TelSim™ Telemetry Simulator

Real-time Dynamic Telemetry Simulation Appliance

The TelSim™ all-in-one Telemetry simulation environment is designed to solve your mission simulation, telemetry ground systems testing, and training needs in a turnkey package. It can be configured for anything from simple pattern generation to interactive modeling or real-time automated control sequences. TelSim™ provides dynamic real-time telemetry simulation using automated reactive control via simple user interaction.

Operations and test organizations can enhance personnel and systems readiness without impacting availability of operational assets, accommodating a full range of realistic nominal and non- nominal mission scenarios. The TelSim™ provides real-time generation of complex serial data streamer, including IRG 106 compliant telemetry. It’s capable of fully independent operation that can be plugged-in to any telemetry ground station as a headless server, or with a fully interactive multi-user graphical user interface.

Major Features

  • Fully integrated simulation environment that can model the continuous or discrete time behavior of any external system.
  • Dynamic data is commutated into a telemetry transmission stream in real-time
  • Mission scenarios are easy to define and organize.
  • Simple user-friendly operation makes TelSim™ ideal for supporting all phases of testing and training.

Typical Applications

  • Ground systems test/ verification
  • Interactive operations crew training (nominal & non-nominal dynamics)
  • End-to-end mission simulations and dress rehearsals

The TelSim™ modeling engine allows a systems engineer to quickly create interactive models using a point and click GUI or high level scripting language. A programming library is also available that supports the integration of 3rd party models.

TelSim™ enables simulations to be scalable in fidelity so they can operate stand alone, or integrated with other models to create large-scale mission simulations. TelSim™ also supports telemetry acquisition, processing, and recording for mission playback and replay of post decom data with simulation models.

Specifications

Architecture

  • Real-time IRIG 106 telemetry simulation appliance capable of fully independent operation that can be plugged into any telemetry ground station.
  • Supports simultaneous telemetry acquisition, processing and recording for missions playback and replay of post decom data with simulation models.
  • Modular software architecture decouples telemetry– processing details from simulation environment.
  • Built on top of generic real-time command and control middle ware that includes service for data processing, visualization, archived, data reduction and analysis, and network centric operation.
  • Configuration and telemetry description managed using validation XML. Can exchange format data with any database scheme.

Simulation

  • Real-time and user configurable variable time engine.
