OW70L-Dac - OneWeb LEO User Terminal
Chapter 2. Introduction
2.1 Introduction to OW70L-Dac
The OW70L-Dac is a dual parabolic terminal with a 73 cm reflector size based on a 12.3 dB/K G/T which
can beoperated in the OneWeb low earth orbit (LEO) satellite constellation. The OneWeb communications
networkcomprises terrestrial gateways positioned around the globe communicating with OneWeb user
terminals. Aradio link to the satellites is established using the User Terminal (UT) operating in the Ku-band,
with uplink frequencies between 14.0 and 14.5 GHz, and downlink between 10.7 and 12.7 GHz. The
antenna provides Internet access via the OneWeb satellites and OneWeb gateways.
2.2 OW70L-Dac Features
• LEO satellite scan and tracking algorithm.
• 3-axis stabilization platform with motion drift compensation solutions.
• Fully sealed to protect against outdoor environment.
• Dual-dome operation for blockage mitigation.
• Single IP allocation to common user device behind CNX when UTs are paired for blockage mitigation to
enable seamless IP-switching across UTs.
• Simple and suitable industrial design for professional installation.
• Wideband GNSS antenna improves location precision.
• Provides secure connections over GigE between router and BBU or Cell-site router.
• Remote monitoring, diagnostics and trouble-shooting to resolve issues on site, which is made available
to the end user via a local management interface.
• Ability to store multiple software versions to fallback to a known good or factory version in case of errorsin
the current working version of software.
