A Manufacturer of Unique VHF Radio Noise Products.

 
 

Since its founding in 1972 by a several faculty members of the University of California, San Diego, La Jolla Sciences has been developing and offering a specialized set of instruments for scientific monitoring and research within the radio noise spectrum.

Riometer RIOMETER.  For the measurement of galactic radio noise and for research in upper atmosphere and magnetospheric physics.  Our third generation instrument is all solid state and field proven in Antarctica and the Arctic.  Operating frequencies can be set from 20MHz to 100MHz, wideband or narrow band.  Apart from the traditional role of the Riometers, other applications could include radio noise monitoring, field strength measurements and radio astronomy. Sections of the Riometer can be used for  RF  switching, power linear RF detection, synchronous detection and timing sequences.  Custom modules are produced to order.

ANTENNA.  A portable, rugged wide beam antenna kit has been produced for use with the Riometer to provide a wide beam for vertical monitoring.  The kit is easy to transport and easy to install and has given long term service in Antarctic field sites for many years.  La Jolla Sciences has also been involved in the development of steerable narrow beam arrays used in the Riometer Imaging Systems (IRIS).




PORTABLE NOISE GENERATOR.  This miniature battery operated solid state noise source is calibrated against a standard noise source and is invaluable for all Riometer installations.  With a single level control, it can be used as a steady noise source or can be varied to check the operation of the complete antenna, Riometer, recording system combination in the field.


RELATED PRODUCTS.  La Jolla Sciences has produced a range of power modules for the various installation modes of the Riometer especially the "remote" Riometer option where the Riometer is set at the antenna site away from other equipment at the station.  A Switch/Test unit has been developed for diagnostic trouble shooting of the Riometer. A precision noise generator has been developed and is used as a noise reference source for the portable noise generator.

CUSTOMER LIST.  La Jolla Sciences enjoys relationships with many organizations throughout the world and will provide references if requested (subject to confidentiality limitations).
