AlliedSignal Technical Services Cooperation was the prime contractor
for design and implementation of the Ground Segment for the Republic of China.
The ROCSAT Ground System (RGS) has two major goals: building the basic
infrastructure of the ground segment and assuring the mission's success.
It consists of the Tracking, Telemetry and Command (TT&C) stations, the
Ground Communications Network, the Mission Operations Center, the Mission
Control Center, the Science Control Center, and the Flight Dynamics Facility.
ATSC's Tasks involved include system analysis, requirements definition, software
design and implementation, and system integration and testing. Also included
in the contract is the training of Operations and Maintenance team, made
up of personnel from NSPO and domestic industries.
The development of the RGS system requires the use of open system architecture
with modular design and it must be easily modifiable to serve future missions,
i.e., ROCSAT-2 and ROCSAT-3 in order to achieve its long range goal. The
transfer of technologies through the participation of domestic industries
and the academia will enhance local industry capabilities in the areas of
large-system development as well as mission operations and maintenance.
Telemetry, Tracking and Command Station
The two Telemetry, Tracking and Command (TT&C) stations provide the RF
links between the RGS and satellites. The capabilities of TT&C are telemetry
reception, satellite tracking and command transmission. TT&C consists
of Front End Processors, RF equipment, baseband equipment and antenna drive
and control circuits.
There are two stations in the mission located at north and south of Taiwan,
respectively. In normal operation, TT&C is controlled by Mission Operations
Center (MOC) located in Hsinchu via the T1 trunks. In any emergency, the
operation personnel can reside in the stations and TT&C will perform
the same functions as the MOC. |
