Communication satellites
Resilient satellite communications
What it is
Communication satellites provide assured, wide-area connectivity for command, control and civil continuity: links that keep working where terrestrial networks cannot reach and when they are attacked, under the owner's control.
How it is employed
Satellite communications carry the links that must not fail: strategic command and control, deployed-force reachback, and continuity for government and critical services when ground networks are cut. Resilience is designed in. The question is who holds the keys and the priority plan.
Why it matters now
Undersea cables and terrestrial backbones across the region have proven vulnerable to accident and attack, and leased capacity on foreign systems carries access conditions that surface exactly in crisis. Assured national capacity is the difference between degraded and disconnected.
Procurement & integration
Options run from assured capacity arrangements to dedicated payloads and sovereign platforms with national ground control. Unstrat structures the engagement so control over keys, priority and coverage sits with the buyer, and pairs space and ground segments through one channel.
Capability
- LEO smallsat constellations at 400–600 km: round-trip latency under 30 ms, revisit measured in minutes, latency parity with terrestrial fibre
- End-to-end encryption under national key management, so no foreign operator holds decryption authority for government or military traffic
- Spectrum sovereignty: ITU frequency filings held by the nation, secured before commercial operators pre-empt the 6G non-terrestrial slots
- Direct-to-device connectivity to standard smartphones per 3GPP Release 17/18 non-terrestrial network standards
- Resilience by design: national ground stations and inter-satellite cross-links that survive the loss of any single point
- Quantum key distribution payloads available as a hosted addition on the same constellation
The Unstrat difference
01Independent, non-aligned origin, with no political exposure to any major-power ecosystem.
02One accountable team from first briefing through delivery and in-region sustainment.
03You hold the encryption keys, the ground stations, the traffic logs and the kill-switch.
Sourcing routes compared
| Consideration | Major-power prime | Independent principal via Unstrat |
|---|---|---|
| Access in crisis | Leased capacity subject to the owner's conditions when it matters most | Assured capacity under the buyer's control and priority plan |
| Political conditions | Disclosure rules, re-export restrictions and upgrade approvals held by a foreign government | Independent, non-aligned origin, accountable to the buyer's flag |
| Accountability | Multiple contractors and a foreign prime's release schedule | One accountable team from first briefing through delivery and in-region sustainment |
| Sustainment | Support tied to the supplier's home market and political relationship | Sustainment, spares and training delivered in-region for the life of the system |
Comparison is qualitative. Detailed specifications are shared under briefing once the export-control position for your market is confirmed.

Communication satellites: questions
What are Communication satellites?
Communication satellites are Unstrat's Space (Space Domain) capability: Sovereign satellite communications from a firm that has built and launched satellites and ground stations: LEO smallsat constellations at 400–600 km with sub-30 ms latency, encryption under national key management and spectrum filings held by the nation, not a foreign operator that can throttle, surveil or switch you off.
How do Communication satellites work?
Communication satellites deliver their effect through LEO smallsat constellations at 400–600 km: round-trip latency under 30 ms, revisit measured in minutes, latency parity with terrestrial fibre, End-to-end encryption under national key management, so no foreign operator holds decryption authority for government or military traffic and Spectrum sovereignty: ITU frequency filings held by the nation, secured before commercial operators pre-empt the 6G non-terrestrial slots, capabilities matched to the requirement and confirmed under briefing rather than published.
Who makes Communication satellites?
Communication satellites are built by The Satellite Programme Partner, whose focus is satellites & sovereign space programmes. Unstrat represents The Satellite Programme Partner to government and enterprise buyers worldwide as an independent, non-aligned prime vendor.
Who uses Communication satellites?
Government and enterprise buyers acquire Communication satellites to address contested & denied communications across the space domain, matched to the mission and accountable to them, not to a foreign vendor's government.
Why choose Communication satellites over a major-power alternative?
Communication satellites are sourced from an independent, non-aligned manufacturer, so they carry no major-power disclosure rules, upgrade-locks or political ramifications. Concretely: you hold the encryption keys, the ground stations, the traffic logs and the kill-switch. The capability is accountable to you, not to a foreign vendor's government and its release schedule.
How are Communication satellites procured, and where can it be exported?
Assured connectivity you control, free of coalition access conditions. Every engagement begins with a briefing, and export eligibility is confirmed per market under briefing rather than published. Where controlled capabilities are involved, the classification and end-user-certificate chain is confirmed first. Communication satellites are then sustained in-region by one accountable team from briefing through long-term operation.
Questions buyers ask
What are communication satellites used for in defence?
Communication satellites carry the links that must not fail: strategic command and control, deployed-force reachback, and continuity for government and critical services when ground networks are cut. Resilience is designed in. The question that decides sovereignty is who holds the keys and the priority plan.
See: Communication satellites capabilityCommunication satellites in the catalogue
Why hold national satellite communications instead of leasing capacity?
Leased capacity on foreign systems carries access conditions that surface exactly in crisis, and undersea cables and terrestrial backbones have proven vulnerable to accident and attack. Assured national capacity is the difference between degraded and disconnected. We structure the engagement so control over keys, priority and coverage sits with the buyer.
What does sovereign satellite communications actually mean?
It means encryption under national key management, spectrum filings held by the nation, and priority decided by the buyer rather than a foreign operator. Our published product describes LEO smallsat capacity with these controls held nationally. The test is simple: can a foreign operator throttle, read or switch off government traffic.
See: Communication satellites capabilityGEO against LEO satellites
Satellite communications that keep working when ground networks are cut
That is the mission satellite communications exist for: continuity for command, deployed forces and government when terrestrial networks are attacked or severed. Resilience is designed into the constellation and the priority plan. We pair space and ground segments through one channel so the resilience is not undone by a rented ground station.
See: Communication satellites capabilityGround stations capability
How do satellite communications fit with tactical radios on the ground?
Satellite links carry the strategic reachback while software-defined radios carry the tactical picture, and both matter more when the spectrum is contested. Capability that lives in software can adapt in the field, and satellite capacity under national key management keeps the backbone under control. We represent both layers so crypto custody sits with the buyer across the whole chain.

Communication satellites for government continuity during a disaster
When a cable is severed or a terrestrial network fails, assured satellite capacity is what keeps government and critical services connected. The same capability underpins rapid restoration of connectivity after disruption. We represent a rapid-restoration model built on pre-staged hardware and rehearsed deployment.

GEO or LEO for a national communications constellation
LEO smallsats sit closer and cut latency; GEO holds a fixed slot with wide coverage from one platform. Our published communications product describes a LEO smallsat approach with sub-30 ms latency and national key management. The choice is set by the mission mix, and our comparison page lays out the trade neutrally rather than pushing one orbit.
See: GEO against LEO satellitesCommunication satellites in the catalogue
Communication satellites paired with a national ground segment from the start
Assured capacity in orbit is undone if control runs through a rented foreign ground station, so the ground segment is part of the same decision. A national ground segment keeps tasking, keys and priority domestic. We pair the space and ground segments through one channel rather than leaving the buyer to integrate them afterwards.
See: Ground stations capabilityCommunication satellites capability
We have a political commitment to sovereign communications but no engineering department. What does a programme need to include?
It needs the space segment, a national ground segment, and the people trained to run both, structured for ownership from the start rather than bolted on afterwards. Space capability assembled as separate purchases decays; structured as a programme it compounds. We represent the full chain through one accountable channel and build the operator pipeline alongside the hardware.
See: Sovereign space infrastructure capabilitySpace program training capability
If our government traffic is carried by a foreign operator, what leverage does that give them in a crisis?
Leased capacity is subject to the owner's conditions exactly when it matters most, and those conditions surface in crisis rather than in peacetime. The independent route we represent holds encryption keys and spectrum filings nationally, so the operator cannot throttle, read or switch off the traffic. We do not publish claims about any specific foreign operator's behaviour, only the control model we offer.
See: How the routes compareCommunication satellites capability
How does building a national communications constellation compare with the major-power procurement route on political conditions?
The major-power route ties support to the supplier's home market and political relationship, with upgrade approvals held abroad. The independent route we represent is non-aligned in origin, accountable to the buyer's flag, with sustainment and training delivered in-region for the life of the system. Our comparison page sets the considerations out side by side without fabricated figures.
What does a sovereign communications programme cost, and can you give a figure before we define scope?
We do not publish price bands, because any figure quoted without a defined scope is guesswork. Cost is shaped by constellation size, coverage, ground segment and the training load, and we scope it against the buyer's mission mix. What we can commit to is a structure where control over keys, priority and coverage stays with the buyer.

How do we keep the resilience of a constellation from being undone by the ground segment?
A resilient space segment loses its value if tasking and control run through a rented foreign ground station. Ground stations are the terrestrial backbone, and a national ground segment keeps custody and priority domestic. We pair the space and ground segments through one channel so the resilience is designed across both, not just in orbit.
See: Ground stations capabilitySovereign ground segment against a data service
Can a communications programme also carry civil connectivity, or is it defence only?
It can carry both. Assured national capacity underpins government continuity and can extend to civil connectivity and disaster restoration, which makes the investment easier to justify across ministries. We represent civil space applications and a rapid-restoration model alongside the defence capability.
See: Civil space applications in the catalogueRapid capability restoration in the catalogue
How do satellite communications and software-defined radios fit into one secure communications programme?
Satellite capacity carries the strategic reachback while software-defined radios carry the tactical links, and both need crypto custody held nationally to be sovereign. We represent both layers so encryption and upgrade approval sit with the buyer across the whole chain rather than split between a foreign satellite operator and a foreign radio prime. The two are scoped together as one secure communications programme.
