About
The Thrust Module (TM) is designed for spacecraft (S/C) station keeping. It was first released in 2001 and boasts a guaranteed service life of 4500 hours and 3000 cycles. The module consists of two main units: an M-70 Stationary Plasma Thruster and a Xenon Flow Controller Unit (XFC Unit). It utilizes xenon as its propellant. The product has undergone flight qualification and has a rich flight heritage, having been deployed on numerous spacecraft including those from the Cosmos series, Luch series (launched on 16.12.94, 11.10.95), Kupon S/C (launched on 16.12.94), Yamal series (launched on 06.09.99, 24.12.03), KazSat-1 (launched on 18.06.06), KazSat-2 (launched on 16.07.11), Express-MD1 (launched on 11.02.09), Express-MD2 (launched on 06.08.12), and EgiptSat-F (launched 22.02.19). The manufacturer offers the possibility to adapt the product to customer requirements. The estimated production/delivery time is 12 months, not including the time needed to procure materials (4 months) and procured parts and components (6 months).
