Gyroscopy

The JSC Medicon has successfully manufactured a small-size resonator (projects №№ 138 and 138V of the International Science and Technology Center, Moscow, 1995-1999) and correspondingly a small-size HRG for civil application.

The combination of high precision, low price and small size enables HRG enter new application areas in the markets with middle precision/price which were inaccessible earlier.

HRG advantages:
Small sizes ∅ 40 mm Low power consumption 1.2 W High vibration resistance of mechanic part (at 5 — 200 Hz) 60 g High shock-resistance of resonator (at impulse duration 0.15 ms) 4600 g No temperature control required   Short readiness time 5 sec Long life time 15 years Inertial qualities remain at power supply off 5-10 sec No influence from electromagnetic or radiation interference

		Parameters of castellation-free resonator defining precision performance of HRG:
		Operational frequency 8 kHz Diameter ∅ 30 mm Height 32 mm Q-factor 1.5 * 107 △F < 0.005 Hz Rest disbalance at all modes < 30 mkg

АRS (Angular Rate Sensor) parameters based on HRG:
Random drift component 0.1°/h Maximum measured speed 5°/sec Power consumption 1.5 W Weight of sensor mechanic part 160 g
