Rocsat 2
|
ROCSAT 2 (Republic of China Satellite) is the second high-resolution
Earth observation satellite for the Taiwanese National Space Programme
Office (NSPO).
Rocsat is a regional remote sensing satellite for the collection
of data for natural disaster evaluation, agricultural applications,
urban planning strategy, environmental monitoring, and ocean surveillance.
The Rocsat 2 Attitude and Orbital Control System is based on 4
x 1 N
monopropellant thrusters supplied from a 104 litre monopropellant
N2H4 surface tension tank.
Propulsion Module
The Rocsat 2 propulsion system is typical of the many
self contained 'plug-in' propulsion modules supplied by Lampoldshausen.
The module, comprises the complete propulsion system together with
all of the associated sensors, heaters, thermistors, pressure transducers
and harness elements.
The 'plug-in' propulsion module provides just two interfaces:
 A
structural interface to the satellite.
A single
electrical interface via connectors.
The following provides a pictorial insight into the Rocsat activities
