6. Used for specific projects
Commonly restricted by meteorological
factors, such as Wind velocity, direction
etc.,
Two Types (i) Free Balloons
(ii) Tethered Balloons

7. Aircraft

8. Dakota
Speed:240km/hr
Height : 6km to 7 km

9. Avro
Speed:600 km/hr
Height : 8km

10. Cessna
Speed:350 km/hr
Height : 9km

11. Canberra
Speed:560 km/hr
Height : 5km

12. Used for obtaining aerial photographs
Useful for regional coverage and large scale
mapping
Flexibility of altitude in flying and data acquisition
as per need
Important : Maximum Stability, Free from vibrations
and oscillations, fly with a uniform speed, the height
of ceiling.
Types:
(i) Helicopters
(ii) Drones
(iii) Sail Planes are also used for low altitude
photography and television photography.

17. Satellites – Use in Natural resource mapping,
meteorological and communication applications
Free flying orbiting vehicles whose motion is
governed by gravity and atmosphere based Kepler’s
Law
Entire earth or designated portion can be suitably
covered at specified intervals
Least affected by disturbance in atmosphere and
hence their orbits can be properly defined
Also helpful in viewing extraterrestrial bodies
Types (i) Geostationary Satellites
(ii) Sun Synchronous Satellites

18. Geostationary Satellites
Also known as Earth Synchronous Satellites and
the orbit in which these satellites move is called
geosynchronous or geostationary satellite
Placed at a distance of 36,000km above the equator
At this altitude the orbital speed of the satellite is
the same as that of the Earth’s rotation speed.
Satellite cover the same area continuously over
they are flying and information transmission is
rapid
Spatial resolution is poor (1 km)
Used for Weather forecasting and Communication
Purposes

23. GOES 1 (USA) 1310W

24. GMS (JAPAN) 1400E

25. Meteosat (ESA) 00

26. Sun Synchronous Satellites
Provide Global coverage with high resolution
Used for applications in resource surveys and
monitoring
Also called natural resource or polar satellites
Move in low earth orbit at 800-1000km altitude
over or near the north and south poles.
The orbit is known as polar or sun synchronous
orbit, coinciding with the plane of the sun.
Normally passes a particular place at the same
local time after a regular interval of time, providing
repetitive coverage of the place.
