QUESTION: 1

Solution:
QUESTION: 2

### For a star at its upper transit, the local sidereal time is equal to

Solution:

When star is at its upper transit, Hour angle (H) is equal to zero.

QUESTION: 3

### The limiting minimum declination of a circumpolar star having latitude 40° N is

Solution:

The declination of circumpolar star is always greater than colatitude of the place of observation, so limiting delineation = colatitude = 90° - 40° = 50°

QUESTION: 4

The relationship between tropical year TY and sidereal year SY is

Solution:

Tropical year = 365.2422 mean solar days.
Sidereal year = 365.2564 mean solar days.

QUESTION: 5

Solution:
QUESTION: 6

Satellite station S is established during a triangulation survey as shown in fig. The angle α is equal to

Solution:
QUESTION: 7

Which of the following statements about photogrammetric surveying is correct?

Solution:
QUESTION: 8

Consider the following statements associated with triangulation survey
1. In triangulation survey unknown distances between stations are determined using tacheometric relations.
2. The triangulation station at which astronomical observations are made for azimuths are called Laplace stations
3. In tertiary triangulation, the length of the sides is in the range of 10 to 25 km
4. The length of the base line in primary triangulation is 8 to 12 km Of these statements

Solution:
QUESTION: 9

Given that for a triangulation survey
D = distance in km
h = the visible horizon from a station of known elevation above the datum (in metres) if there is no obstruction due to intervening ground, then h is equal to

Solution:
