What is the major advantage of dual-frequency over single-frequency GPS receivers?
A. precise measurements of longer baselines
B. observation of more satellites
C. observation in bad weather conditions
D. measurement in three dimensions - correct answer A. precise measurements of
longer baselines
Dual-frequency GPS receivers collect data that can be used to model the ionospheric
delay and thereby compensate for its effects on the signal. Therefore, they may be
used for baselines of greater length and also require shorter observation times for
comparable precision, as compares to single-frequency receivers.
What method should be used to restore a lost southeast corner of Section 31 in a
typical township?
A. bearing-bearing intersection
B. single proportional measurement
C. double proportional measurement
D. record bearing and distance - correct answer B. single proportional measurement
Since the southeast corner of Section 31 is on the township exterior, single
proportional measurement should be used to reestablish lost corners.
The star Polaris is located in which constellation? - correct answer . Ursa Minor
What is the length of one link of a Gunter chain? - correct answer A Gunter's chain is
66ft in length and is divided into 100 links. Therefore, each link is 0.66ft or 7.92 in
When sighting through a leveled instrument at a distant level rod, curvature of the
earth would have what effect on the rod reading? - correct answer The rod reading
would be greater due to the constant dropping of the Earth's surface from the
horizontal level line.
When sighting through a leveled instrument at a distant level rod, what would be the
effect of refraction on the rod reading? - correct answer The rod reading would be less
because refraction has the opposite effect as curvature.

On a map developed from a Lambert projection, which of the following is true?
A. Meridians converge
B. Parallels are arcs of circles
C. Parallels are uniformly spaced
D. (A), (B), and (C) are true - correct answer D. all of the above
On a lambert projection, meridians are sown as converging straight lines, while
parallels are shown as uniformly spaced arcs of circles.
Which method should be used to restore a lost southwest corner of Section 31 in a
typical township?
A. bearing-bearing intersection
B. single proportional measurement
C. double proportional measurement
D. record bearing and distance - correct answer C. double proportional measurement
Since the Southwest corner of Section 31 is the township corner, double proportional
measurements should be used to reestablish the corner.
Which of the following can be accomplished by the DMD method?
A. Balancing a closed traverse
B. correcting latitude observation
C. correcting longitude observation
D. determining area of a closed figure. - correct answer D. determining area of a
closed figure.
DMD stands for Double Meridian Distance and describes a method for determining the
area of a closed figure.
In a closed traverse with the only significant error in measurement being one angular
error, at which station was the error most likely made? - correct answer The
perpendicular bisector of the line of closure will point the traverse station where the
error was probably made.
A closed traverse has a total length of 2181.14 ft. and an error of closure of 0.37 ft. in
the northing and 0.24 ft. in the easting. What is the ratio of error for the closure?

0.9999424. What is the surface distance, assuming no sea level correction is
necessary? - correct answer 5280.30 ft.
