TdS1 (March 2003) is an innovative PNN thruster capable of delivering at now thrust with very high accuracy and controllability. It is a propellantless (no reaction mass or energy) system closed in a box.
The TdS1 technology is developed at Associazione Sviluppo Propulsione Spaziale (ASPS).
The application range of TdS1 covers the .1 microNewton – 45.2 microNewton thrust range per watt.
Its specific impulse is very high and greather than phothon rocket and solar sails of a factor in the range of 1000 - 14000.
TdS1 is at now, for low and very long thrust missions.
The thruster main features are:
