LCUT

- Low-Cost User Terminal for Satcoms

STATUS | Ongoing
STATUS DATE | 22/11/2021
ACTIVITY CODE | 7B.063

Objectives

The objective of the proposed activity is to develop a family of user terminals for Ka band MEO and LEO constellations that can be sold at a low enough price-point to enable operators to provide satellite broadband affordably to the large, transient and growing under-connected global communities. 

The terminals are designed to have a low cost, high performance, improved tracking, and dual antenna capability.

Plan

The project began in October 2021 and the key milestones are as follows:

  • System Requirements Review – Q1 2022
  • Preliminary Design Review – Q2 2022
  • Critical Design Review – Q3 2022
  • Test Readiness Review – Q2 2023
  • Formal Qualification Review – Q4 2023
  • Project Completion – Q1 2024

Current Status

The project is currently refining the system level requirements and producing the subsystem requirements. Some early elements of low-risk design are in progress.
