VDE-SAT Validation Platform - Cost effective VDE-SAT User Terminal and Ground Component Validation Platform

Objectives

The hardware and software allows characterisation of all VDES satellite uplink elements. 

Challenges

The CDMA demodulator works at Ec/N0 of -13 dB, and the VDES draft standard had to be changed.

Benefits

There is no similar equipment available from other sources. The global system software simulator works at a packet level and runs much faster than real time.

Features

Can be used to test VDES uplink transmitters and satellite receivers. System performance such as throughput, latency and success rates can be optimised for a very wide range of conditions/assumptions.

System Architecture

The system is split into software simulation of packet level performance and a separate Physical Layer module.

Hardware and SDR waveform generation is used to generate real life signals.

Plan

The milestones are KO, BDR, PDR, CDR, TRR and FR.

Current status

The project achieved TRR in December 2017.
