STK/SOLIS

STK/SOLIS

STK/SOLIS provides a complete spacecraft simulation environment in STK, including full rotational dynamics; attitude determination and control; sensor and actuator models; and power and payload modeling.

STK/SOLIS is developed by Advanced Solutions, Inc. (ASI), an AGI business partner. ASI is an aerospace engineering company specializing in Guidance, Navigation, and Control (GN&C) systems, flight software (FSW), spacecraft assembly/integration/test (AI&T), spacecraft mission operations, spacecraft command/telemetry systems, aerospace ground data systems and dynamic space simulation.

Satellite Simulation in STK

  • Highlights

  • STK/SOLIS features an easy-to-use graphical interface for configuring spacecraft components, including the sensor, actuator, propulsion, power, communications and payload models. Spacecraft design engineers can rapidly evaluate system trade-offs and ensure that spacecraft capabilities and constraints are considered early and are being met. Once the optimal configuration is achieved, spacecraft templates can be created and saved. If mission requirements change, the templates can be quickly loaded and reconfigured to assess the impact of the changes to the spacecraft’s design.

    After an accelerated design and analysis cycle using STK/SOLIS, the resulting flight software configuration can be targeted for actual flight avionics at the touch of a button. This capability is enabled by the STK/SOLIS architecture, which embeds a desktop version of ASI's on-board flight software. This modular flight software architecture provides rapid spacecraft development, assembly, test and integration, as well as autonomous on-board operations and enhances integration and test with its high-fidelity “test like you fly” capabilities.

          See the ADF Administrators Guide for specific information about configuring an ADF Server.

          Follow instructions below to request a 90 day evaluation license and the ADF Server Installation download link.

          AGI Data Federate requires the use of a FlexNET License Server to host your license.

          Obtain the Host ID and the Hostname or IP Address:

          • Start All Programs/Accessories/Command Prompt. Right-click to 'Run as administrator'.
          • At the prompt, enter ipconfig /all
          • Under Ethernet adapter Local Area Connection, note:
            • Physical Address (Host id)
            • IPv4 Address (IP Address)
          • Send this to AGI Support (moc.iga@troppus), with the subject line "Request for ADF Licenses."

          You will receive an e-mail containing

          1. ADF Server Installation download link
          2. Detailed instructions for installing the License Server.
          3. Users are provided two *.lic files; a server license file installed on the FlexNET License Server and a client license, installed during the AGI Data Federate Server installation.
