AR Provides Power Amplifier To Help Re-Establish Connection With ISEE-3 Spacecraft

ISEE-3 Spacecraft

Souderton, PA — October 14, 2014 —AR RF/Microwave Instrumentation is proud to support the team of citizen scientists that is working to re-purpose a probe launched by NASA in the 1970s. NASA abandoned the probe due to budget limitations, but a group of citizen scientists has found a way to make it useful again.

On August 12, 1978, the International Space/Earth Explorer 3 (ISEE-3) spacecraft was launched as part of a mission to study the interaction between the earth’s magnetic field and the solar wind. ISEE-3 achieved a number of milestones during the 36 years in which it monitored the particles and fields between the earth and its sun. With the news that NASA could not afford to recover the spacecraft, a group of retired and active aerospace engineers as well as a number of space enthusiasts banded together to revive the vintage spacecraft. Their goal, known as the ISEE-3 Reboot, is to use ISEE-3 to gather information for citizen science. The team has raised almost $160,000 to date through crowdfunding.

One of the hurdles the group had to overcome was that the equipment necessary to transmit signals to the spacecraft had been decommissioned in 1999. The equipment is far too expensive to replace, but AR RF/Microwave Instrumentation, along with several other companies, stepped in to help. A power amplifier was needed and AR provided a 700 W transmitter. The Model 700S1G4 is a portable, self-contained, air-cooled, broadband, completely solid-state amplifier designed for applications where instantaneous bandwidth, high gain, and linearity are required. It’s designed to operate at S-Band frequencies ( GHz for this application).
