Multi-Hop, Time-Varying SatCom Link Analysis

Use Satellite Communications Toolbox™ to create a satellite scenario that models a multi-hop link with two satellites and two ground stations.

With Satellite Communications Toolbox, you can:

• Specify the satellite orbits using standard orbital elements such as semimajor axis, eccentricity, and inclination.
• Model transmitters, receivers, and steerable gimbals for the satellites and ground stations.
• Populate the transmitters and receivers with gaussian antennas.
• Specify the pointing of each transmit and receive antenna to maximize the received power at each node in the link.
• Use a free space path loss model to calculate the received Eb/No at each node in the link.
• Propagate the orbits for a day and calculate when the multi-hop link closes.
• Show the link closures graphically with a three-dimensional view of the earth.
• Show them textually, in a table that lists the beginning and end times of each link closure throughout the day.
• Use the Satellite Scenario Viewer to play the scenario animation at any desired speed, to rewind the animation, to pause it, and to jump to any point in the timeline.
