Juno

Happy Independance Day America 

Coincidence? On July 4th 2016 and after a five year journey the NASA Juno probe will enter into orbit around Jupiter. The mission’s principal goal is to understand the origin and evolution of Jupiter, teasing out the mysteries that lie beneath the dense Jovian cloud cover, secrets that may help unravel the fundamental processes and conditions that governed our solar system during its formation.

With its suite of science instruments, Juno will investigate the existence of a solid planetary core, map Jupiter’s intense magnetic field, measure the amount of water and ammonia in the deep atmosphere, and observe the planet’s auroras and relay the data back to Earth.

uno will let us take a giant step forward in our understanding of how giant planets form and the role these titans played in putting together the rest of the solar system.

On board the Juno probe is a deep space transponder that is crucial in relaying the mission data back to Earth. It is this transmitter and this is where TRAK can claim to have played its part with the Ka-Band high power isolators that were supplied to Thales Alenia Space almost years ago.

  • Mission Timeline
    • TRAK products supplied for integration – September 2010
    • Launch – August 5, 2011
    • Deep Space Maneuvers – August/September 2012
    • Earth flyby gravity assist – October 2013
    • Jupiter arrival – July 2016
    • Spacecraft will orbit Jupiter for 20 months (37 orbits)

All going well and when the last bit of data has been streamed to Earth, in February 2018, and the 37th of Juno’s allotted orbits is done, Juno, the fastest ever planetary space vehicle will light its engine one last time on a planned de-orbit; plunging into the boiling atmosphere of the planet and ending its historic miasion.

Jupiter is the 8th planetary and interplanetary body orbiter/lender that TRAK products have been supplied for.

TRAK has been contracted by an EU customer to supply S-Band space qualified high power isolators for the SSPAs that will be used aboard JCSAT17.

The isolator has been designed to incorporate a TRAK’s solid TNC long barrelled connector and a custom I/P input interface and will be flight screened and supplied in the Autumn of 2016 for JCSAT17.

JCSAT17 is an S band satellite that is being designed to operate well in excess of 15 years. The satellite will include a flexible processor that will allow its operator, SKY Perfect JSAT Corporation (SJC) to redirect, if required, capacity to concentrate on other high-volume events or disaster relief efforts.

JCSAT17 is the eighth satellite SJC has awarded to Lockheed Martin, beginning with NSAT-110, JCSAT-9 through JCSAT-13 and most recently JCSAT-110R. The satellite will be manufactured in Denver, Colorado and delivered in 2019.

TRAK operates a comprehensive high power test facility comprising a suite of thermal vacuum chambers which, when combined with SSPA and TWTA RF sources enables TRAK to undertake high power TVAC testing at a minimum of 150W CW from 1000 to 18000 MHz and 400W CW from 8.0 to 18.0 GHz.

Over the past 2 decades TRAK has supplied over 3000 flight qualified high power coaxial isolators and circulators operating in UHF, L, S & C-Bands into programs including.
