- Manufacturing and testing of MEMS IMU
(2003 - pres.).
IMU costs $ 300 - $ 500 and has errors less (20-30)
cm without GPS per (5-20) sec.
- The monitoring system of a contact network of
(2003 - pres.).
The sample of system is made and tested.
- Road departure warning system for light
(2001 - pres.).
Develop technologies and create a prototype of the
Vehicle Road Departure Warning System based on MEMS IMU & GPS and
cost s $300 - $500. RDWS warns the driver of a possible departure of the
vehicle from the road in 3 to 5 seconds based on a measurement of the
vehicle's position with respect to the road at the accuracy (RMS) 20 cm
- Development of a Strapdown Attitude and Heading Reference
System on the basis fiber optical gyros (FOG) with Global Position
System (GPS) complexion for airplane of local airlines
(1999 - pres.).
AHRS characteristics: Heading - 0.5 grad, Roll - 0.1 grad, Pitch
- 0.1 grad, mass -up to 4 kg. The Kalman filter
is used for integration INS and GPS.
- Development of Strapdown Inertial Navigation Equipment for
the Land Vehicles
The error SINS for vehicle
at stops in 10 minutes does not exceed (12-20) m (during activity) and
(5 - 10) m (after activity of a system).
- Development of the Strapdown Heading and Attitude
Reference System Based on Dynamic-Tuned Gyros for
(1992 - 1994).
The experimental sample of a system is made and
the alpha tests are conducted. The system had an error: Half gyrocompass
Heading - 0.5 grad/h.
- Development of Software of Failure-Tolerant
Not threshold method and algorithm of detection and
localization of refusals in SINS with an abundant number of gyroscopes
deciding a problem of localization of refusals for want of large
relation noise / signal is developed. For want of it the error
accumulated during from a moment of origin up to localization of a
refusal does not exceed 28 angular seconds irrespective of a level of a
- Study of Mutual Influence of Dithers of Laser
(1995 - 1996).
The mathematical model of the
phenomenon is developed, are obtained the cycle of
experiments is conducted and researches on the COMPUTER (the close
outcomes), are developed the recommendations after change of a design of
the unit of sensors and system of amortization, that has
allowed to reduce effect up to size less than 1 %.
Recommendation as to reducing the mutual influence.
- Development and
Study of Methods of SINS Autonomous Calibration (1994
The method standalone Calibration backing uniformly precise
SINS, permitting without engaging the external information is developed to
evaluate and to compensate drifts of gyroscopes with an error - (0.005-0.01)
deg/h, scale coefficients of gyroscopes - (0.3-0.6)x10-5 , scale
coefficients of accelerometers - (0.2-0.8)x10-4 , corners of mutual orientation
of gyroscopes and accelerometers - (1-3) Arcsec.
- Development of Methods of and Hardware for SINS
(1992 - 1994).
high-accuracy SINS calibration using low-accuracy equipment. (error of
rotary desktop - 1 angular minute). The experiments have confirmed
effectiveness of an offered method and software.
