Committee on Radio Astronomy Frequencies

The Committee on Radio Astronomy Frequencies (CRAF) is a committee of the European Science Foundation (ESF).

Monitoring facilities at Nançay Observatory

Fixed monitoring station.

Azimuth range (in °): 0 - 360
Elevation range (in °): 0 - 90

Characteristics of the facility:

Frequency range Frequency resolution Antenna gain Sensitivity Omni-directional antenna
(MHz) (kHz) (dBi) (dBW/MHz)

100 - 500 0.3 - 1000 8 -175¹ no²
1000 - 3500 0.3 - 1000 21 at 1000 MHz
-175¹ no²
32 at 3500 MHz

Notes:

¹: calculated using Recommendation ITU-R RA.769 with T_sys ~300K, bandwidth 1 MHz, and integration time of 1 second.

²: The antenna is not omnidirectionnal, but may be pointed in every sky direction.
