Our first 12U-class satellite has been despatched for launch next month via an ISRO PSLV, our 4th satellite launch of the year! This will be hosting a compelling AOCS; coupling an Aliena Pte Ltd Hall thruster with Aurora Propulsion Technologies resistojets! @SpaceNews_Inc

We're hiring: - Satellite Engineers - Embedded Systems/FPGA Engineers - Senior Electronics/RF Engineer - Supply Chain & Procurements Manager OrbAstro is scaling. Though we keep a low profile, we are a high-impact and high-tech space company achieving disproportionately.

Automation is central at OrbAstro. It allows us to achieve disproportionately. e.g. assembly/integration/testing for our OBC involves measuring ~17k parameters over 60hrs, mostly in vacuum, generating ~93GB of data analysed live by our AI server in our 800teraflop datacentre.

This is Guardian-alpha, a 3U satellite entirely developed by @OrbAstro from the ground up. Launching in June with @momentusspace on a @SpaceX Falcon 9. A lot of innovation: Ultrascale+ OBC, electric propulsion, full ADCS with dual star-trackers, SDR S-band Tx/Rx, long-life EPS...

This comes as standard on our satellite platforms, 3U-16U: orbastro.com/satellites/orb… Be sure to follow us. We’re now revealing what we’ve been building at OrbAstro. Satellite, subsystems, batch production capabilities, testing facilities. There is serious engineering porn coming.

With this available, it makes no sense to the continue with the current convention. EPS failure, due to low cycle lifetime/environ conditions, is one of the primary reasons for early decommissioning.

Here is a mega-controversial one... Today we reveal our modular electrical power systems. Flight-qualified; flight-heritage in June. We went back to first principles. It took dozens of iterations to get here.

Ultrascale+ FPGAs are known to struggle in the radiation environment. With radiation analysis using in-house tools and extensive testing, fault tolerance (SEU/SEL protection) has been implemented on both hardware/software and demonstrated successfully (400krad, 60MeV).

Today we are talking about our “satellite on a board”. Flight-qualified, gaining flight-heritage in June. We've compressed what is typically seven 1U-scale PCBs onto one 80x75mm board.
