HIPAS Observatory
Encyclopedia
The HIPAS Observatory is an ionospheric heater
, which can radiate 70 MW ERP at either 2.85 MHz or 4.53 MHz. located 30 miles Northeast of Fairbanks, Alaska
, in the small community of Two Rivers
. It is located at: 64° 52’ 19" N latitude and 146° 50’ 33" W longitude and operates year-round. The HIPAS Observatory is operated by the UCLA plasma physics laboratory.
The HIPAS facility is engaged in the study of the ionosphere
through the use of high power radio transmission as well as a LIDAR
(LIght Detection And Ranging ) instrument. The facility is home to several projects with some interesting equipment, including:
Some of the research conducted at HIPAS is similar to the controversial HAARP
project, and so the staff of the facility sometimes have to answer the same questions from the public. The facility has been shut down and much of the equipment sold off as surplus during the Spring of 2010.

Ionosphere
The ionosphere is a part of the upper atmosphere, comprising portions of the mesosphere, thermosphere and exosphere, distinguished because it is ionized by solar radiation. It plays an important part in atmospheric electricity and forms the inner edge of the magnetosphere...
