New products for LEO/MEO and MIMO simulation

(4 January 2021) PPM Systems has expanded its range of channel simulators to include the IZT C5040 for Low Earth Orbit (LEO) and Medium Earth Orbit (MEO) satellite constellations, as well as the C7000 RF Multiple Input Multiple Output (MIMO) Emulator for Mobile ad-hoc networks (MANET) and 5G testing.

The IZT C5040 is ideal for simulation of LEO/MEO satellite constellations involving complex handovers with variable path lengths and losses to the ground stations. The system has been designed to be to be driven using real constellation data or an external orbit simulator.

The IZT C7000 is a high-performance simulator system for testing 5G and MIMO radio system solutions in the frequency range of 30 MHz to 6 GHz, with 80 MHz instantaneous bandwidth.

Paul Cotterill, Business Development Manager, said: “These new products from IZT focus on emerging markets and address the requirements for hardware testing in a controlled environment by simulating new complex RF environments.”

These RF solutions for LEO/MEO satellite constellations and MANET radio links will become increasingly important in the next few years. The emerging constellations will expand markets for small satellites and global internet service providers. The MANET radio links will be used by army and law enforcement units transitioning to more agile digital mesh radio networks, for enhanced mission data support.
