Hosted Secondary Payload Opportunities Provide Rapid/Low-Cost Access to Space

GEO

Orbital Sciences Corporation’s Hosted Payload Interface (HPI) allows small payloads for science,

technology demonstration, and national security applications to be mounted onto Orbital’s GEOStar-2

bus GEO communications platform. This hosted payload program takes advantage of the high

frequency of commercial satellite launches and the excess resources that typically exist on a

commercial communications satellite to provide frequent and low-cost access to space.

Mission Opportunities

Hosted payloads provide a novel way to serve the needs of the science, technology demonstration,

and security and defense communities as well as the space-based commercial telecommunications

industry. Hosted payloads can be housed on spacecraft whose primary mission does not require full

use of communications payload capacity over the 15-year mission life of the commercial satellite.

The satellite owner/operator works with Orbital and the hosted payload provider to make use of the

available surplus spacecraft resources. By taking advantage of this excess, hosting can be done at a

fraction of the cost of typical science and technology demonstration satellite missions using dedicated

spacecraft.

The frequency of commercial spacecraft launches provides many opportunities for small payloads to

gain access to space. Payload hosting on Orbital’s GEOStar Bus is available on an almost yearly basis

for future launches. This robust launch pace and the quick turnaround and strict schedule requirements

of commercial spacecraft programs (typically 24-27 months) ensure efcient access to space with

minimal risk of delay.

Programs

• Orbital integrated the Geostationary

Communication and Control

Segment onto Intelsat’s Galaxy 15

spacecraft for the Federal Aviation

Administration’s Wide Area

Augmentation System. Galaxy 15

was launched in October 2005 and

continues operation.

• The Commercially Hosted Infrared

Payload Flight Demonstration Program

(CHIRP) is for the Air Force's Third

Generation Infrared Surveillance

(3GIRS) program. The SAIC wide-eld

of view sensor was integrated onto

the Orbital-built SES-2 commercial

GEO communications satellite to

validate missile warning technologies

from geosynchronous orbit in a fast

and cost-effective manner. SES-2 was

successfully launched in September

2011.
