- On-board computer and data-handling
- Power management
- Software and simulations
- Local existing suppliers for items such as spacecraft harness, MLI, structure etc. clustering for supply chain efficiencies
- In-sourcing of equipmentsand components including solar-array production, propulsion, TT&C and other major elements
- A complete industrial complex for smallsatplatform production >
Industrialisation is driven by volume purchasing power
ISN LEO industrialisation
The FPSS platform is designed to enable various payloads to be embarked, with the first spacecraft constellations specifically tailored to the governmental services market
- Communications payloads for secure and reliable global communications capabilities
- GNSS enhancement payloads to give an affordable national navigation and timing system
- Earth Observation payloads in optical, radar and thermal bands including our unique ability to deliver real-time optical imagery to the ground user without the latency of a ground station
In-orbit demonstration programs for each of the above systems can be produced to show the capabilities prior to full constellation manufacture
Global secure communications
Dedicated global constellation for secure government communications
- Using government allocated frequencies –including X-band
- Global persistent coverage
- On-board transmission systems close the link to ground handheld
- On-board security systems including anti-jamming frequency hopping, high level crypto
- Robust constellation less vulnerable than single geo-satellite
A global secure communications capability at an affordable cost
Low-Earth Orbit Navigation Augmentation
A global augmentation solution for navigation, positioning and timing
- SBAS (Satellite-Based Augmentation of Signals) using LEO rather than GEO satellite systems
- Increased accuracy for civil and government applications
- SBAS retransmission of L-band signals means no additional on-board clocks
- Signal augmentation using worldwide verified positioning sites
- Timing propagation accuracy verified across the constellation using ISL linking and local correction
SBAS LEO capability can be utilisedby many countries which do not have access or funding for national or regional SBAS Geo-stationary satellite systems
Persistent EO Application Direct to Mobile Users
Security and government specialists need access to real-time information –currently only available to major countries
- EO instrumentation for monitoring and surveillance
- On-board processing and rectification removes need for ground station processing and delay
- On-board transmission systems close the link to ground handheld
- Saturn Patent for direct Mobile EO transmission to mobile user terminals
- Tasking system and intelligent on-board mission planning allows individual users to request satellite overwatch at a specific location
Store-and-forward capability for mass surveillance also available with large memory capacity
EO Payload Description
EO payload design uses latest technologies to achieve very high resolutionimaging
