CONS 127 MIDTERM COMPLETE TEST PAPER
WITH CORRECT ANSWERS
◉ Cities Map Scale.
Answer: map scale used for city neighborhoods
◉ geodetic marker.
Answer: -a way of mapping the Earth's surface
-give us accurate information on their relative and absolute position,
and by triangulation, the points are used to find other points
◉ critical measurement to obtain an accurate longitude.
Answer: time
◉ 3 devices that can measure distances at different scales.
Answer: microscopes, telescopes and satellites
◉ orbit.
Answer: a curved path around an object in space, created by
gravitational attraction between two objects
,◉ space.
Answer: an area of low air pressure and density that is hundreds of
kilometers up into the sky and atmosphere
◉ orbit used to monitor weather.
Answer: Geostationary orbits
◉ orbit used for GPS tracking.
Answer: far elliptical orbit
◉ orbit best for getting to and returning from space easily.
Answer: Low earth orbit
◉ In ocean navigation, which is easier to calculate - latitude or
longitude?.
Answer: Latitude is easier to calculate, as you can use the stars to
measure your position. Every star reaches the same height ever
night, so the height of the star will change as your latitude position
on Earth changes. To measure latitude, it is best to look at the North
star in the Northern Hemisphere.
◉ orbit type that most remote sensing satellites are in.
Answer: far elliptical orbit
, ◉ how is GNSS different from GPS?.
Answer: geostationary navigation satellite system differs from a GPS
because GPS is actually the USA's version of a GNSS system, similar
to how GLONASS is by Russia and GALILEO is by Europe.
◉ minimum number of satellite needed for an accurate positional
location.
Answer: 3 to find a positional location, but 4 is preferred for a truly
accurate measurement
◉ 2 types of information are sent by GNSS satellites to receivers that
allow for the determining of a position.
Answer: Almanac and ephemeris
◉ 2 types of dilution of position error and how they can be
minimized.
Answer: -position of satellites and obstructions
-can be minimized by a differential GPS, which uses a reference
station
◉ distance from a GNSS satellite to a receiver is measured this way.
Answer: -calculation of the speed of light
