ER-FNS-03 Low Cost 3 Axis FOG North Seeker

2.1 Acceleration sensor

2.1 .1 Accelerometer Head

The accelerometer uses a quartz flexible accelerometer. The metering works under the condition of no temperature control, and a temperature sensor is mounted on the metering shell to perform temperature compensation for the metering.

The requirements for the main performance and technical indicators of the accelerometer are shown in Table 3.

Table 3 Main technical indicators of accelerometer components

NoNameValue range
1Measuring range±15g
2Bias stability≤2×10-4g
3Bias Repeatability≤2×10-4g
4Scale coefficient nonlinear≤100ppm

2.1 .2 Interface Protocol

The data output adopts RS422 mode. The navigation board controls data synchronization. The RS422 communication protocol is: 1 (start bit), 8 (data bit), 1 (check bit), 1 (stop bit); baud rate 614400bps, data update The rate is 400Hz. The specific frame format is shown in Table 4.
