The following report deals with the development of a rate table at GIKI for the purpose of testing MEMS-based gyroscopes being developed here. This report consists of the initial study done by the team in this field of science. Rate tables have been studied in detail and knowledge about commercially available rate tables has been included too. The report discusses the objective of the project and problem statement. It contains the solution to obtaining output from the gyroscope during the rotational motion being performed. It also contains other technical issues and choice of hardware. Specifications of the different equipment used have been also added. The Pro-E design is also been included. Furthermore, suggestions for further improvement in the current design have also been mentioned.

Chapter 3 Design
The graduate students at GIKI have worked on the development of MEMS-based gyroscopes. For this purpose a rate table was required for the MEMS lab in order to test these gyroscopes. Hence this task was undertaken at undergraduate level in the form of a final year project. The purpose of this was to create technical awareness of MEMS technology at an undergraduate level plus achieve the required goal in a very cost effective manner. Problem Definition
The task was to indigenously develop a rate table which not only is cost-effective but also delivers performance parameters. Aim
The aim was to design a single-axis rate table. On the top of the rate table, IC (gyroscope) shall be mounted. From a PC through a controller, the rate table shall be rotated at the required rate (rpm). All the connections to the IC shall be available through the non-rotating base of the table. Time line

Introduction to Rate Table
Rate table is a device which is widely used for testing and calibrating instruments such as precision gyros and accelerometers which comprise the basic sensors in high-accuracy inertial guidance systems. Because...
