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. The Arct
The ATIS Workshop on Synchronization and Timing Systems (WSTS) was held in May 2024.Valued for its insight into synchronization and timing fundamentals, the WSTS Tutorial has been a highly anticipated part of the conference since its inception. The videos and presentations from the tutorial sessions are all available here . For anyone unaware, timing & synchronization are critical in communication systems because they ensure data is sent and received correctly between devices. In networks like the internet, computers need to be in sync to avoid data getting scrambled or lost. For example, in wireless communications like Wi-Fi or mobile networks, both the sender and receiver must be perfectly timed to work on the same frequency, ensuring messages don’t overlap or cause interference. Without this coordination, you would have slower or interrupted connections. Timing is also important for managing how devices share network resources. In systems like time-division multiplexing (TDM), e
