ASBM 1 & 2

Pioneering Arctic communication

Space Norway's ASBM satellites are part of their Arctic Satellite Broadband Mission, designed to provide reliable, high-speed connectivity to the Arctic region.

The ASBM 1 and ASBM 2 satellites work in tandem to provide continuous broadband coverage north of the 65° N latitude. To maintain uninterrupted coverage, these satellites follow a highly elliptical orbit. The highest orbital altitude, or apogee, is 43,500 km when the satellites are over the northern regions, while the lowest orbital altitude, or perigee, is 8,100 km when they are over the southern hemisphere.

The ASBM satellites operate in a TAP (Three Apogee Period) orbit, featuring an apogee of 43,500 km and a perigee of 8,100 km. These satellites share the same orbital plane with a 63-degree inclination and are separated by 8 hours.

Each complete orbit takes 16 hours, and with two satellites, Space Norway ensures comprehensive coverage throughout the Arctic north of 65° N. The satellites are active for approximately 10 hours in each orbit, including up to 2 hours of overlap where both satellites are operational, ensuring thorough coverage of the region.

Facts about the satellites

The satellites each weigh around two tons, are approximately 3x3x4 meters in size, and have a wingspan with unfolded solar panels of about 27 meters.

The two satellites were stacked on top of each other in the rocket.

Payloads

Onboard the ASBM satellites are payloads from the Norwegian Armed Forces, the U.S. Space Force, and Viasat, a commercial satellite operator. Notably, this mission marks the first instance of a U.S. military payload being hosted on a foreign satellite.

Additionally, one of the satellites carries a Norwegian-developed payload designed to measure radiation levels in space, providing valuable data to the European Commission for their work on the new Galileo communication satellites.

 

Launch

The ASBM 1 and 2 satellites were launched in August 2024 by a SpaceX Falcon 9 rocket. From their high elliptical orbit (HEO), these satellites provide continuous broadband coverage north of the 65° N latitude, offering unique and reliable broadband access in regions where conventional satellite coverage from both geostationary and low orbit satellites is not feasible.
