Chapter 14, Problem 14.1P

a.

To determine

The survey method to be used.

Answer to Problem 14.1P

Rapid static survey method

Explanation of Solution

Given:

  $5km$ baseline.

Concept Used:

Global navigation satellite systems-static surveys

Calculation:

For a $5km$ baseline using a dual frequency receiver the rapid static method is used because it is suitable for observing the baselines up to $20km$ length under the good observation conditions.

Conclusion:

Therefore, Rapid static survey method is used.

b.

To determine

The time period of the observation of the baseline.

Answer to Problem 14.1P

  $15\min$

Explanation of Solution

Given:

  $5km$ baseline.

Concept Used:

Global navigation satellite systems-static surveys

Calculation:

  

From the above table dual frequency for $5km$ baseline is given by:

Length for $5km$ baseline

  $\begin{array}{l}Lengthfor5km baseline=10\min +1\min /km\\ Lengthfor5km baseline=10\min +1\min /km\times 5\\ Lengthfor5km baseline=15\min \end{array}$

Conclusion:

Therefore, time period for the baseline to be observed is $15\min$ .

c.

To determine

The epoch rate to be used.

Answer to Problem 14.1P

  $5\sec$

Explanation of Solution

All receivers should be set to collect data at same epoch rate bust usually it is set to $5\sec$ which is considerable smaller than rate of the given static session.
