Data Compression for Bandwidth Constrained Environments

Progeny Systems envisions a robust ship-to-shore communication capability that adds superior compression, allowing for all of today"s and tomorrow"s diagnostic data transport needs to be accommodated using existing shipboard hardware and operating doctrines. Our approach will allow for very efficient lossless compression or even more efficient lossy compression. We will also allow for optimized selective application of both techniques within a given data set, providing the benefits of 100% retention of data where required, while minimizing the bandwidth for subsets of data that are less sensitive. Lastly, we will provide the ability to select sampling rates slower than the native rate, or at a variable rate designed to capture relevant, high rate changes while reducing the size required to describe slow or insignificant changes. The software approach we advocate will analyze the data and make recommendations to the operator to minimize or eliminate the human workload in selecting effective settings. Through these techniques we will enable operators to easily prepare data sets requiring a tiny fraction of the size required using today"s technologies.
