The Motorola 9505 is a satellite phone designed to operate with the Iridium satellite network, offering reliable global communications even in the most remote areas. It is a rugged device, built for extreme environments, with a casing resistant to dust, shocks, and water splashes.
INSIGHTS
From a technical standpoint, the 9505 operates in the L-band (1616–1626.5 MHz) and uses a retractable antenna to ensure a stable signal. It supports voice services, SMS messaging, and data transmission at speeds up to 2.4 kbps.
The device features a monochrome display with backlighting, a durable physical keyboard, and a simplified user interface. The Motorola 9505 also includes an RS-232 port for connection to computers and external devices, allowing the use of limited data services.
The Iridium network is a global satellite telecommunications system designed to provide voice, messaging, and data services anywhere on the planet, including oceans, poles, and remote areas without terrestrial infrastructure. The constellation consists of 66 operational satellites in low Earth orbit (LEO), positioned at an altitude of about 780 km, with 6 orbital planes, ensuring continuous global coverage. Each satellite is equipped with links for direct communication with up to 4 other satellites, creating a mesh network that reduces reliance on ground stations and ensures reliability even in extreme conditions.
