Integrated Time-Ordered Data Trending and Performance Evaluation Tools
An integrated sensor test, or more generally any test that collects
time-ordered system health and status data over an extended duration,
requires a managed approach to data storage and retrieval. Careful
analysis of telemetry data (i.e. temperatures, pressures, voltages,
currents, etc.) coming from the unit under test and/or its related test
equipment is essential to predicting nominal behavior as well as
understanding and rectifying anomalies or problematic trends. FTI has
drawn on many years of experience in the field of space-based sensor
calibration to develop the TelemTrend® Software Package. TelemTrend® is a
database-enabled, C++-based application that allows the user to plot
and analyze time-ordered telemetry data. Additionally, TelemTrend®
incorporates many proprietary algorithms that permit a deeper analysis
and a richer understanding of features (spikes, trends, etc.) in the
data. This product has a proven track record and continues to save our
customers analysis time and program money.
Historically, large science programs collect an enormous amount of
corollary telemetry data. Apart from performance data, telemetry data
types such as environmental conditions (component temperatures, chamber
pressures, etc.), control parameters (command settings, alarms, etc.)
and system measurables (impedance, power draw, etc.) are often stored
as a matter of course. In the event that telemetry needs to be
revisited however, the method is usually a painful and time-consuming
data mining process through countless separate log files culminated by
manual collation in a generic program such as Excel® or MATLAB®
software. This method is both inefficient and prone to mistakes.
Additionally, applying filters or constraints in order to condition
data for meaningful display is, again, a manual process and subject to
the same disadvantages. FTI has developed TelemTrend® to address its
customers’ needs for robust telemetry data management and rapid
display.
