Caterpillar has for many years used telemetry as a key component in the data acquisition and analysis systems used to test and develop heavy equipment. The testing of construction and mining equipment at Caterpillar presents several unique challenges, such as the operating environment of the test machine, the large number of models in the product line, the need to change test machines on a dail...

The Serial Streaming Telemetry infrastructure is being augmented with the Telemetry Network System, which is a net-centric infrastructure requiring bi-directional communications between the test article segment and the ground station segment. As a result, future radio segments must implement transceiver architecture to support bi-directional communications. This paper presents a design methodol...

In this paper, we investigate high-capacity fiber-optic networks for real-time telemetry applications. The network topologies and related network components are analyzed for telemetry fiber-optic Local Area Network (LAN) and Metropolitan Area Network (MAN) as well as MAN internetworking with LANs. Two types of multiplexing techniques, namely, Wavelength Division Multiplexing and Time Division M...

Abstract Acoustic telemetry is widely used to investigate aquatic animal movement. Pulse position modulation (PPM) an acoustic method that allows multiple unique identification codes be transmitted at a single frequency, typically in the 69 kHz range. However, because potential number of (i.e. tags) ultimately limited by pulses PPM signal, this poses practical limitation. In addition, different...

This paper addresses the latest advancements in the application of computational electromagnetics and smart telemetry systems to the development of a retinal prosthesis to restore the sight in the blind. Numerical methods and models have been developed to a) accurately characterize the thermal increase in the human head and eye associated with the operation of the retinal prosthesis, b) determi...

Enclosed weapon bays on modern aircraft interfere with prelaunch, Flight Termination System verification during training test launches. Range safety personnel need to verify the functionality of the flight termination system prior to missile launch. The missile telemetry RF is highly attenuated when the aircraft missile bay doors are closed, limiting the range for which the aircraft can fly dur...

Binary Phase Shift Keying (BPSK) is a promising modulation format for downlink data transmission in inductive biomedical telemetry systems, because it achieves high data rates and power efficiencies and requires simple electronics. In this paper, the Bit Error Rate (BER) performance of a BPSK biomedical telemetry system is investigated under Additive White Gaussian Noise (AWGN) and is found to ...
