Iran plans to test launch its latest constellation of satellites before the end of the year, an official said on Tuesday, as the country’s space program continues to advance despite international sanctions.

Iranian Space Agency head Hassan Salarieh said the first test launches of the Martyr Soleimani satellites would occur before the end of 2025, Iranian media reported.

Nearly 20 satellites will be built in total, and their subsystems are currently under production, said Salarieh. Full-scale launches of the satellite fleet are expected in March of next year, following testing and development, he added.

Background: The Martyr Soleimani is Iran’s first narrowband satellite. Narrowband satellite communications utilize a relatively narrow range of frequencies compared to broadband, and are better suited for transmitting signals over long distances using lower bandwidth. It is often used for two-way radios, emergency communications and the Internet of Things — meaning devices that connect to others through the internet.
