3. INTRODUCTION
➢The modern digital computer has been fundamental to the
space exploration program. Computers have profoundly
affected almost every aspect of space technology, including
spacecraft design, celestial mechanics, mission control, and
the gathering and processing of data generated by the
spacecraft
➢Indeed the evolution and growth of computer technology
is suggestively parallel to the growth in space technology.
4. DESIGNING SPACE SHIPS
❑Spacecraft has to endure various threats so the computer
designs many part and customizes it with the help of
technicians.
❑To check the spaceships capability the computer organizes
many test and the data of the test are stored
5. CALCULATIONS
▪Space mission needs calculations of trajectory propulsion
which the computer recognizes and prepares the data such
as the amount of fuel or the pathway of the spacecraft.
▪The navigation of the spacecraft is done by the computers
and also it monitors the spacecraft 24/7 so that no error
occurs.
6. ROVERS
oThe landing of the rover is also controlled by the computer
oThe rover sends photos and specimen data to computer
which it stores for research.
oAlso many thermal cameras and special Equipments which
are regularly monitored by the computer.
7. RESULTS DATA
✓The results data are very valuable as it can be stolen if it
was a paper copy.
✓The computer helps us here also. It stores the data and
information.
✓These data and info are organized and kept so that
researchers can use it easily in future.

9. Introduction to GPS
• The Global Positioning System, originally
Navstar GPS, is a satellite-based
radionavigation system owned by the
United States government and operated
by the United States Space Force.
• The GPS project was started by the U.S.
Department of Defense in 1973, with the
first prototype spacecraft launched in
1978 and the full constellation of 24
satellites operational in 1993.
10. History of GPS
• When the Soviet Union launched the first artificial
satellite (Sputnik 1) in 1957, two American physicists,
William Guier and George Weiffenbach, at Johns
Hopkins University’s Applied Physic Laboratory (APL)
decided to monitor its radio transmissions.[19] Within
hours they realized that, because of the Doppler
effect, they could pinpoint where the satellite was
along its orbit.
• The GPS project was started by the U.S.
Department of Defense in 1973, with the first
prototype spacecraft launched in 1978 and the
full constellation of 24 satellites operational in
1993.
11. How it works? 🤔
• The GPS receiver calculates its own position and time based
on data received from multiple GPS satellites. Each satellite
carries an accurate record of its position and time and
transmits that data to the receiver.
• The satellites carry very stable atomic clocks that are
synchronized with one another and with ground clocks. Any
drift from time maintained on the ground is corrected daily.
In the same manner, the satellite locations are known with
great precision. GPS receivers have clocks as well, but they
are less stable and less precise.
• Since the speed of radio waves is constant and independent
of the satellite speed, the time delay between when the
satellite transmits a signal and the receiver receives it is
proportional to the distance from the satellite to the receiver.
At a minimum, four satellites must be in view of the receiver
for it to compute four unknown quantities
12. Some of the GPS
satellites
• Navstar-7
• OPS 9794
• USA-10
• SV05

16. AI assistance in missions
● Future space technologies will rely
heavily on robotics and AI to assist
human teams of astronauts.
● Researchers hope that robots will
be able to perform maintenance
and repairs on existing space
stations while aiding scientists with
data collection and analysis.
NOTE !!!!
TheInternational Space

20. Commercial Space Travel
Commercial space travel is still a fairly
sci-fi idea, even with modernspace
technology.However,companies like Jeff
BezosBlueOriginandRichardBranson’s
Virgin Galactic aim to create this very
thing, and sooner than youmight expect.
Virgin Galactica has allegedly already
taken upto 600 deposits for passengers
bookedonthe first commercial flight
that could take off in the next few years.
