Our offerings
The Satellize space stack: payload, ground segment, mission control, training.
Satellize delivers complete sovereign space programs, not point hardware. Our offering is a layered stack — every layer can be bought standalone, but the value is in the integration. We build the bus, integrate the payload, ship the antennas, write the mission-control software, certify the operators, and hand the keys over. What follows is the full stack, layer by layer.
1. Satellite buses (10–200 kg, modular)
Our bus platforms span CubeSat-class missions (10–25 kg) through ESPA-class small satellites (up to 200 kg). All buses share a common avionics core: redundant flight computers, software-defined radios, a fault-tolerant power architecture and a cold-gas or electric propulsion option for orbit maintenance. Modularity matters because sovereign programs evolve — a country's first satellite is rarely its last, and the industrial muscle memory built on bus #1 is the foundation for everything that follows. Heritage: ExseedSat 1 (2018) and ExseedSat 2 (2019) were both built on the lineage of these platforms.
2. Payloads (optical, SAR, hyperspectral, RF, comms)
We integrate four families of payload, sourced or co-developed with sovereign-friendly suppliers:
- Optical imaging — sub-metre to multi-metre ground sample distance, panchromatic and multispectral, day-pass cadence configurable by orbit choice.
- Synthetic-aperture radar (SAR) — X-band and C-band, all-weather, day-and-night imaging for maritime, defence and disaster response.
- Hyperspectral — for agriculture, forestry, mineral exploration and environmental monitoring; tens to hundreds of bands.
- RF and communications — sovereign broadband, narrowband IoT, AIS receivers, signal-intelligence collection, and PNT augmentation.
3. Ground segment (your antennas, on your soil)
A satellite is only as sovereign as the ground station it talks to. Our ground segment includes the dishes (S/X/Ka and UHF/VHF as required), the modems and baseband processing, the cryptographic key-handling vaults, the network gateways into your existing C2, and the physical site security. We design for redundancy across at least two geographically separated sites on your territory, so no single antenna is a single point of failure.
4. Mission-control software (sovereign, source-available)
Off-the-shelf western mission-control suites are riddled with foreign export controls and licence kill-switches. Our mission-control software is delivered with source-available licences to your sovereign operators, so the program cannot be remotely revoked. It covers tasking, telemetry, command uplink, anomaly resolution, orbit determination and cross-platform fleet management.
5. Operator certification & training
We certify your engineers, analysts and operators on the full lifecycle — from satellite assembly cleanroom procedures through to live mission operations and incident response. Training is hands-on, runs in your country wherever possible, and ends with a documented competency framework that lets you grow the team after we've left.
6. Launch brokering and integration
We are launch-vehicle agnostic. We broker launch slots across SpaceX (Transporter rideshare), ISRO (PSLV/SSLV), Arianespace, Rocket Lab, Firefly, and emerging Indian and UAE providers — chosen for the orbit, the schedule, and the political acceptability to your government. Sovereign programs cannot be hostage to a single launch provider, and our schedule discipline is built around that principle.
7. Lead times and delivery model
Across the 31 application archetypes we have published spec sheets for, lead times to first launch run from 6 to 42 months — deliberately on the agile end. We halve typical prime-contractor timelines by standardising the bus, pre-qualifying the payload integration, and parallelising the ground-segment build with the satellite build. Each spec sheet on our site lists the payload, payload spec, satellite weight and count, orbit, ground stations, mission control, spectrum, analytics team, operations team and lead time for that specific application.
8. Where this has flown before
Our heritage includes ExseedSat 1 (2018, India's first privately built satellite, in orbit), ExseedSat 2 (2019), and the Tonga sovereign communications restoration (2022, after the Hunga Tonga–Hunga Haʻapai eruption severed the kingdom's only undersea cable). The full record is at /experience/.
