Non-geostationary Satellite Delay / Doppler Simulator

Laboratory Evaluation & Hardware Emulation System

Overview & Key Features

Designed for comprehensive laboratory testing, this simulator enables evaluation of satellite communication equipment prior to live deployment on non-geostationary satellites.

Pre-Deployment Testing

Used to thoroughly evaluate satellite communication equipment in the laboratory prior to using actual non-geostationary satellites.

Supported Platforms

Hosted on AMD Zynq UltraScale+ MPSoC ZCU102 (with AD9361 RF Transceiver) and RFSoC ZCU111 Evaluation Kits.

Network Parameter Ingestion

Reads network parameters including Two-line element (TLE) data, satellite schedules, and channels information from SDB files.

Orbit & Link Estimation

Precisely estimates satellite coordinates, expected path delay, and Doppler shifts across the link.

Monitor & Control Interface

Features a CLI-based Monitor and Control (M&C) system to configure and monitor simulation parameters in real time.
