Telestra Software

High Fidelity Radios & Communications

Telestra provides users with fully-featured military radios and comms. Users have complete control over a robust propagation model that accounts for distance and terrain. Build radios that send both voice and data with modeling for frequency hopping, crypto, SATCOM, and HF.

Radio, Receiver and Transmitter

The Radio component set provides all the sound and modeling features required for accurate simulation of radio communications. High level components such as radios transmitter, receivers, ADF receivers, and jammers allow the user to quickly model the required air, space and ground-based communications. All radio objects accurately model real-world equipment with features such as:

  • Correct reception of tones and voice based on tuned frequency
  • Transmission/Reception and station fade based on distance and signal strength
  • AM/FM transmission and band interference
  • Diffraction effects
  • Specific radio type modeling such as SINCGARS, HF, UHF, VHF, Satellite, and others
  • Crypto and Hopset system modeling
  • Tones or noises heard for encrypted radios (preamble, postamble, mis-match)
  • Antennae gain based on frequency
  • Standard or user definable background noise characteristics
  • Lightning and background noise effects
  • Communications jamming
  • Voice messages for simulation of ATIS, GCA/CCA, ground stations background radio chatter
  • Line-of-sight and over-the-horizon simulation
  • Squelch, AGC, tuning tones
  • World Positioning of radios (geocentric, geodetic)
  • Sidetone Generation and Control
  • Press-to-Talk, Hot/Cold Mic, volume control
  • Communication control panel simulation
  • Proper Half-Duplex operation
  • Separate transmit and receive frequencies within the same radio component
  • Interface with a terrain, weather or effects server for enhanced propagation modeling
  • Passing of data messages between radio objects

Communication Control Panel

The communications panel component provides modeling of vehicle radio, receiver, and communications bus routing, switching, and mixing. Simulator communication panel switch states and volume settings are sent to the Telestra server directly, without any logic manipulation by the host computer. This information is tied directly, without any logic manipulation by the host computer. This information is tied directly to the communications panel component, along with the appropriate radio and intercom components. Depending on user defined local configuration, microphone audio, as well as transmission and receive signals, are mixed and routed to the appropriate headset based on the switch and volume state information.


The Intercom component set provides sound modeling features required for accurate Intercom Switching (ICS) and communication bus simulation. Intercoms provide the capability to model complex communications structures such as: communications bus, communications control panel, audio signal routing and logic, and instructor/trainer inter-communications.

In addition, ASTi intercoms communicate over networks using DIS, HLA, or VoIP protocol. This allows a growth path for adding more operators to a system, and it allows operators in remote locations to communicate on an intercom bus.

Intercoms are ideal for shipboard communication system simulations, where many party line, point-to-point communications buses, and priority bus structures exist. Typically, these systems are bus structure oriented and existing host software is configured to drive this type of structure.

Some of the main features of Intercoms include:

  • Flexible voice switching for intercom between trainees and instructors
  • Point-to-point and party line/communication bus structures
  • Networked intercom communications
  • Voice warning and warning tone simulation
  • Bus and warning tone priority capabilities
  • Communication control panel simulation
  • Selectable full or half duplex operation
  • Sidetone generation and control
  • Press-to-Talk, vox, hot/cold mic, and volume control
  • Priority bus assignment and control
