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.

Highlights from XGMF's Conference to Advance Millimetre Wave Technology

On April 1, 2024, two of Japan's leading connectivity organizations—the 5G Mobile Promotion Forum (5GMF) and the Beyond 5G Promotion Consortium (B5GPC)—joined forces to create the XG Mobile Promotion Forum ( XGMF ). This merger symbolizes a pivotal step in accelerating the adoption of next-generation wireless technologies. In May 2024, XGMF's Millimeter Wave Promotion Ad Hoc (Millimeter Wave AH) hosted the International Workshop on Millimeter Wave Dissemination for 5G. This event aimed to foster the adoption of millimeter wave (mmWave) technology in Japan and beyond, drawing an audience of approximately 200 attendees and broadcasting in both English and Japanese. The workshop featured opening remarks by Mr. Naohiko Ogiwara, Director of the Radio Department, Telecommunications Infrastructure Bureau, Ministry of Internal Affairs and Communications (MIC). Key speakers included: Mr. Takanori Mashiko (MIC, slides ) Mr. Sam Gielges (Qualcomm, online - no slides) Mr. Christopher Pric...

Testing, Refining, and Improving Stratospheric Connectivity: NTT Docomo’s HAPS Trials

At MWC 2025, NTT Docomo highlighted its latest initiatives under the NTT Group's "NTT C89" space-business strategy, such as mobile-connectivity services using unmanned vehicles, or high-altitude platform stations (HAPS), that fly in the stratosphere for days or months, using relays to provide mobile connectivity in mountainous and remote areas, including at sea and in the sky. A presentation on NTT C89 Aerospace Business Strategy is available here while a presentation on NTT DOCOMO's Non-Terrestrial Network (NTN) for Extreme Coverage Extension is available here . Stratospheric connectivity, enabled by High Altitude Platform Stations (HAPS), is emerging as a key solution for extending mobile coverage to remote and underserved areas. However, ensuring that these airborne platforms can provide stable, high-quality connectivity requires extensive testing and refinement. At MWC 2025, NTT Docomo showcased its progress in this domain, highlighting multiple real-world trials...

How Do Apple AirTags Work?

Apple AirTags have steadily gained popularity in the smart tag market. A recent report highlighted that 69% of smart tag buyers in late 2024 chose an Apple AirTag. This marks a significant rise from 45% in early 2022. In contrast, Tile, the category pioneer now owned by Life360, has seen its market share fall to 11% from 17% during the same period. Samsung's Galaxy SmartTags now hold second place. Interestingly, the technology behind AirTags resembles concepts like Opportunity Driven Multiple Access (ODMA) or Multihop Cellular Networks (MCNs), which I have previously explored . A similar approach has also been discussed regarding Bluetooth-based Ad-Hoc networks . How Do They Work? AirTags primarily use Bluetooth Low Energy (BLE) to communicate with nearby Apple devices that are part of the Find My network. This vast network consists of millions of Apple devices, including iPhones, iPads, and Macs, which can detect AirTags and securely relay their location back to the owner. Addit...
