Connecting the Uncharted: Space Norway’s Arctic Satellite Mission Takes Off

Space Norway’s Arctic Satellite Broadband Mission (ASBM) was successfully launched on Sunday August 11 (10:02 p.m. EDT). The satellites carrying several payloads will provide continuous broadband coverage to aircraft, ships, research vessels, fishing vessels, cruise ships, expeditions and troops operating in the Arctic by using a Highly Elliptical Orbit (HEO).

The satellites will run in a TAP (Three Apogee Period) orbit with the highest orbital altitude (apogee) of 43500 km and the lowest orbital altitude of 8100 km (perigee). The satellites will run in the same orbital plane with a 63-degree inclination and 8 hours separation. Each orbit takes 16 hours, and by employing two satellites, we provide full coverage throughout the Arctic north of 65 ° N (see animation). In addition, the satellites are active for about 10 hours in each orbit. This gives the satellites up to 2 hours of overlap where both satellites are operational while covering the entire area north of 65 degrees.

A lot more technical details are available here.

ASBM employs two satellites designed to operate in a highly elliptical orbit to reach the Arctic coverage area. The satellites include multiple payloads including military payloads for the U.S. and Norwegian Armed Forces, as well as a commercial payload for Viasat, and a radiation monitor for the European Commission. This marks the first time an operational DoD payload (EPS-R) will be hosted on an international space vehicle.

The European Commission is a customer for data acquisition of the Norwegian Radiation Monitor (NORM) payloads that will collect space radiation data along its orbit path, at altitudes ranging between 8,000 km and 43,000 km, benefiting to future development of several components of the EU Space Programme, like Galileo, EGNOS, Copernicus, SST, and IRIS². As these components of the EU Space programme rely on space systems that are sensitive to space radiation, regular monitoring of radiation levels is crucial to ensure the reliability and longevity of satellites in space and analyse potential disruptions of services.

Space radiation data is also useful to the scientific community. By analysing the radiation data collected by the instrument, scientists and researchers can contribute to an increase of the knowledge of space weather and of its effects on Earth's environment. 

As global interest in Arctic resources and climate research grows, initiatives like ASBM will play a critical role in supporting sustainable exploration and securing reliable communication channels in this vital region.

IEEE 802.11bn Ultra High Reliability (UHR), a.k.a. Wi-Fi 8

Back in 2020 we looked at the introductory post of Wi-Fi 7 which was followed up by a more detailed post in Feb 2022. We are now following on with an introductory post on the next generation Wi-Fi.  A new paper on arXiv explores the journey towards IEEE 802.11bn Ultra High Reliability (UHR), the amendment that will form the basis of Wi-Fi 8. Quoting selected items from the paper  below: After providing an overview of the nearly completed Wi-Fi 7 standard, we present new use cases calling for further Wi-Fi evolution. We also outline current standardization, certification, and spectrum allocation activities, sharing updates from the newly formed UHR Study Group. We then introduce the disruptive new features envisioned for Wi-Fi 8 and discuss the associated research challenges. Among those, we focus on access point coordination and demonstrate that it could build upon 802.11be multi-link operation to make Ultra High Reliability a reality in Wi-Fi 8. The IEEE 802.11bn UHR: Whose ...

Laser Inter-Satellite Links (LISLs) in a Starlink Constellation

When we first talked about Starlink back in 2019 , we saw in the video that the concept involved laser communication to communicate between the satellites. While the initially launched satellites did not have the laser communication mechanism built in, it looks like they are being added to the newer ones.  A report from Fast Company in late 2021 said: One of the next big upgrades in telecom will involve satellites firing lasers at each other—to beam data, not blow stuff up. The upside of replacing traditional radio-frequency communication with lasers, that encode data as pulses of light, can be much like that of deploying fiber-optic cable for terrestrial broadband: much faster speeds and much lower latency. “Laser links in orbit can reduce long-distance latency by as much as 50%, due to higher speed of light in vacuum & shorter path than undersea fiber,” SpaceX founder Elon Musk tweeted in July about the upgrade now beginning for that firm’s Starlink satellite constellation. ...

Tutorial Session on Current Trends and Key Challenges of Satellite communications

The 2024 Global Forum on Connecting the World from the Skies , held on November 25-26, brought together policymakers, industry leaders, and technical experts to discuss the evolving landscape of Non-Terrestrial Networks (NTNs). Hosted by the International Telecommunication Union (ITU) and Saudi Arabia’s Communications, Space & Technology Commission (CST), the event highlighted NTNs' critical role in shaping the future of global connectivity. The conference featured a rich lineup of keynote speeches, panel discussions, tutorial sessions, and an award ceremony. One standout session on Day 1 was the tutorial "Satellite Communications: Current Trends and Key Challenges," delivered by Professor Riccardo De Gaudenzi of the University of Parma. This session explored the vital role satellite networks play in global communication, from video broadcasting to bridging connectivity gaps in underserved regions. Traditionally focused on broadcasting and professional applications, s...
