To apply the knowledge in hardware and software integration, as well as utilizing the NI LabVIEW and NI myDAQ signal acquisition attribute. The aim of this research paper is to provide a solution for determining the type of land topograhy through the detection of incoming multiple groundwave signals from different oscillation sources. Aside from source determination and notification, the user will also be able to visualize, analyze, and classify the type of the incoming signal which depends upon its response as it passes through an indefinite terrain. The system will be using Low Frequency (LF) ground-wave oscillations. This paper deals with the concern using the finite-difference time-domain (FDTD) of topographic terrain identification through soil conductivity and creating a virtual instrument (vi) that will execute a determination algorithm. The LabVIEW program that will be implemented is multiplatform, it will be able to support different versions of LabVIEW depending on the program availability and to support real-time targets

“…In fact, the Telemetry is a highly automated communications process, by which measurements are made and other data collected at remote points and transmitted to receiving equipment for monitoring. The satellite Telemetry is responsible for: (1) Acquiring the Telemetry sensors' data according to the applied measuring program which contains a set of sensors' addresses to be read, (2) Encapsulating the gathered data into the format of: Consultative Committee for Space Data Systems (CCSDS) [3] Several implementations of the state-of-the-art Telemetry have served different areas in the last few years such as: solar challenge applications [5]; signal processing applications [6], [7]; medical applications [8] and space applications [9], [10], [11]. All previously published Telemetry designs in space applications have not been modeled or tested using Checkout and Testing Equipment (CTE) based on LabVIEW.…”

Telemetry is an essential subsystem in Low Earth Orbit (LEO) Remote-Sensing satellites, as it is responsible for gathering satellite housekeeping data from all satellite subsystems, malfunction detection, performance evaluation and statistics. In this paper, a novel Checkout-and-Testing-Equipment (CTE) is proposed which simulates the Telemetry interfaces to other satellite subsystems and the Telemetry inputs such as: satellite sensors, and tests the full functionality of the Telemetry software/hardware. Besides, this work models the Telemetry data-acquisition core (Sensors Commutators) using LabVIEW. This new CTE is designed and implemented using LabVIEW and verified using National Instruments (NI) modules such as: NI Virtual Instrument Software Architecture (VISA), NI PXI-6509, NI PXI-6723 and NI PXI-4110. The Telemetry software framework is developed using the Integrated Development Environment (IDE) of C8051f120 Silicon Labs microcontroller.
