Navigation systems

Which innovation revolutionized maritime navigation by offering the possibility to determine a ship’s longitude?

• The magnetic compass

• Radio direction finders

• The marine chronometer

• The Long-range navigation system

• I don´t know

What source isn't typically used to conclude the real time traffic?

• Weather stations

• Tracking of the movement of mobile phones WiFi signals

• Emergency Services

• Road Sensors

How many satellites does the original GPS satellite system have?

• 24

• 32

• 45

• 63

• trölf

What is the task of the Master Control Station?

• collects telemetry data

• sends commands to satellites

• tracks the satellites

• monitors the system integrity

• I don´t know

What are two basic approaches in the area of the autonomous vehicle navigation?

• 1. Add dozens of sensors to the vehicle to prepare its navigation systems for the inevitable scenario that GPS signals become unavailable.

• Combine GPS with a high-quality on-board Inertial Navigation System (INS), which delivers a high level of short-term accuracy but eventually drifts when it loses touch with external signals

• Program them so that they could tap into the hundreds of signals around us at any point in time, like cellular, radio, television, Wi-Fi, and other satellite signals.

What does ICG and ADAS stand for?

• ICG stands for International Committee on Global Navigation Satellite Systems

• ICG stands for International Connection Group

• ADAC stands for Allgemeiner Deutscher Automobil-Club.

• ADAS stands for Advanced Driving Assistance System

Why can navigation systems contribute to the degradation of infrastructure?

• Because they often displace traffic from main to secondary roads, which are not built to handle heavy traffic

• Because the satellite signals used by navigation systems have a cumulative effect on the structural integrity of roads and bridges over time

Select concerning aspects of modern navigation systems

• Collection of sensitive data

• negative impact on human ability to navigate

• Increased productivity and efficient route planning

What is the satellite program of the European Union called?

• GLONASS

• GALILEO

• NAVSTAR

• GeePeeEss

Which navigation system isn‘t used anymore?

• RDF

• LORAN

• INS
