Title:
遠隔測定、トラッキング、および遠隔制御リンクを備えた衛星
Document Type and Number:
Japanese Patent JP3838976
Kind Code:
B2
Abstract:
The invention relates to a telemetry, control, and ranging link of a satellite; it proposes using spread spectrum transmission for the up link, i.e. for commanding the satellite and for the ranging up signal. It proposes using subcarrier modulation for the down link, i.e. for telemetry and for the ranging down signal. This makes it possible for the up link to withstand interference and to provide co-localization; on the down link, the use of subcarrier modulation makes it possible to continue using existing equipment and known solutions.
