JSS
JSS was a large contract that included the Link-16 Network Management System (NMS), Link-16 Monitor Feedback, Link-11 HF/Terminal, Satellite, JREG, and MTN Integration. I worked on the Link-16 Monitor Feedback and Link-11 HF/Terminal. This page contains a very brief description of the project.
My tasks for the JICO Support System included:
- Link-16 Monitor Feedback
- TCP/IP interface to receive position updates.
- Prediction of platform position at a specified time interval in the future. This was accomplished using linear projection based on the velocity vector.
- Ability to switch display of platforms between future and present locations.
- Ability to determine UHF link connectivity in either present or future location.
- Link-11 HF/Terminal
- Developed a system capable of interactively building and reading-in Link-11 HF scenarios.
- Link-11 platform deployments.
- Movement paths.
- Link-11 Participating Unit (PU) radio parameters.
- Link-11 PU antenna parameters.
- Provided the ability to create and read-in environmental parameters.
- Man-made noise.
- Minimum takeoff angle.
- Required reliability.
- Required SNR.
- Multi-path settings.
- Sunspots.
- Provided the ability to interactively build and read-in Link-11 Nets.
- Link-11 PU parameters, e.g., NCS, etc.
- Net characteristics, e.g., audio signaling, etc.
- The system provided visualization of:
- High Frequency (HF) Radio Frequency (RF) connectivity.
- Link-11 network connectivity.
- Dynamic platform movements.
- Integrated the HF Radio Propagation Model.
- Dynamic computation of HF radio connectivity against 3D terrain.
- Input and operation with solar events, time of day and year, antenna characteristics.
Additional tasks:
- The Automated Correspondent Analysis System (ACAS) and Link-11 HF/Terminal both utilized the HF Propagation Prediction System. Much of the Graphical User Interface (GUI) developed for Link-11 was also integrated into ACAS. Additionally, I modified an existing worldmap overlay and added a latitude/longitude grid for use in ACAS.
