3. INTRODUCTION
Global positioning system (GPS)is a navigational
system, operated and controlled by the U.S.
department of defense, which allows users to
determine position, velocity, and time using GPS
receivers and radio signal from GPS.
The global positioning system finds its application
in almost the industries. Mining is the no more
exception for that. The usage of GPS in mine
surveying both for O/C and U/G projects is well
known. The other usages include mobile equipment
tracking, shovel, dozer and drill positioning etc.

4. HOW GPS WORKS
GPS satellite transmits timing pulses 1000 times per
second. The pulses are mixed with a faster digital signal
to create “spread spectrum” signal. GPS satellite also
transmits information about their location.
The signal is transfer in form of two type :-
1. Almanac
2. Ephemeris
This data is sent out at rate of 50bits/sec.

6. USES OF GPS
The GPS application generally falls into 5 major categories:
1. Location - determining position.
2. Navigation - getting from one location to another.
3. Tracking - monitoring object or personal movement.
4. Mapping - creating maps of the world.
5. Timing - brining precise timing to the world.
• Some other application
Mining, aviation, surveying, marine, recreation
and military.

7. Uses of GPS in mining
The following area in mining where GPS is used.
1. Mine surveying
2. Establishing national grid lines at new areas
3. Establishing boundaries in case of mining lease area.
4. Documentations of the land.
5. Establishing control stations.
6. Shovel positioning
7. Mobile equipment
8. Drill positioning
9. Dozer positioning

8. Problems with GPS usage and solution
1.Initial high investment.
2.Accuracy.
3.System of co-ordinates.
4.Need of clear view of sky.
5.Training the present generations to face
6.Problem in deep pit mining.

9. Conclusion
GPS can be very well used in Indian mining industry. research and
development project to assess its possible usage in mining projects
can be organized jointly by vendors, research institutions and
mining industry. GPS is a powerful surveying tool, which can
provide on its own or in combination with other ground survey
technique the required speed, accuracy and economy in surveying
of large mining or opencast block.
