OneWeb@PanLab

Overview

The video highlights real-world measurements from a OneWeb user terminal (UT) located in the Midwestern USA. It showcases three essential metrics: the UT’s antenna signal-to-interference-and-noise-ratio (SINR), the network latency from the UT to its associated Point of Presence (PoP) in Ashburn, and the details about connected OneWeb satellites available from the UT’s AIM tracking logs.

The video was generated with custom plots using the historical Two-Line-Element (TLE) data for OneWeb satellites, Python’s Skyfield and Cartopy libraries.

Abstract

OneWeb, the second largest low-Earth-orbit (LEO) satellite constellation, predominantly serves enterprise and government markets, presenting challenges for researchers trying to assess its network performance in practical scenarios. Consequently, the research community lacks a comprehensive understanding of the OneWeb system beyond the constellation parameters detailed in its regulatory filings and constrained simulation-based analysis. In this paper, we conduct a comprehensive network measurement study of the OneWeb satellite network, using both “inside-out” measurements for controlled user terminals (UTs) and “outside-in” measurements targeting publicly accessible UTs on the Internet. We present real-world measurements of the antenna signal-to-interference-and-noise-ratio (SINR), network latency, and throughput performance of different transport layer protocols and congestion control algorithms. Additionally, we utilize UT antenna tracking logs of connected satellites for cross-layer analysis. Our findings indicate that, while OneWeb generally fulfills its throughput service-level agreement (SLA) for enterprise and government customers, its latency performance is profoundly impacted by its constellation design. While latency remains relatively stable with minimal fluctuations during most inter-beam and inter-satellite handovers, notable latency variations occur during satellite network portal (SNP) handover events in certain geographical areas. This issue is partly due to the absence of inter-satellite links (ISLs), which presents a significant obstacle to OneWeb’s pursuit of seamless global coverage and robust network resilience.

Satellite Network Portal (SNP)
SNPs are analogous to ground stations or teleports in other satellite constellations.
The list of SNPs is compiled from the Satellite Constellation Flight Dataset by Eutelsat OneWeb on AWS Marketplace, as well as various sources from regulatory bodies across different countries.
A green marker means the GPS location is either confirmed from multiple sources or is inferred with high confidence. A purple marker means an SNP is claimed to be built in this region, but the exact location is not yet confirmed.

Point of Presence (PoP)
The locations of OneWeb PoPs are obtained from PeeringDB ASN800 Interconnection Facilities. https://www.peeringdb.com/asn/800. A purple marker means a PoP is claimed to have been built in this region, but it has not been confirmed yet or is not listed on PeeringDB.
