Chapter 14, Problem 14.1P

To determine

(a)

Surveying method used for 25 km baseline.

Answer to Problem 14.1P

Static survey

Explanation of Solution

Given information:

A baseline of 25 km with dual frequency receiver

There are two surveying methods; they are static surveying method and rapid static surveying method. Rapid static surveying method is limited for a length of 20 km, whereas the static surveying method is used for larger areas with good observation. So for the baseline length of 25 km we are using static surveying method.

Conclusion:

The surveying method used for baseline of 25 km is static method.

To determine

(b)

Time period for the baseline

Answer to Problem 14.1P

   $70\text{min}$

Explanation of Solution

Given:

A baseline of $\text{25}$ km with dual frequency receiver

Concept used:

Length of a session for baseline of $25\text{km}=20\min +2\text{min/km}$

Calculation:

   $\begin{array}{c}\text{Length of a session for baseline of 25 km}=20\min +2\text{min/km}\times 25\text{km}\\ =\text{70}\text{min}\end{array}$

Conclusion:

The time period for the baseline should be observed is 70 minutes.

To determine

(c)

Epoch rate

Answer to Problem 14.1P

   $\text{15}\sec$

Explanation of Solution

Given:

A baseline of $\text{25}$ km with dual frequency receiver

The epoch rate should be $\text{15}$ seconds for static surveying method and it is used to reduce the number of observations,

Conclusion:

The epoch rate should be used is $\text{15}$ seconds.
