The solid state angular rate transducer (START) is a gyro dependent for its operation on the rotation sensing properties of a resonant shell. A complete gyro requires both a resonant element (the cylinder) and a means of maintaining and measuring the vibration pattern about it. START uses a small electronic module for these vibration control purposes and to provide a usable interface to the user systems. The START Gyro is capable of withstanding the high shock environment of precision guided munitions (PGM). Successfully shock tested at 25,000g on a 155mm artillery shell trials range, this low cost device was developed for short time of flight applications including precision guided munitions, terminally guided submunitions, hypervelocity missiles and light anti-armour weapons. However the device has since seen application in active suspension systems in cars where its low cost and extreme ruggedness is ideal. It is simple to produce and therefore ideally suited to inexpensive mass production techniques.
In addition START offers significant advantages in terms of small size, light weight, instantaneous start and very low power. Alone or in a 3-axis configuration it competes successfully against current, more conventional technologies.
In 1990 GEC Avionics Guidance Systems Division were a finalist in the Prince of Wales Award for Innovation with the START Gyro. This is a pre-production device but has no markings.
