Hosted Payloads

What is a Hosted Payload?

The term Hosted Payload refers to the utilization of available power, mass and space on commercial satellites to accommodate additional transponders, instruments or other space-bound items.

By offering hosted payload opportunities on board SES spacecraft, the U.S. Government is provided with consistent, dependable and affordable access to space.

Missions Suited for Hosted Payloads:

Risk Reduction Activities
Technology Advancement
Flight Qualification
Operational Missions:
- Space Situational Awareness
- Tailored Communication Systems
- Space Environmental Monitoring
- Space Based Augmentation for Navigation
- Earth Monitoring

For other U.S. Government mission requirements, SES can apply its fleet and mission development skills to build, launch and operate dedicated spacecraft.

Timely and Affordable Access to Space

At a time where many government satellite programs have experienced schedule delays, cancellations and budgetary challenges, the use of commercially hosted payloads can help to maintain (or in some cases accelerate) program schedules, fill gaps in operational and proof-of-concept activities and provide a timely and affordable means of accessing space.

The frequency of commercially hosted payloads provides many opportunities for government payloads to reach orbit. SES currently has 11 spacecraft in various stages of development over the next three to four years, many of which are hosted payload opportunities. The robust launch pace and the strict schedule requirements of commercial spacecraft programs ensures efficient access to space with minimal chance for delays.

In recent years, commercially hosted payloads have received increased attention and interest from the U.S. Government as a means of accessing space. In particular, the U.S. Air Force has been on the leading edge of exploring opportunities with commercial satellite operators and embarked on an innovative approach with its Commercially Hosted Infrared Payload (CHIRP) flight demonstration program.

Industry Leader: Three Government Payloads on Contract

Commercially Hosted Infrared Payload (CHIRP) Flight Demonstration Program

SES GS will host an experimental U.S. Air Force sensor on an SES satellite operating over the United States. The CHIRP flight demonstration program will test a new type of infrared sensor from geosynchronous orbit. This sensor will be integrated onto a commercial satellite and the data it receives will be transmitted to a ground station for analysis. CHIRP launched on September 21, 2011. Watch the launch here. You can also follow CHIRP’s progress on Twitter.

This flight demonstration program illustrates how a commercial satellite operator can provide tremendous value to government customers looking for affordable access to space. SES GS will also provide the services to determine the utility of the sensor in terms of data, performance validation and interoperability.

News on the CHIRP Program:

European Geostationary Navigation Overlay Service (EGNOS)

The European Geostationary Navigation Overlay Service (EGNOS) provides European navigation services, supplementing the American GPS and the Russian-led GLONASS navigation systems. It verifies, improves and reports on the reliability and accuracy of positioning signals in the European states area. In the future, it will also support the European GALILEO navigation system.

ASTRA has been awarded two contracts for EGNOS following two completely separate tenders by the European Commission, which manages the program on behalf of the European Union. Two tailor-made payloads and the related ground infrastructure, including fully redundant ground network hosting and two redundantuplink chains, will be supplied by ASTRA. These are the first fully commercial payloads for the EGNOS program. The hosting satellites provide the capability to extend the coverage of the service from Europe to Africa and other neighboring countries of the EU.

The first EGNOS payload hosted by ASTRA will operate in L-band and be located on the SES-5/Sirius 5 satellite, which will launch in the second half of 2011 to 5 degrees East. ASTRA will start operations of the payload by the end of the same year. The second payload will also operate in L-band and be hosted on the ASTRA 5B satellite. The satellite is scheduled for launch in 2013 and will be positioned at 31.5 degrees East.
