The Imaging Science Subsystem made up of a wide-angle and a narrow-angle camera is a modified version of the slow scan vidicon camera designs that were used in the earlier Mariner flights.
The Imaging Science Subsystem consists of two television-type cameras, each with eight filters in a commandable filter wheel mounted in front of the vidicons.
There are three different computer types on the Voyager spacecraft, two of each kind, sometimes used for redundancy.
They are proprietary, custom-built computers built from CMOS and TTL medium scale integrated circuits and discrete components.
Total number of words among the six computers is about 32K. Voyager 1 and Voyager 2 have identical computer systems.
The Computer Command System CCS , the central controller of the spacecraft, is two bit word, interrupt type processors with words each of non-volatile plated wire memory.
During most of the Voyager mission the two CCS computers on each spacecraft were used non-redundantly to increase the command and processing capability of the spacecraft.
The CCS is nearly identical to the system flown on the Viking spacecraft. The Flight Data System FDS is two bit word machines with modular memories and words each.
The Attitude and Articulation Control System AACS is two bit word machines with words each. Unlike the other on-board instruments, the operation of the cameras for visible light is not autonomous, but rather it is controlled by an imaging parameter table contained in one of the on-board digital computers , the Flight Data Subsystem FDS.
More recent space probes, since about , usually have completely autonomous cameras. The computer command subsystem CCS controls the cameras. The CCS contains fixed computer programs such as command decoding, fault detection, and correction routines, antenna pointing routines, and spacecraft sequencing routines.
This computer is an improved version of the one that was used in the Viking orbiter. There is only a minor software modification for one of them that has a scientific subsystem that the other lacks.
The Attitude and Articulation Control Subsystem AACS controls the spacecraft orientation its attitude. It keeps the high-gain antenna pointing towards the Earth, controls attitude changes, and points the scan platform.
The custom-built AACS systems on both craft are identical. It has been erroneously reported  on the Internet that the Voyager space probes were controlled by a version of the RCA RCA CDP "COSMAC" microprocessor , but such claims are not supported by the primary design documents.
The CDP microprocessor was used later in the Galileo space probe , which was designed and built years later. The digital control electronics of the Voyagers were not based on a microprocessor integrated circuit chip.
The uplink communications are executed via S-band microwave communications. The downlink communications are carried out by an X-band microwave transmitter on board the spacecraft, with an S-band transmitter as a back-up.
All long-range communications to and from the two Voyagers have been carried out using their 3. The high-gain antenna has a beamwidth of 0.
Because of the inverse-square law in radio communications , the digital data rates used in the downlinks from the Voyagers have been continually decreasing the farther that they get from the Earth.
For example, the data rate used from Jupiter was about , bits per second. That was halved at the distance of Saturn, and it has gone down continually since then.
Whilst the craft were between Saturn and Uranus the onboard software was upgraded to do a degree of image compression and to use a more efficient Reed-Solomon error-correcting encoding.
Then between and , new techniques were brought into play to combine the signals from multiple antennas on the ground into one, more powerful signal, in a kind of an antenna array.
Also, in Australia, the Parkes Radio Telescope was brought into the array in time for the fly-by of Neptune in In the United States, the Very Large Array in New Mexico was brought into temporary use along with the antennas of the Deep Space Network at Goldstone.
Electrical power is supplied by three MHW-RTG radioisotope thermoelectric generators RTGs. They are powered by plutonium distinct from the Pu isotope used in nuclear weapons and provided approximately W at 30 volts DC when the spacecraft was launched.
Plutonium decays with a half-life of The RTG thermocouples , which convert thermal power into electricity, also degrade over time reducing available electric power below this calculated level.
By 7 October the power generated by Voyager 1 and Voyager 2 had dropped to The level of power output was better than pre-launch predictions based on a conservative thermocouple degradation model.
As the electrical power decreases, spacecraft loads must be turned off, eliminating some capabilities. There may be insufficient power for communications by The Voyager primary mission was completed in , with the close flyby of Neptune by Voyager 2.
The Voyager Interstellar Mission VIM is a mission extension, which began when the two spacecraft had already been in flight for over 12 years. The panel found that the VIM "is a mission that is absolutely imperative to continue" and that VIM "funding near the optimal level and increased DSN Deep Space Network support is warranted.
The main objective of the VIM is to extend the exploration of the Solar System beyond the outer planets to the outer limit and if possible even beyond.
The Voyagers continue to search for the heliopause boundary which is the outer limit of the Sun's magnetic field.
Passing through the heliopause boundary will allow the spacecraft to make measurements of the interstellar fields, particles and waves unaffected by the solar wind.
The entire Voyager 2 scan platform, including all of the platform instruments, was switched off in All platform instruments on Voyager 1 , except for the ultraviolet spectrometer UVS  have also been switched off.
The Voyager 1 scan platform was scheduled to go off-line in late but has been left on to investigate UV emission from the upwind direction.
UVS data are still captured but scans are no longer possible. Gyro operations ended in for Voyager 2 and in for Voyager 1. Gyro operations are used to rotate the probe degrees six times per year to measure the magnetic field of the spacecraft, which is then subtracted from the magnetometer science data.
The two spacecraft continue to operate, with some loss in subsystem redundancy but retain the capability to return scientific data from a full complement of Voyager Interstellar Mission VIM science instruments.
Both spacecraft also have adequate electrical power and attitude control propellant to continue operating until around , after which there may not be electrical power to support science instrument operation; science data return and spacecraft operations will cease.
By the start of VIM, Voyager 1 was at a distance of 40 AU from the Earth while Voyager 2 was at 31 AU. The spacecraft began VIM in an environment controlled by the Sun's magnetic field with the plasma particles being dominated by those contained in the expanding supersonic solar wind.
This is the characteristic environment of the termination shock phase. At some distance from the Sun, the supersonic solar wind will be held back from further expansion by the interstellar wind.
The first feature encountered by a spacecraft as a result of this interstellar wind—solar wind interaction was the termination shock where the solar wind slows to subsonic speed and large changes in plasma flow direction and magnetic field orientation occur.
Das Programm kam mehrmals aus Budgetgründen in Bedrängnis, da der Betrieb der Sonde pro Jahr mehrere Millionen US-Dollar kostet Personal, DSN -Zeit usw.
Das Voyager-Programm ist auch eines der wenigen Programme, die den Weiterbetrieb der Meter-Antennen und die zugehörige Empfangstechnik erfordern.
Internationale Proteste und die besondere Stellung von Voyager 1 und Voyager 2 verhinderten stets die komplette Einstellung des Programms, das inzwischen als echtes Langzeit-Experiment gelten kann, wobei einige Budgetkürzungen hingenommen werden mussten.
Viele der Projektingenieure arbeiten seit Jahrzehnten für das Projekt und stehen vor der Pensionierung. Sollten die Sonden weiterhin intakt bleiben und die Finanzierung gewährleistet sein, wird die Dauer der Mission begrenzt durch die nachlassende elektrische Leistung der Radionuklidbatterien , die mit dem Abstand schwächer werdenden Funksignale und — weniger kritisch — den Hydrazinvorrat für die Lageregelungsdüsen.
Ab bzw. Der Funkkontakt könnte bis bestehen bleiben. Voyager 1 und ihre Schwestersonde Voyager 2 zogen besonders während ihrer frühen Missionsphase viel Aufmerksamkeit auf sich.
