1. A self-calibration electric pointing device, comprising:
- a sensors/actuator assembly wherein further comprises;
a 2-axis DTG (Dynamically Tuned Gyro) for sensing the earth rate and said device angular motion;
a first accelerometer;
a second accelerometer with said first accelerometer for sensing gravity; and
an indexing device carrying said 2-axis DTG, said first accelerometer, and said second accelerometer for real-time multiple position sensor calibration, wherein said indexing device moves said 2-axis DTG, said first accelerometer, and said second accelerometer when said system is starting or during said system operation for sensor calibration, wherein said sensor calibration is a two-position calibration that said indexing device only needs to stop at two points from an original point to a stop point to complete said sensor calibration;
a sensor interface circuits; and
a computation platform electrically connected with said sensors/actuator assembly by said sensor interface circuits for processing measurement from said sensors/actuator assembly for pointing.

Abstract
An innovative configuration of Miniaturized Smart Self-calibration EPD for mortar applications, as the azimuth/heading and elevation measurement device. This innovative EPD configuration uses only two FOGs or DTG and accelerometers and it is self-contained. This leads to a new EPD implementation that produces a small and light device with lower cost and adequate accuracy for the small dismounted mortar applications.
