A new approach to mission operations will be flight validated on NASA’s New Millennium Program Deep Space One (DS1) mission scheduled to launch in October of 1998. The beacon monitor technology is an operational concept for reducing deep space mission operations cost and decreasing the loading on ground antennas. The technology is required for upcoming NASA missions to Pluto and Europa. With be...

In this paper we propose an approach to solving the problems of forecasting multivariate time series telemetry data that describe the state of small airborne objects. The main objective of the proposed method it's automated design and development of neural network models for solving such problems, namely the choice of model parameters are close to optimal. The approach is based on the use of en...

This talk describes a fully integrated neural recording IC with on-the-fly spike sorting and wireless telemetry. The chip consists of eight 16channel front-end blocks each consisting of amplifiers, multiplexer and ADC, data serializing circuits, DSP for on-the-fly spike sorting, digital MUX, encoder, UWB transmitter, and on-chip bias generators. The analog front end is programmable for gain, lo...

As spacecraft send back increasing amounts of telemetry data, improved anomaly detection systems are needed to lessen the monitoring burden placed on operations engineers and reduce operational risk. Current spacecraft monitoring systems only target a subset of anomaly types and often require costly expert knowledge to develop and maintain due to challenges involving scale and complexity. We de...

State estimation is necessary in diagnosing anomalies in Water Demand Systems (WDS). In this paper we present a neural network performing such a task. State estimation is performed by using optimization, which tries to reconcile all the available information. Quantification of the uncertainty of the input data (telemetry measures and demand predictions) can be achieved by means of robust estate...

We present the design, testing, and evaluation of a 16 channel wearable telemetry system to facilitate multichannel single unit recordings from freely moving test subjects. Our design is comprised of (1) a 16-channel analog front end board to condition and sample signals derived from implanted neural electrodes, (2) a digital board for processing and buffering the digitized waveforms, and (3) a...

When dealing with remote systems, it is desirable that these systems are capable of operation within acceptable levels with minimal control and maintenance. In terms or transmission of telemetry information, a prediction-based compression scheme has been introduced. This paper studies the influence of some typical transmission and network errors on the encoded residue stream produced by a numbe...

Cochlear implant programming necessitates accurate setting of programming levels, including maximum stimulation levels, of all active electrodes. Frequently, clinical techniques are adequate for setting these levels; however, they are sometimes insufficient (e.g., very young children). In the Nucleus 24, several methods have been suggested for estimation of comfort levels (C levels) from neural...
