Design of Master Data Acquisition Module for Data Acquisition and Telemetry Operations

C. H. Sanjay, Satyanarayana Kumari B., and Kasetty Ram Babu

Abstract—The paper describes Design of Master Data Acquisition module which is used for analog data acquisition from various sensors in satellite subsystems and also performs generation of different telecommands for telemetry operation. Data Acquisition plays an important role in monitoring the health parameters of the satellite. The embedded software was designed to receive input from various sensors and down linked to the Command and Data Acquisition (CDA) Station and sent to the Satellite Operations Control Center (SOCC) and initiate corrective action form earth control station when required. This methodology was not compromised with respect to the application and execution time. The advent of Field Programmable Gate Arrays (FPGAs) has made compact realization of embedded system possible. As FPGAs are high density logic devices. It is possible to realize certain software functions in hardware in an efficient way. In this paper it is an approach of designing Data Acquisition in Hardware, an input multiplexer is used to route data from various sensors. The selection of channel in the multiplexer, generation of control signal and data reading is performed by Master Data Acquisition module. Entire Design is carried out using Very High Speed Integrated circuit (VHSIC) Hardware Description Language.

Index Terms—Data acquisition, data converters, telemetry, bus management unit.
