mems-talk Dear MEMS friends: Now I want to do some research on MIMU(micromechanical inertial measurement unit). The first step is to establish the model of the MIMU(the product is IMU400CA-100 produced by Crossbow Company).The question is how can I determine the gyro drift model.The other is that I see a paper collected by IEEE which introduce a software named GINI can do some simulation about GPS-INS(MIMU).It is a commercial software desighed by Donald T.Knight.Where can I buy the software? Please give me some information about it. Thanks in advance. Teng Jitao ITS center of BUAA
