The choice of output mode; analogue or digital, is determined by the user when connecting it to the user’s host PCBA; details of the electrical interface between PinPoint® and the host PCBA are given in Section 7. PinPoint® is available in several configurations; a) CRM100 which measures angular velocity about an axis perpendicular to the plane of the host PCBA, referred to as ‘in-plane’ sensing, b) CRM200 which measures angular velocity about an axis which is parallel to the plane of the host PCBA, referred to as ‘orthogonal’ sensing and c) CRM102 and CRM202 which are capable of measuring angular velocities in excess of ±2700°/s. With a combination of CRM100 and CRM200 it is possible for the user to measure angular rate of multiple axes (e.g. any combination of pitch, yaw and roll) from a single host PCBA. PinPoint® is supplied as a PCBA surface mountable LCC ceramic packaged device. It comprises five main components; silicon MEMS ring Sensor, Pedestal, ASIC, Package Base and Lid. More details of the construction are given in Section 13. There are eight actuators / transducers distributed evenly around the perimeter of the silicon MEMS ring. Located about its primary axes are a single pair of ‘primary drive’ actuators and a single pair of ‘primary pick-off’ transducers. Located about its secondary axes (at 45° to the primary) are two pairs of ‘secondary pick-off’ transducers see Figure 1.1. The ‘primary drive’ actuators and ‘primary pick-off’ transducers act together in a closed-loop system to excite and control the ring primary operating vibration amplitude and frequency. Secondary ‘pick-off’ transducers detect radial movement at the secondary axes, the magnitude of which is proportional to the angular speed of rotation and from which the gyro derives angular rate.
