EIRP – Definition and Pronunciation
What is EIRP?
Effective isotropic radiated power (EIRP) is a measure of the signal strength that a satellite transmits towards the earth, or an earth station transmits towards a satellite, expressed in dBW. Also, the arithmetic product of the power supplied to an antenna and its gain.
Examples of EIRP
Similarly, the application of low power density waveforms has likewise enabled the use of smaller antennas and lower performance pointing systems while still maintaining off-axis Effective Isotropically Radiated Power (EIRP) density within prescribed limits.
From “Aeronautical Mobility Services”.
These spot beams provide high signal strength and signal gain (Effective Isotropically Radiated Power [EIRP] and G/T), allowing the satellite to close links to small aperture earth stations at high data rates with reasonable rain fade margin, to provide acceptable overall link availability.
From “High Throughput Satellites (HTS) and KA/KU Spot Beam Technologies”.
The SART must be designed to conform to all applicable regulations and standards including IMO performance standards, Radio Regulations, CCIR Recommendations and IEC standards: Output power (EIRP): not less than 400 mW.
From “SART – Search and Rescue Transponders – Portable VHF Transceivers”.
