QUESTION: 1

For a circumpolar star, declination must be

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: 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
