Data Logger with Satellite Transmitter for INSAT-3C
Overview
The Data Logger system provides a data logging from 24 analog, 8 digital and two SDI-12 inputs. First, the data is logged for 30 minutes, afterwards the results are transmitted to the satellite (INSAT and INSAT-3C). The GNSS-synchronized RTC is used for TDMA implementation. This allows installation of 1,800 systems using the same carrier. The system is based on the NI sbRIO platform, which handles all the processing.
The key tools that are used in the developed system are: NI LabVIEW, NI LabVIEW Real-Time Module and the LabVIEW FPGA Module, which is one of the most powerful FPGA programming tools available.
The software has a user-friendly menu interface for configuration and settings of data transmission parameters, such as frequency, signal power, transmit time, etc.
