How is the Galileo system characterised (#-satellites, inclination, orbit duration)
- 30 satellites
- 23'260km
- 56° (to the equator)
How is the Beidou system characterised (#-satellites, inclination, orbit duration)
- 30 satellites
- geostationary (~35'000km)
How is the NAVSTAR GPS system characterised (#-satellites, inclination, orbit duration)
- 31 satellites
- 20'180km
- 55° (to the equator)
- 1'575.42 MHz
How many satellites are required (minimum) for a 3D position?
4
--> To compensate for the receiver clock error
Explain the working principle
Satellites transmit pulse modulated signals which are received by a station on the earth. The run time of the signal is used to determine the distance between receiver and satellite. With the signal of multiple satellites (min. 4) the position can be determined precisely (+/- 4m).
Name the 3 segments of GNSS
- User segment = Devices receiving GPS signals
- Satellite segment = Satellites
- Control segment = Control stations ensuring that satellites transmit accurate information.
Name the two types of waypoints
Fly-over-waypoint
Fly-by-waypoint
Difference between Fixed radius transition and radius to fix?
In FRT the turn is initiated before the WPT to the new heading from the WPT
In RF the turn is made from WPT to the other
What precision is required for B-RNAV?
+/- 5 NM from the desired path for 95% of the flighttime
--> Also referred to as RNAV 5
What precision is required for P-RNAV?
+/- 1NM from desired path for 95% of the flight time
--> Also referred to as RNAV 1
