IFR NAV - GNNS

What does GNSS stand for?

• Galileo Navigation satellite system

• General Navigation satellite system

• Global Navigation standard satellite

• Global Navigation satellite system

what are the main elements of a GPS system?

• Space segment, User segment, Control segment and Monitor stations.

• Space segment, User segment, Monitor stations.

• Space segment, User segment, Control segment, Monitor stations and Colorado Springs office.

• Space Segment, User segment and Control segment.

how many satellites do you need for RAIM?

• At least 5

• At least 4

• At least 6

• At least 3

The Satellite segment consists of a constellation of:

• At least 24 Satellites plus 1 operational spare, on 8 orbital planes

• At least 24 Satellites plus 3 as operational spares, in 6 orbital planes

• At least 24 Satellites plus 1 operational spare, in 6 orbital planes

• At least 24 Satellites including 3 operational spares, in 8 orbital planes

The GPS uses Triangulation to determine position:

• A minimum of four satellites are required for a two dimensional fix

• A minimum of two satellites are required for a two dimensional fix

• A minimum of three satellites are required for a three dimensional fix

• A minimum of three satellites are required for a two dimensional fix

What does RAIM stand for?

• Receiver Autonomous integrity monitoring

• Receiver Autonomous identity monitoring

• Receiver Automatic integrity monitoring

• Receiver automatic identity monitoring

What do you need to check in regards to GPS before flight.

• Data base Validity

• Location

• Magnetic direction

• all three options

What is data entry error?

• The computer freezes and you can't enter anymore data.

• While entering data an error in the system occurs.

• The Data in the GPS unit is incorrect

• The data input by the pilot is incorrect.

GPS receivers can distinguish between individual satellites using:

• Almanac data of the satellites position in space

• Different frequencies for each satellite

• Directional modulation

• Identifying the pseudo-random code unique to each satellite
