+==== Introducing the Orbiter Power System ====
-The power supply system, or PSS, is the heart of the satellite. The power supply system of real satellites charges the batteries from [[sun_battery|solar batteries]], converts the voltage of the batteries into a stabilized board voltage to supply to various devices. In some cases, the PSS is able to turn the power of individual consumers on or off either on-command or automatically.
+Virtual power draw: 60 mA
-In the construction set, the power supply system includes a rechargeable battery. The presence of solar panels and the logic of rechargeable batteries are "virtually" considered. The "virtuality" of solar batteries is related to the fact that charging batteries from real solar panels is difficult in a room; the effective charge would require an excessively large solar panel surface area. Therefore, the PSS is arranged as follows. The first part of the PSS (real) provides energy to all of the consumers. It is charged from the 220V network and contains enough energy for a "flight" of up to 4 hours. The second part of the PSS (virtual) simulates the operation of the satellite PSS. It has a limited supply of virtual energy. The virtual part is visible at the request of PSS telemetry. This energy is replenished when the solar panel imitator is placed on the [[sim_sun|Sun simulator]]. When the virtual energy is exhausted, the task executed by the "spacecraft" is abruptly terminated - as happens in real life.

-The real power supply system includes a voltage converter, a charger, and a rechargeable battery. The charger included in the construction set charges the battery. The PSS is connected to the on-board information network/power network with [[wiring|standard loops]].
+The Orbiter Power System (OPS) is the heart of the satellite. In real-world satellites the power supply system charges rechargeable batteries from solar cells and converts battery voltage into stabilized orbiter voltage to power various devices. In some cases power to individual consumers can be turned off and on by OPS upon receiving a command or automatically.
-During normal operations, the "satellite" is completely autonomous, and is powered only by on-board batteries, gradually expending its virtual and real energy reserves while carrying out the flight program put on-board.
+The power supply system in the construction set contains a battery while solar cells and battery recharge/discharge logic are accounted for “virtually”. This “virtualization” of solar panels owes itself to the difficulty of recharging batteries with solar cells indoor as solar cell surface area would have to very large for batteries to recharge adequately. For that reason the OPS has been designed as follows. The first (real) part of OPS does the actual job of distributing power to all consumers, recharging batteries from 220 VAC mains and holding enough energies for a “flight” lasting up to 4 hours. The other (virtual) part simulates orbiter power system operation and stores a limited amount of virtual energy. This is what the user sees when requesting telemetry from the OPS. This energy is replenished when the solar cell simulator is pointed toward the Sun simulator. Once virtual energy is fully exhausted the “orbiter” will fail its mission – as would be the case in the real world.
-As part of the "ground" service before the flight, the on-board batteries, of course, need to be recharged. For this purpose, the charger is connected to the 220V network. In this case, the LED indicator on the PSS lights up in green. In the case of battery discharge to the load (to the satellite network), the LED lights up red. When the network is switched on and the load is simultaneously connected, the LED lights up in yellow.
+The real power supply system includes a power adapter, a battery charger and a rechargeable battery. The battery can be charged using a charger packaged with the construction set. The power supply system hooks up to the onboard data/power network by means of standard ribbon cables.
+The “satellite” is fully autonomous during normal operation, only supplied by orbiter batteries as it gradually expends its store of virtual and real energy by executing its flight program.
+Naturally, orbiter batteries will have to be charged as a part of pre-flight “ground maintenance”. To that end the charger connects to 220VAC mains. In this case the signal LED on the OPS will light up green.
+<note warning>
+**//It is not recommended to leave the power system connected to the charger without load for extended time (longer than 4 hours) when working with the satellite. Such a connection may shorten the battery life. Other power-up combinations are allowed.//**

-**Important notes** \\
-When working with the satellite, it is not recommended to leave the PSS connected to the charger for a long time (more than 4 hours) when there is no load (green LED color). This connection can shorten the battery life. Other combinations of connections are allowed.
