Positive Train Control (PTC) has placed a premium on communications and signaling testing, as microprocessor-based software systems have increased in scale and complexity, and rendered traditional, highly manual testing processes insufficient. Princeton Consultants developed the Signal Application Testing System (SATS), a robust simulation tool that improves and substantially automates rail system testing. SATS is now the preferred testing solution for hundreds of engineers, managers and designers.
SATS automates many tests and finds errors that may have been missed during manual assessment. SATS users find 80% or more of software errors during simulation.
SATS users find most errors in the office, not in the field, and they quickly locate problem areas. Testing an entire cutover of project at once is straightforward, saving valuable time.
With SATS, test managers instill defined processes, and better manage a growing software portfolio.
Through display of aspect progression, demonstrated train movement, and logic equation structure, SATS enables new or inexperienced signal engineers to quickly understand a signal system. Typically, new hires are performing simulation testing within two weeks of being hired.
Princeton Consultants’ SATS team responds promptly to user questions about the software—and to broader issues about PTC communications and signaling.
