10 TT&C and Telecommunication Technology …
On December 2, 2013, the Chang’E-3 was successfully launched. the Chang’E3 lunar lander was the first X-band as the main frequency band that provided
telemetry/telecommand and telecommunication support in China up to date.
The X-band unified carrier telemetry/telecommand architecture was researched
for the lunar lander. The X-band telemetry/telecommand and telecommunication
subsystem that adapted to lunar soft-landing mission was designed. The X-band
telemetry/telecommand and telecommunication instruments were developed and
verified in flight. In addition, the analysis and subsystem design of UHF band
telecommunication model on lunar surface was conducted. Then after the Chang’E-3
was landed on lunar surface, telecommunication between the lunar lander and the
lunar rover was successfully implemented.
The deep space network on ground is the dedicated telemetry/telecommand and
telecommunication network that is especially designed for telemetry/telecommand
and data transmission of deep space probes. The large aperture parabolic antenna with
high-power transmitter, high sensitivity receiving system, signal processing center,
high precision and high stability time frequency system was established, which can
be used to support telemetry/telecommand and telecommunication of deep space
missions [5].
To date, the United States NASA, ESA, Russian Federation Space Administration (RFSA), Japanese space development group (JAXA), and India Space Research
Organization (ISRO) had also established a deep space telemetry/telecommand
station or telemetry/telecommand network. The deep space network consisted of
deep space ground station with large aperture antenna, deep space network management center and ground communication system. In the implementation of deep space
telemetry/telecommand and telecommunication, the mission control center carried
out the resource scheduling through the deep space network management center. The
deep space ground station connected with deep space probes through the radio link,
and interacted with the mission control center through the ground communication
network.
For requirements of future deep space missions, deep space
telemetry/telecommand and telecommunication network was developed and
built up, including the Jiamusi S/X dual-bands deep space station and the Kashi
S/X/Ka triple-bands deep space station. At the same time, S/X/Ka triple-bands deep
space station would be built up in South America, which would form the global
network of deep space telemetry/telecommand and telecommunication of China
together with the other two deep space stations.
