Poland is set to launch domestically-developed satellites this September as part of the groundbreaking Piast project, spearheaded by the Military University of Technology (WAT) in Warsaw. The mission's primary focus is testing laser-based communication between nanosatellites and Earth stations.
The innovative technology uses light beams for data transmission, offering superior security compared to traditional radio communications. "The war in Ukraine has shown that using radio emitters, such as radars, makes them easy targets. Laser communication offers a solution—it cannot be jammed, intercepted or detected," explained Col. Jacek Wojtanowski, an optoelectronics expert at WAT.
During the mission, the satellites will demonstrate high-speed laser-based data exchange capabilities. "The satellites will connect with each other using lasers at very high data transfer speeds," said Wojtanowski. "One satellite gathers information and then 'drops' it to Earth. With lasers, we can transmit any type of data—images, sound, or files in any format."
While the technology shows promise for both military and civilian applications, it does have certain limitations. The system requires an unobstructed line of sight between transmitter and receiver to function properly.
In parallel developments, WAT has successfully tested a laser-based weapon system capable of neutralizing enemy drones. This technology offers several advantages over conventional weapons, including silent operation and cost-effectiveness, with each shot costing only a few dollars.
The upcoming satellite launch represents a major step forward in Poland's space capabilities and could revolutionize secure communications for defense and commercial applications. The success of this mission could position Poland as a leader in laser-based space technology.
