Access to Space


Payload Orbital Delivery System (PODS)

PODS is a cost-effective system for sending small satellites to orbit. It carries small spacecraft to orbit attached to large satellites, and then dispenses them as free-flyers near GEO. With an average of 6 satellites launched each year, SSL can help you find a ride to space!

Why Hosted and Dispensed Payloads?

Hosted payloads allow governments, scientific institutions, and organizations the benefit of having their mission payload on board a Geostationary Earth Orbit (GEO) satellite with shorter lead times at lower costs than dedicated missions.

Dispensed Payloads allow affordable access to GTO or GEO for small missions, with shorter lead times than dedicated missions.


SSL Enabled Benefits For Hosted And Dispensed Payloads

Low 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 1-4 year technology demonstrations while the 15+ year bus design life allows mission continuity operations
  • 55+ years of experience with 80+ 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
  • 15+ SSL satellites in backlog with many able to accommodate hosted payloads
  • Hosted payloads can be integrated and launched within the typical commercial GEO satellite timeframe of 22 to 36 months
  • Hosted payloads received for host integration as late as 6 to 12 months prior to launch

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 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 payloads can 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

SSL Enabled Benefits:

  • More science for smaller budgets
  • Affordable Access to Space
  • Frequent / Fast Access to Space
  • Low Risk Solutions
  • Proven Platform Stability
  • Accommodation Flexibility
  • Fixed Cost
  • Heritage and Reliability
  • Data Downlink Options
  • Shared or Dedicated Operations
  • Payload Control Options
