Globalstar-2 FM15 was the eighth of a planned 52 (48 operational and 4 on-orbit spares) satellites in the Space Systems Loral "Big LEO" global mobile communications network offering global real time voice, data and fax, was launched on a Delta II rocket from Cape Canaveral. The satellite was 3-axis stabilized and employed magnetometers on a deployable boom, sun sensors, GPS as attitude sensors, and carried two deployable solar arrays delivering 1100W.

Globalstar added a spare spacecraft to its commercial data relay network early Sunday with a launch from Cape Canaveral on a SpaceX Falcon 9 rocket, but the satellite operator remained silent about the mission on the eve of liftoff. SpaceX has announced the mission — first reported by Spaceflight Now — and hosted a live webcast of the launch, at 12:27 a.m. EDT Sunday from pad 40 at Cape Canaveral Space Force Station.
SpaceX did not mention any payloads that could be riding to orbit with the Globalstar FM15 satellite. The relatively light weight of the Globalstar satellite would typically leave enough propellant reserve on the Falcon 9’s booster to return to landing, but Sunday’s mission will feature a landing on SpaceX’s “Just Read the Instructions” offshore recovery platform. Booster landed on target at about 8 1/2 minutes after launch.
But Globalstar, the only acknowledged customer on the mission, has made no public disclosures about the launch of its spare satellite other than a statement in a quarterly financial report last month that said it planned to launch the backup spacecraft in the “near future.” At the time, the company did not identify the launcher for the spare satellite. SpaceX has confirmed it plans to launch the spacecraft, known as Globalstar FM15, from Cape Canaveral after midnight Sunday. Airspace warning notices indicate the Falcon 9 will head downrange to the northeast from Florida’s Space Coast, with SpaceX’s drone ship “Just Read the Instructions” in position about 400 miles downrange from Cape Canaveral.
The reusable booster flying on the Globalstar mission is tail number B1061, making its ninth trip to space. The launch early Sunday will cap a busy couple of days for SpaceX, as the company goes for its third Falcon 9 mission in roughly 36 hours. Two Falcon 9s launched from the Kennedy Space Center on Friday and then Saturday from Vandenberg Space Force Base in California, hauling 53 Starlink internet satellites and a German radar reconnaissance spacecraft into orbit. Sunday’s mission will be SpaceX’s 26th launch of the year, matching the total number of Falcon 9 missions flown in 2020. SpaceX accomplished 31 missions last year, the company’s current record for a calendar year. Officials are aiming for more than 50 Falcon 9 and Falcon Heavy flights this year.
The Globalstar-2 FM15 launch will be the first for a Globalstar satellite since 2013, and adds capacity for the company’s commercial network providing data connectivity for satellite phones, asset tracking, and internet-of-things applications. Globalstar operates a fleet of dozens of communications satellites in low Earth orbit.
The company launched 60 first-generation satellites, built by Space Systems/Loral, on Delta 2 and Soyuz rockets from 1998 through 2007. Globalstar added 24 second-generation satellites, manufactured by Thales Alenia Space, on four Soyuz rocket missions from 2010 through 2013. “Our constellation of Low Earth Orbit (LEO) satellites includes second-generation satellites and certain first-generation satellites,” Globalstar said in a quarterly report filed with the Securities and Exchange Commission last month. “We also have one on-ground spare second-generation satellite that we plan to launch in the near future.”
The Thales-built Globalstar satellite weighs about 1,543 pounds. The Globalstar fleet orbits about 878 miles above Earth at an inclination of 52 degrees to the equator, an orbit reachable with a launch to the northeast from Cape Canaveral. The Globalstar satellites provide data connectivity for customers between 70 degrees north and south latitude, and the company’s second-generation spacecraft are designed for operational lifetimes of 15 years. The Thales-built Globalstar satellites are trapezoidal in shape and feature 16 transponders in C-band and S-band and 16 receivers in L-band and C-band.
Globalstar is a competitor in the satellite phone and data relay market with companies like Iridium, Inmarsat, and Orbcomm. Globalstar announced in February it is purchasing 17 new satellites from an industry team led by MDA and Rocket Lab to extend the life of its constellation. The company expects all of the 17 new satellites will be launched by the end of 2025. A launch service provider for the new satellites hasn’t been announced. The $327 million contract for the 17 new satellites, along with the launch this month of Globalstar’s spare second-generation spacecraft, is being primarily funded by an unnamed “potential customer” for Globalstar’s services.
