Hosted and dispensed payloads allow governments, scientific institutions, and organizations the benefit of frequent access to space with shorter lead times at lower costs than dedicated missions. Hosted Payloads have their mission supported by a host Geostationary Earth Orbit (GEO) satellite. Small mission dispensed payloads are deployed from their host to GEO Transfer Orbit (GTO) or near GEO.
SSL-Enabled Benefits for Hosted & Dispensed PayloadsLow Risk Solutions with SSL’s Vast Experience• Successfully hosted 12 dissimilar payloads since 2001 with two in progress covering all payload types
– Scientific, navigation, optic/imaging/IR, and communications
Assured Access to Space and Mission Life with SSL Heritage and High Reliability• Large beginning-of-life margins easily enable 1- to 4- year technology demonstrations while the
15+ year bus design life allows mission continuity operations• 55+ years of experience with 70+ GEO satellites currently operating worldwide
Frequent/Fast Space Access & Sustained Model with SSL’s Frequent Launches• Five to eight launches per year to multiple orbit locations for major satellite operators• Nineteen SSL satellites in backlog with many able to accommodate hosted and dispensed payloads• Payloads can be integrated and launched within the typical commercial GEO satellite timeframe of
22 to 36 months• Payloads received for host integration as late as 6 to 12 months prior to launch• Accurate, controlled, and low-tumble-rate ejection from host for dispensed payloads
Mission Stability Requirements Met with SSL’s Proven Platform• Demonstrated low on-orbit jitter without isolation measures (GOES I – M, MTSAT-1R)• Additional isolation available if needed
Accommodation and Flexibility with Highly Scalable 1300 Bus• SSL’s modular, adaptive bus has inherent flexibility for varying accommodations• Processes, policies, integration and test plans, and risk mitigation strategies in place for both small
and large payloads
Affordable Fixed-Cost Access to Space• Cost reductions over dedicated missions can result from shared integration, launch, and operations
with the host satellite• Hosted and dispensed payloads benefit from the highly competitive Firm Fixed Price contracts
typical of commercial satellites with a fixed accommodation cost
Hosted Payload Operation Options• Ability to lease commercial services already on board the commercial communications
satellite to transmit data back to Earth• Ability to use existing host satellite operations facilities for hosted payload control• Shared command and control of the hosted payload through the host satellite or a completely
dedicated and separate system operated by the hosted payload owner

GEO Orbit Benefits for Hosted Payloads• Unique temporal and spatial resolution• Persistent observations of the same geographic region• Spatial and temporal changes can be distinguished• Ambiguity inherent to observations from Low Earth Orbit (LEO) is eliminated• Near-global coverage can be provided with only three geostationary satellites
(i.e. positioned to view Europe/Middle East/Africa, Asia/Australasia, and the Americas)
How Do Dispensed Payloads Work?• The dispensed payload is integrated with the host spacecraft 6 to 12 months before launch• The host carries the dispensed payload to the desired orbit (typically GTO or near-GEO)• The host spacecraft ejects the dispensed payload with a controlled, low-tumble-rate ejection• The dispensed payload clears the host, powers on, and commences operations
