What is the function of PCU?
During acceleration, the PCU coverts a battery’s electric power from DC to AC and then supplies power to the motor. During deceleration, it converts electric power from AC to DC to recover the regenerated electric power.
What does EPS stand for satellite?
The primary role of the Electrical Power System (EPS) is to supply other systems in the satellite with the necessary electrical power to operate effectively. The source of the power is the energy collected from the solar panels which are exposed to direct solar radiation or to indirect radiation from albedo.
How the satellite and power system is related?
Description. Satellites harness power from solar panels to power spacecrafts. This high voltage supply needs to be stored and converted for all the onboard electronics. Our large portfolio of space-qualified devices and reference designs help you maximize your system performance.
What kind of electric power supply is used in satellite?
Today most satellites rely on advanced solar cells with an efficiency around 30% and on Li-ion batteries.
What is PCU in network?
Part of a GPRS BSS product, the PCU provides an interface between the SGSN and the radio network using frame relay technology.
What is the purpose of PCU in GPRS and where is it located?
The Packet Control Unit is a device found within a GPRS network which is logically associated with a BSC (Base Station Controller). The PCU is responsible for the radio related aspects of GPRS when connected to a GSM network and lies between the BTS (Base Transceiver Station) and the SGSN (Serving GPRS Support Node).
What is EPS in CubeSat?
Electrical Power Supply (EPS) The Electrical Power Supply, or EPS of the CubeSat is composed by three modules which are the PCC (Power Control Circuit), the PV (photovoltaic panel) and the BAT (Battery). The role of the EPS is to generate, store and distribute the electricity produced by the solar panels.
What is EPS inverter?
EPS is the fire emergency power supply, and UPS is the uninterruptible power supply.
How much power does a satellite use?
between 1 and 1.5 kilowatts
Today’s satellites are frugal with power, which is usually supplied by arrays of solar cells. A typical communications satellite needs between 1 and 1.5 kilowatts of electricity, and the space shuttle manages on 12.5 kilowatts.
What are satellites used for?
Communications satellites help us communicate with people all over the world. Weather satellites help us observe the Earth from space to help predict weather patterns. Radio and television satellites beam our favorite songs, movies, and television shows to Earth for us to enjoy.
How do satellites get their power?
The main source of power is sunlight, which is harnessed by the satellite’s solar panels. A satellite also has batteries on board to provide power when the Sun is blocked by Earth. The batteries are recharged by the excess current generated by the solar panels when there is sunlight.
What is difference between GSM and GPRS?
The GSM is a circuit-switched type of network. The GPRS is a packet-switched type of network. The GSM technology provides a data rate of about 9.6 kbps (kilobytes per second) for all of its users. The GPRS technology provides a data rate of about 14.4 kbps to 115.2 (kilobytes per second) for all of its users.
