Abstract
A gyroscope erection system uses an electrolytic tilt transducer (21) to modulate oscillator signals (OSC, OSC) originating from a signal conditioning circuit (27). The signal conditioning circuit (27) receives the modulated oscillator signal and compares one unmodated oscillator signal with the modulated oscillator signal from the tilt transducer (21), to provide a demodulated signal. The demodulated signal is used to provide direction and amplitude signals to a pair of multipliers (45, 47). Output from the multipliers (45, 47) are amplified in order to drive a torquer (25).
