Space Solutions
Space orbit communications has played a pioneering role in long range communications for 4 decades. Alongside the obvious Tv and phone communication; satcom systems have engaged in many Defence and Disaster monitoring uses.
Communication side of the structure is a mix of transponders, antennas,,switching systems,and control communication links to ground based sites.. Size and weight limitations affect bandwidth and data delivery methods for each reqt around the world. Small aperture antennas (VSAT) are utilised in many applications to link to marine, land and airborne systems wu=ith antenna sizes to 1.5m and data rates of up to 5MBps - which is often a contraining limitation in many reqts.
Ultra high reliability reqts of space orbit components leads customer to value a strong heritage in the market with a strong track record of operation success. More recently as lower orbit reqts have expanded and the market strives for cost reduction across all areas, companies have started to utilise more COTS componnets and operate a rigorous system screening prior to launch at the top level of the BOM rather than a high number of low value add screening exercises on all flight components.
Microwave Marketing support a number of suppliers working on fully space approved and COTS levels of component supply., with many of our suppliers able to offer both heritage and COTS based solutions. Verification is often specified to MIL Standard 883 , critical levels of performance are verified for leak testing, temperature cycling,acceleration,die shear,PIND test,bond pull of inter-connects, X-ray and others. Solderability levels typically assessed to J standard.
