeatability

Normal-temperature zero-bias repeatability:

F50A: < 0.2 °/H (1σ) 6 test data calculation

F50 B: < 0.3 °/H (1σ) 6 test data calculation

Full temperature operating range:

F50A: < 0.5 °/H (full temperature extreme difference)

F50 B: < 0.6 °/H (full temperature limit difference)

 

4 Random walk

 Environmental adaptability:

3.1 Operating temperature

-45℃~+60℃

3.2 Storage temperature

-55℃~+75℃.

Impact

100g (11 ms), 3 times in a row, in three directions. Mean change of zero deviation before and after impact ≤ 0.5 °/H.

Vibration

(A) Randomly swept spectral lines:

20~80Hz :3dB/oct

80~350 Hz :0.04/Hz

350~2000Hz :-3dB/oct

(B) 3 minutes for each of the three directions, the gyroscope is in the working state during the vibration test, and the mean change of zero deviation before, during and after the vibration is ≤ 0.5 °/H.

 

 

 

 

Communication

When the standard RS-422 serial communication interface is used, the protocol can be adjusted as required.

Hardware interface: the baud rate is 614.4kbps. The communication format is 11 bits of data per frame, including 1start bit, 8 data bits, 1 even parity bit and 1stop bit. The data update period is 0.5ms.

Software communication protocol:

Gyro valid data is 32 bits (32-bit signed integer). The data packet transmits 7 bytes of data in total: the first byte is the frame header 80H; Bytes 2 to 6 are gyro data; The 7th byte is a check bit (the check bit is an exclusive or value of the data of the 2nd to 6th bytes).

Data format:

The first byte (frame header) is 80H:

 

10000000
 

The second byte is gyro data D6 ~ D0:

0D6D5D4D3D2D1D0
 

The third byte is gyro data D13 to D7:

0D13D12D11D10D9D8D7
 

The fourth byte is gyro data D20 ~ D14:

0D20D19D18D17D16D15D14
 

The 5th byte is gyro data D27 ~ D21:

0D27D26D25D24D23D22D21
 

The 6th byte is gyro data D31 ~ D28:

0000D31D30D29D28
 

The 7th byte (check bit) is the exclusive or (XOR) of the 2nd to 6th bytes of data.
