New ▼ VG SOLID-STATE VERTICAL GYRO ▼ Roll and Pitch Angle Measurement in High Dynamic Environments ▼ High Stability MEMS Sensors ▼ High Range Gyro and Accel Options ▼ Enhanced Performance Using Kalman Filter Algorithm ▼ EMI & Vibration Resistant Applications ▼ UAV Control VG400CC ▼ Platform Stabilization ▼ Avionics The VG400CC is a high performance, solid-state vertical gyro intended for airborne applications such as UAV control, Avionics, and Platform Stabilization. This high reliability, strap-down inertial system provides attitude measurement with static and dynamic accuracy that exceeds traditional spinning mass vertical gyros. The VG400CC achieves its excellent performance by employing proprietary Kalman Filter algorithms to determine stabilized roll and pitch angles in static and dynamic conditions. The Kalman Filter implementation results in a continuous on-line gyro bias calibration, and an adaptive attitude measurement that is stabilized by the long term gravity reference. Output data is provided in both analog and digital (RS-232) formats. This VG400CC series product builds on the performance of the VG400CB series. It features higher performance sensors, including new silicon MEMS gyroscopes with wider bandwidth and Each Inertial System comes with a improved bias stability. New design User’s Manual offering helpful hints features in the VG400CC Series reduce on programming, installation, and sensitivity to vibration and EMI. product information. In addition, Crossbow’s GYRO-VIEW software is included to assist you in system development and evaluation, and allows you to perform data acquisition. inertial systems ▼ ▼ 64 Document Part Number: 6020-0022-01 c r o s s b o w t e c h n o l o g y, i n c ▼ 41 daggett drive ▼ san jose, ca 95134-2109 C VG400CC-100 VG400CC-200 Physical Size > 75 <1 < 60 Continuous Update Mode 15 Pin "D" Connector Male Pinout Under static conditions 1 ± 180, ± 90 ± 0.5 2.0 < 0.1 ± 180, ± 90 ± 1.0 2.5 < 0.1 3 10 Pin ±2 <± 8.5 <1 <1 < 0.25 > 25 < 0.1 ± 10 <± 12 <1 <1 < 1.25 > 25 < 0.5 -40 to +71 -55 to +85 6 1000 -40 to +71 -55 to +85 6 1000 20 Hz - 2 KHz random 1 ms half sine wave 9 to 30 < 250 <3 RS-232 ± 4.096 0 to 5.0 9 to 30 < 250 <3 RS-232 ± 4.096 0 to 5.0 at 12 VDC See “Digital Data Format” Pins 8, 9, 10, 12, 13, 14 Pins 5, 6, 7 Scaled sensor mode Angle mode -3 dB point Typical -3 dB point 3.0 x 3.75 x 3.2 3.0 x 3.75 x 3.2 7.62 x 9.53 x 8.13 7.62 x 9.53 x 8.13 < 1.4 < 1.4 < 0.64 < 0.64 15 pin sub-miniature “D” male 4 11 5 12 6 13 7 14 8 15 Signal 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 ± 200 <± 1.0 <± 0.05 <1 < 0.3 < 0.05 > 10 < 4.5 Connector 2 9 ± 100 <± 1.0 <± 0.05 <1 < 0.3 < 0.025 > 10 < 2.25 (in) (cm) (lbs) (kg) Weight > 75 <1 < 60 Remarks RS-232 Transmit Data RS-232 Receive Data Input Power Ground X-axis accel voltage1 Y-axis accel voltage1 Z-axis accel voltage1 Roll-axis angular rate2 Pitch-axis angular rate2 Yaw-axis angular rate2 NC – Factory use only Roll angle/X-axis acceleration3 Pitch angle/Y-axis acceleration3 Not used/Z-axis acceleration3 NC – Factory use only Notes 1 The accelerometer voltage outputs are taken directly from the accelerometers without compensation or scaling. 2 The angular rate analog outputs are scaled to represent degrees/second. Outputs are created by a D/A converter. 3 Actual output depends on VG measurement mode.
