Orbit

Orbit-position measurement

Orbital positions are determined through the angle measurements of the azimuth and elevation planes of the receiving antenna.

Frequency

Bandwidth measurement

Measurement of the width of a frequency band such that, below the lower and above the upper frequency limits, the mean powers emitted are each equal to 0.5% of the total mean power of a given emission

Spurious emissions measurement

Measurement of the emissions of a frequency or frequencies which are outside the necessary bandwidth and the level of which may be reduced without affecting the corresponding transmission of information

Polarization measurement

Distinction between different types of polarization which include linear (vertical, horizontal) polarization and circular (right-handed, left-handed) polarization Measurement of the tilt angle in the case of linear polarization

PFD (Power Flux Density) measurement

Determination of the PFD using received power, effective antenna apertures and so on

Modulation measurement

Determination of the types of modulation signals

Center frequency measurement

Determination of the center frequencies of carriers

EIRP (Equivalent Isotropic Radiated Power) calculation

Calculation of the EIRP using received power, antenna gains, propagation losses and so on

Spectrum occupancy measurement

Measurement of frequencies and time-related data regarding the occupancy of frequency bands

Broadcasting signal demodulation

Demodulation, recording and storage of received broadcasting signals (video, image and voice)
