A Design of Temperature Measuring and Communication Software for SINS

The temperature measuring and communication software is designed to gather and filter multiple temperature data, guarantee the measuring precision in a wide temperature range. It can receive position and navigation data of GPS in real time, and transmit satellite data well and truly in the rapid time. In the software, an appropriate process flow is designed, the calculating of temperature data and the noise eliminating are accomplished using the method of mean glide filtering in combination with the arithmetic average; Based on circular queue technology, the serial data can be received in real-time. Application proves: the software has a repeatability precision higher than 0.05℃ in temperature measuring, can timely and accurately send navigation data to the fire control computer, and can meet the demand that receiving and handing ephemeris data of several KB in the 2s without data lose, therefore providing a way to realize temperature compensation, data fusion and external information interaction for LSINS.
