Five satellites in orbit. Programs on four continents.
Satellize does not do hardware on paper. What follows is the operational record — eight years, built one mission at a time. Each entry below links to its own page with the full record, the imagery and the verified third-party reading.
What has Satellize actually built and flown?
ExseedSat 1 (2018) — India's first privately built satellite
Launched on SpaceX's SSO-A mission in December 2018, ExseedSat 1 was the first satellite designed and built by a private Indian company to reach orbit. It carried an amateur-radio transponder enabling free voice and data communications across the Indian Ocean region during emergencies — a capability previously dependent on foreign-operated networks. The platform validated our 1U–6U avionics core and our software-defined-radio payload approach. It remains in orbit and tracked by the global amateur-radio community.
ExseedSat 2 (2019) — second-generation comms platform
A follow-on mission with extended communications coverage, hardened avionics and refined ground-segment integration. ExseedSat 2 proved the production line — bus #2 was built faster, cheaper and with measurably fewer integration issues than #1, the curve every sovereign program needs to climb.
Tonga sovereign communications restoration (2022)
On 15 January 2022, the Hunga Tonga–Hunga Haʻapai underwater volcano erupted, severing the kingdom's only undersea cable and cutting Tonga off from the global internet. Satellize was part of the multi-party restoration effort that brought sovereign satellite communications back to the kingdom — a live demonstration that satellite redundancy is not a luxury but a national-security minimum for cable-dependent island and coastal states.
What programs are live now?
- Exseed Sat 1 — India's first private satellite — A 1U cubesat, built from scratch in four months, that extended ordinary amateur-radio handhelds across hundreds of kilometres — and proved a private Indian company could put a working spacecraft into a 600 km polar orbit.
- Exseed Sat 2 / AISAT — The first private satellite from Indian soil — An APRS digipeater for AMSAT India — and the first commercial use of ISRO's revolutionary PS4 fourth-stage platform. Designed and integrated end to end in six working days.
- GSAT-31 — India's 40th communications satellite — A high-throughput Ku-band geostationary spacecraft replacing INSAT-4CR — VSAT, DTH and broadcasting backbone for the Indian subcontinent.
- GSAT-30 — Backbone for a continent — A 3,357 kg C and Ku-band geostationary spacecraft replacing INSAT-4A — the workhorse of Indian VSAT, DTH and broadcasting infrastructure for a generation.
- EOS-04 / RISAT-1A — All-weather, day and night — A 1,710 kg C-band synthetic-aperture-radar spacecraft for agriculture, forestry, hydrology and disaster management — imaging through the cloud cover that defeats optical systems for half the year.
- SpaceShare — Ten missions, one chassis — A joint Satellize–ISRO platform that lets Indian universities, colleges and NGOs fly experimental missions on the PSLV's fourth stage — power and communications shared, payload focus liberated.
- Tonga agriculture estimation. — Every plot, every season — A satellite-led crop estimation programme for the Kingdom of Tonga — multi-spectral and hyperspectral monitoring of root crops, vanilla and coconut across Tongatapu, Vava\u02BBu and Ha\u02BBapai, processed inside the kingdom and delivered to the Ministry of Agriculture, Food, Forests and Fisheries.
- Tonga. — When the cables broke — On 15 January 2022 the Hunga Tonga–Hunga Ha\u02BBapai eruption severed the kingdom's sole undersea fibre, knocking 105,000 people off the global network. Within hours, Satellize provided the sovereign overhead picture — and the backbone link that kept Nuku\u02BBalofa connected to the rest of the wor
- Monsoon early warning. — Minutes, not days — A dedicated micro-constellation for monsoon and cyclone-genesis tracking across the Bay of Bengal, processed in-country and shared with civil defence within minutes of overpass.
Each program reflects the same delivery pattern: sovereign tasking, sovereign processing, sovereign decisions. We integrate, we operate alongside the in-country team during a co-pilot phase, and we hand over.
What pattern repeats across our programs?
Three things, every time:
- Local crew first. Every program ends with a certified in-country team running the satellites. Our success metric is not invoices billed; it is the day we are no longer needed.
- Modular hardware, modular timeline. We do not redesign the bus for every customer. The platform improvements made for one program flow into the next, which is why our second satellite for any given customer is always faster and cheaper than the first.
- Sovereign-friendly supply chain. Every component traces to a supplier and a jurisdiction the customer is comfortable with. No surprise ITAR clauses. No black-box firmware that could be revoked.
How does this compare with traditional primes?
Across our 31 published application archetypes, our lead times to first launch run from 6 to 42 months, against typical prime-contractor timelines of 24–84 months for comparable missions. We achieve this by standardising the bus, pre-qualifying payload integrations, and parallelising the ground segment with the satellite build.
