We design a portable measurement device which can monitor electrocardiograph (ECG) and analyze arrhythmia. It is small, light, lower power, and consists of two parts: the main system and the sub. The device gets ECG signals by the electrode sticking to the chest skin. This make the device is suitable for monitoring in long time. 16-bits MCU-MSP430 is the(More)
The integration of Inertial Navigation System (INS) and Global Positioning System (GPS) is a most frequent method for land navigation. Conventional Kalman Filter (CKF) is an optimal estimation algorithm widely used in INS/GPS integration. CKF assumes that the covariance of the system process noise and measurement noise are given and constant. The(More)
