Q211.
Which among the following is used to determine the position of an aircraft using very high frequency omnidirectional range (VOR)?

a.

Round trip time of a radial from a single VOR station

b.

Intersection of radials from a single VOR station in different directions

c.

Intersection of radials from a single VOR station with a delay between the signals

d.

Intersection of radials from two different VOR stations

Discuss
Answer: (d).Intersection of radials from two different VOR stations Explanation:Line of position in very high frequency omnidirectional range is called the radial. The line of position consists of a highly directional signal sent by the VOR ground station using a phased antenna array and a reference signal in phase with the directional antenna. The intersection of radials from two different VOR stations is used to determine the position of an aircraft.
Q212.
What is the accuracy range offered by very high frequency omnidirectional range?

a.

50 m

b.

60 m

c.

80 m

d.

90 m

Discuss
Answer: (d).90 m Explanation:Very high frequency omnidirectional range is a short-range radio navigation system. The signals are kept in the line of sight between the transmitter and receiver. It offers an accuracy of 90 m.
Q213.
Which among the following techniques is employed in long range navigation (LORAN)?

a.

Round trip time of a radio pulse

b.

Time difference between two radio pulses

c.

Phase difference between two continuous signals

d.

Phase difference between the transmitter and the receiver

Discuss
Answer: (b).Time difference between two radio pulses Explanation:Long range navigation is a hyperbolic radio navigation system operating at low frequencies. The hyperbolic navigation system in LORAN uses the time difference between radio pulses to locate the object of interest. An electronic clock was employed to generate trigger signals that maintain a fixed delay such as 1 ms between the transmitters.
Q214.
What is the parameter which differentiates LORAN – B from LORAN – A?

a.

Method of extraction of timing

b.

Number of receivers

c.

Number of transmitters

d.

Determination of station location

Discuss
Answer: (a).Method of extraction of timing Explanation:LORAN – B employed phase comparison variation and hence used a different method of timing extraction compared to LORAN A. The disadvantage of LORAN B is that its pulse length was about 40 microseconds and the technique exhibited phase distortion.
Q215.
Which among the following techniques were employed for the identification of pairs in LORAN stations?

a.

Modulation technique

b.

Encoding scheme

c.

Phase comparison between signals

d.

Pulse repetition frequency

Discuss
Answer: (d).Pulse repetition frequency Explanation:LORAN stations are composed of a master station and two slave stations. Each pair typically broadcasted over the following frequencies of 1.75, 1.8, 1.85, or 1.9 MHz. However, the location of stations is such that it allowed a particular station to pick up signals from at least three stations. Thus to detect to pairs of signals, pulse repetition frequency comparison is employed.
Q216.
Which among the following is essential for geo-location using IP address?

a.

Database of registration lifetime of IP packets

b.

Database of IP addresses

c.

Database of routing path

d.

Database of port address

Discuss
Answer: (b).Database of IP addresses Explanation:Geo-location software translates an IP address into a geo-location and provides the name of a country, city, or zip code. The software exploits the IP address of the sender included in the IP packet. There are a number of geo-location databases that offer different levels of accuracy.
Q217.
Which among the following are sources for constructing an IP database?

a.

Network routing information

b.

Data mining

c.

Regional Internet registry

d.

Data scrubbing

Discuss
Answer: (d).Data scrubbing Explanation:The primary source of the IP address database is the regional internet registries that assign the IP addresses to organizations within their service area. Network routing information extracted at the endpoint of an IP address, data mining, and data provided by Internet Service Providers are useful for constructing the IP database.
Q218.
Which among the following is an application of geo-location software?

a.

Regional licensing

b.

Firewall

c.

Address translation

d.

Diagnostic tools

Discuss
Answer: (a).Regional licensing Explanation:Internet services such are live streaming sporting events, or online streaming of television shows and music might be permitted to broadcast only over certain licensed territories. Geolocation is applied to avoid license violations. Fraud detection, Geomarketing, and gaming are other regions of interest.
Q219.
Very High Frequency Omnidirectional Range begins with transmission of frequency modulated signal.

a.

True

b.

False

c.

May be True or False

d.

Can't say

Discuss
Answer: (b).False Explanation:Very High Frequency Omnidirectional Range begins with transmission of amplitude modulated signal with a constant frequency. The transmitted signal passes through a set of antenna in a circle introducing frequency modulated Doppler onto the received signal. The relative phase angle between amplitude modulated signal and frequency modulated signal is employed to find the location of the source.
Q220.
Which among the following is not an outcome of destination location addressing?

a.

Reduced interference

b.

Reduced power consumption

c.

Reduced handovers

d.

Reduced dropped calls

Discuss
Answer: (c).Reduced handovers Explanation:Destination location addressing propagates via only known nodes in a path to reach the destination. This prevents signal propagation from running off course and optimizes power consumption. It also results in the reduction of interference and dropped calls by combining the knowledge of geolocation, velocity vector, and planned path.
