Vigilance

Given the present radio environment in Puerto Rico, constant vigilance is needed over the entire frequency range covered by the Arecibo Telescope. This has two components; (1) spectrum monitoring of the radio emissions due to existing systems both at the observatory and around the island; and (2) keeping a watchful eye on future and developing installations, national and international trends in spectrum usage, and regulatory actions by the various authorities.

Towards achieving these goals, NAIC/AO has set up a round-the clock spectrum-monitoring system, covering up to 10 GHz. In order to check the influence of various spectrum usages within the observatory's receiving bands, Commissioning Task, X111 is currently being scheduled, where the Gregorian receiver and the NAIC correlator is being used to mimic the actual observing condition. More about these and our constant efforts in protecting Radio Astronomy Services (RAS) bands can be found in the listed items below:
