Test: Tides, Triangulation, Astronomy & Photogrammetric Surveying - 1 - Question 1

For a circumpolar star, declination must be

Test: Tides, Triangulation, Astronomy & Photogrammetric Surveying - 1 - Question 2

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

Detailed Solution for Test: Tides, Triangulation, Astronomy & Photogrammetric Surveying - 1 - Question 2

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

Test: Tides, Triangulation, Astronomy & Photogrammetric Surveying - 1 - Question 3

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

Detailed Solution for Test: Tides, Triangulation, Astronomy & Photogrammetric Surveying - 1 - Question 3

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

Test: Tides, Triangulation, Astronomy & Photogrammetric Surveying - 1 - 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
