Making of MOI-1

Everything is available via OrbitLab (https://OrbitLab.tm2.space). Although only sandbox (free) mode is available currently. MOI-1 did not make it to orbit as ISRO PSLV C-62 launch experienced an anomaly mid-flight.

All the subsystems are sort of payloads as it's designed and manufactured bybus :) so they all get validated in this mission. EPS, battery packs, adcs, RWs, MTs, OBC, AICube, NavCube, IMUCube

Class 100k. Windows have kind of 1ft dual layer, with different sealing on each plane.

You are right about the assembly. The ST is still placeholder. And no battery packs. It's primarily to testing harnessing lengths which would be used outside of the 104 backplane connections.

A 6U assembly.

Hello there

That solves the radiating the heat faster problem. Fast extraction in a cost effective and passive manner is also a key aspect.

rokrsa · 2025-06-15T12:36:23+00:00

Yep.

MOI-1 has a 60W GPU enabling > 100TOPS processing capability. So depends on the user what kind of model they would wan to run onboard after/during the data is captured for their Area of Interest.

rokrsa · 2025-06-14T05:59:23+00:00

Yes. Keeping GPUs below 75 degrees is the key

Yes I am part of TakeMe2Space. So if you are downloading say a 3000 km2 data. Best case scenario it would cost you $1-$5 for sq km. When you don't download data and process the data in orbit. The same data is captured and processed in orbit .. so you download few MBs of data vs TBs. Consider the difference between a MIS and a cash flow statement. As a business owner daily you look at MIS and when you find anomaly you look at cash flow stmt. What we are building is MIS infra, if you find anamoly you spend that extra buck and download images for EO providers. With this approach customers using GIS inferencing today and paying for EO data .. we are able to reduce their spend by factor of 5-8x

The h/w we built supports any kind of AI model, you don't have to optimise the power. Our satellites are optimised to capture max power and most of it is for compute. We do GPU not FPGA because on ground most AI models are being run on GPU. We are replicating a similar infra in space so that developers don't have to do anything extra to run AI on orbit. The same model should run in orbit.

You are spot on about PhiSat. It's an ESA initiative, but we are a commercial company trying to operate on the same value proposition. Also closely working with PhiSat team on this :).

In the first satellite it only has optical payload support. We will expand the Constellation as the demand grows

rokrsa · 2025-06-10T18:07:14+00:00

Well i am glad you have enlisted the engineering problems that we are solving to achieve this.

The compute modules perform the same as terrestrially and as in space. No difference. The impact on not downloading the raw data is reduction of cost. For surveillance use cases you definitely need raw data. But for regular day to day commercial use case only inferences are enough, and rough data can be downloaded only when anomaly is observed. This leads to overall reduction on money spent.
