L-Band
A lower frequency range used for satellite communications, known for its reliability in adverse weather and suitability for mobile applications like satellite phones and GPS.
TECHNICAL DEFINITION
L-Band designates the microwave frequency range from approximately 1 to 2 GHz, primarily used for mobile satellite services (MSS), satellite navigation (GNSS/GPS), and some fixed satellite services, characterized by its resilience to atmospheric conditions and suitability for smaller, mobile terminals.
BACKGROUND
Firefly Aerospace Blue Ghost, or simply Blue Ghost, is a class of lunar landers designed and manufactured by the American company Firefly Aerospace. Firefly builds and operates Blue Ghost landers to deliver small payloads to the surface of the Moon. The first Blue Ghost mission was launched in January, 2025. It successfully landed on the Moon on March 2, 2025. The landers are named after the firefly species Phausis reticulata, known as blue ghosts.
