Our next milestone is a flight demonstration in low earth orbit, which will prove the technology of PLT-enabled precision formation flying and stationkeeping
with small satellites," according to Dr.
The 145m long vessel has a 400 tonne crane, DP3 stationkeeping
, and notation to work in Arctic waters.

SS/L's satellites are designed to achieve long useful orbital life through use of bipropellant propulsion and momentum-bias systems for excellent stationkeeping
and orbital stability.
There are generally only three types of measurable partial losses that affect a satellite after launch: transponder failures(s); insufficient stationkeeping
fuel, which results in a reduction in mission life; and insufficient power, which results in either an immediate or future quantifiable reduction in the satellite's transponder or mission life.
The satellites are designed to achieve long useful orbital life, precise stationkeeping
, excellent fuel economy and orbital stability by using advanced propulsion and stabilization systems.
Contract notice: Framework agreement related to basic design to be carried out with regard to the floating sub-structures, the stationkeeping
systems, the inter-array cables and construction and installation~s methods for the following contracting entities acting as a purchasing group Parc Eolien Offshore de Provence Grand Large SAS and Nenuphar SA.
The lightweight and high-strength structure-with fuel-efficient attitude and stationkeeping
subsystems, high-efficiency solar arrays and batteries, and advanced command and control subsystems-offers high power, stable pointing, extensive flexibility, and a long mission life.
will perform orbit raising and stationkeeping
This contract, dubbed "SSAS", entails stationkeeping
and support services for the Syracuse 3A, Syracuse 3B and Athena-Fidus satellites, along with the "French" part of the Sicral 2 satellite.
a wholly-owned subsidiary of American Pacific Corporation ("AMPAC-ISP"), is pleased to announce that Space Systems/Loral (SS/L) will use AMPAC-ISP's 5-lbf Platinum/Rhodium thruster to provide margin for orbit insertion as well as on-orbit stationkeeping
for the Telstar 11N communications satellite.
SS/L's satellites use bipropellant propulsion and momentum-bias systems for excellent stationkeeping
and orbital stability, providing long useful orbital life.
