New Delhi: ISRO is launching the LVM3-M6 flight on 21 December, to deploy the BlueBird 6 satellite for AST Spacemobile based in Texas, USA where the satellite was built. The launch was previously scheduled for 15 December. AST SpaceMobile is deploying the first and only space-based cellular broadband constellation that offers connectivity directly to standard smartphones without any special equipment or modifications. The idea is to provide coverage in dedadzones worldwide, and provide connectivity in underserved areas. The idea is to eventually provide full 4G/5G broadband connectivity with coverage across the entire planet. AST SpaceMobile plans to deploy between 45 and 60 satellites by the end of 2026.

The satellites use large phased arrays to compensate for the small, low-power antennas used in smartphones. The BlueBird 1-5 satellites, launched by SpaceX last year had antennas stretching across 64 square metres, while the next-generation BlueBirds that are three times larger, have antennas as large as 222 square metres, offering ten times the capacity. ISRO is launching the first of these satellites, with AST SpaceMobile aiming for five launches by March 2026. AST SpaceMobile has purchased rides to space on board the New Glenn rocket by Blue Origin, as well as the SpaceX Falcon 9 rocket. Founder, CEO and Chairman of AST SpaceMobile, Abel Avellan says, “Our next-generation satellites will soon enable ubiquitous cellular broadband coverage direct to everyday smartphones from space.”

Potential Applications

The space-based cellular broadband network has a wide variety of potential applications, for both civilian and government users. Healthcare, education and banking services can be extended to remote and isolated communities. Travelers in remote, off-grid locations can check weather and navigate safely, while sharing their locations. The infrastructure can also support agricultural IOT solutions. For passengers on aeroplanes and ships the technology can provide uninterrupted connectivity throughout the travel period, without the use of expensive WiFi. In emergency situations, the connectivity can be sustained even when terrestrial networks are impacted.
