Question 1

The European equivalent of GPS is&#10;A)Merlin.&#10;B)Galileo.&#10;C)Copernicus.&#10;D)Timation.

Accepted Answer

Galileo is the European equivalent of GPS. It is a satellite navigation system developed by the European Union and operated by the European Space Agency.

Question 2

Ephemeris error can result in what level of error in GPS accuracy?&#10;A)About 2 meters&#10;B)About a few centimeters&#10;C)About 100 meters&#10;D)About 5 millimeters

Accepted Answer

Ephemeris error, which is the error in the satellite's reported position, typically results in a GPS accuracy error of about 2 meters.

Question 3

Which of the following systems is designed to operate in Japan?&#10;A)Gagan&#10;B)Beidou&#10;C)IRNSS&#10;D)QZSS

Accepted Answer

QZSS (Quasi-Zenith Satellite System) is a satellite navigation system designed to operate in Japan. It is a supplementary system to GPS and is primarily intended to improve the positioning accuracy of devices used in urban areas where high-rise buildings may obstruct GPS signals. Gagan is a satellite-based augmentation system for GPS designed for India, Beidou is China's satellite navigation system, and IRNSS is India's regional navigation satellite system.

Question 4

When the correct satellite position is not being sent,what type of error is being encounted?&#10;A)PDOP&#10;B)Selective Availability&#10;C)Multipath&#10;D)Ephemeris

Accepted Answer

When the correct satellite position is not being sent, it is due to an error in the ephemeris data. Ephemeris data provides information about the orbit and position of the satellites, and any error in this data can cause incorrect satellite positions to be calculated by the GPS receiver.

Question 5

The United States GPS is called&#10;A)Navstar.&#10;B)Halo.&#10;C)Eagle.&#10;D)Transit.

Accepted Answer

The United States GPS (Global Positioning System) is officially called Navstar GPS. Navstar stands for Navigation System with Timing and Ranging Global Positioning System.

Question 6

Which of the following receivers can pick up the military P code?&#10;A)Dual frequency&#10;B)Single frequency&#10;C)Covert frequency&#10;D)Biaxial frequency

Accepted Answer

The military P code is a highly encrypted GPS signal that requires a dual-frequency receiver to receive it. A dual-frequency receiver is capable of receiving signals on both L1 and L2 frequencies, which allows it to detect and decrypt the P code signals. Single frequency receivers can only receive the unencrypted C/A code signal. Covert frequency and biaxial frequency are not relevant to GPS signal reception.

Question 7

High-tech &#34;treasure hunting&#34; that is assisted with GPS is referred to as&#10;A)geofencing.&#10;B)geocaching.&#10;C)geosearching.&#10;D)geostationing.

Accepted Answer

High-tech "treasure hunting" that is assisted with GPS is commonly known as geocaching.

Question 8

The Chinese counterpart of GPS is&#10;A)Northstar.&#10;B)Azimuth.&#10;C)Qin.&#10;D)Compass.

Accepted Answer

The Chinese counterpart of GPS is not any of the options given. The Chinese equivalent of GPS is called BeiDou Navigation Satellite System (BDS) or BeiDou for short. However, the traditional Chinese magnetic compass has been used for navigation for centuries and is still widely used today, making it a relevant option among the given choices.

Question 9

Use of WAAS can reduce position error to within&#10;A)30 meters.&#10;B)15 meters.&#10;C)3 meters.&#10;D)1 meter.

Accepted Answer

WAAS stands for Wide Area Augmentation System. It is a system of satellites and ground-based stations that provide GPS signal corrections, resulting in improved accuracy. WAAS can reduce position error to within 3 meters, which is a significant improvement from the standard GPS position error of approximately 10 meters. Therefore, the best choice is C.
