E2A01-2012: What is the direction of an ascending pass for an amateur satellite?

From south to north

From west to east

From east to west

From north to south



E2A02-2012: What is the direction of a descending pass for an amateur satellite?

From north to south

From west to east

From east to west

From south to north



E2A03-2012: What is the orbital period of an Earth satellite?

The time it takes for a satellite to complete one revolution around the Earth

The point of maximum height of a satellite's orbit

The point of minimum height of a satellite's orbit

The time it takes for a satellite to travel from perigee to apogee



E2A04-2012: What is meant by the term mode as applied to an amateur radio satellite?

The satellite's uplink and downlink frequency bands

The type of signals that can be relayed through the satellite

The satellite's orientation with respect to the Earth

Whether the satellite is in a polar or equatorial orbit



E2A05-2012: What do the letters in a satellite's mode designator specify?

The uplink and downlink frequency ranges

Power limits for uplink and downlink transmissions

The location of the ground control station

The polarization of uplink and downlink signals



E2A06-2012: On what band would a satellite receive signals if it were operating in mode U/V?

435-438 MHz

144-146 MHz

50.0-50.2 MHz

29.5 to 29.7 MHz



E2A07-2012: Which of the following types of signals can be relayed through a linear transponder?

All of these choices are correct

FM and CW

SSB and SSTV

PSK and Packet



E2A08-2012: Why should effective radiated power to a satellite which uses a linear transponder be limited?

To avoid reducing the downlink power to all other users

To prevent creating errors in the satellite telemetry

To prevent the satellite from emitting out of band signals

To avoid interfering with terrestrial QSOs



E2A09-2012: What do the terms L band and S band specify with regard to satellite communications?

The 23 centimeter and 13 centimeter bands

The 2 meter and 70 centimeter bands

FM and Digital Store-and-Forward systems

Which sideband to use



E2A10-2012: Why may the received signal from an amateur satellite exhibit a rapidly repeating fading effect?

Because the satellite is spinning

Because of ionospheric absorption

Because of the satellite's low orbital altitude

Because of the Doppler Effect



E2A11-2012: What type of antenna can be used to minimize the effects of spin modulation and Faraday rotation?

A circularly polarized antenna

A linearly polarized antenna

An isotropic antenna

A log-periodic dipole array



E2A12-2012: What is one way to predict the location of a satellite at a given time?

By calculations using the Keplerian elements for the specified satellite

By means of the Doppler data for the specified satellite

By subtracting the mean anomaly from the orbital inclination

By adding the mean anomaly to the orbital inclination



E2A13-2012: What type of satellite appears to stay in one position in the sky?

Geostationary

HEO

Geomagnetic

LEO
