Q1How is position fixing achieved using satellites?Asimultaneous bearings from a number of satellitesBrange and bearing from each known satellite's positionCsimultaneous ranges from a number of satellites.
Q2What does DGPS refer to?Athe time difference between the transmission of the satellite's coded signal and the time that it is received at the aircraftBthe time difference between the satellite and the aircraft GPS unit transmitting the same code point on the signalCthe correction applied to the 'raw' GPS position to obtain a more precise position.
Q3What prevents the satellites of GPS and GLONASS from colliding?Athe GPS orbit is at 55° to the equator while the GLONASS is at 60°Bthe GPS satellite orbits are 1200 km higher than the GLONASS orbitsCGLONASS has only three orbital planes while GPS has six orbital planes.
