Orbital LEOStar-2 Bus Instrukcja Użytkownika Pobierz pdf

There are eight LEOStar-2 spacecraft

delivered to customers with three

currently in design and production.

LEOStar-2 "Firsts"

• The Dawn planetary spacecraft is

the rst operational application of

electric Ion propulsion, the rst to orbit

a body in the asteroid belt, and the

rst to rendezvous with and orbit two

planetary bodies.

• The GALEX satellite performed the

rst ultraviolet all-sky survey covering

approximately 1 million galaxies.

• The NuSTAR satellite's X-ray

instrument produces images 100

times the sensitivity and 10 times

the resolution of previous X-ray

observatories.

Satellite Bus

LEOStar

™

-2 Bus

An affordable, versatile, small-to-medium size spacecraft bus suitable for SMEX, MIDEX, ESSP, and

Discovery class missions. Compatible with launch vehicles such as Pegasus

, Minotaur, and Delta.

FACTS AT A GLANCE

Orbital’s LEOStar-2 series of spacecraft have supported multiple missions for commercial and

government customers over the past ten years. The current LEOStar-2 product line has an enviable

on-orbit performance record with four on-orbit and three more in production.

Design

Originally designed for the Pegasus XL launch vehicle, Orbital’s LEOStar-2 spacecraft bus provides a

exible, high performance platform for space and earth scientic, remote sensing, and other commercial

applications on a variety of launch vehicles (Pegasus, Minotaur and Delta). The avionics architecture has

been congured for both single-string and redundant applications, supporting missions with durations

up to ten years. LEOStar-2 can accommodate various instrument interfaces, deliver up to 2 kW orbit

average payload power, and support payloads up to 500 kg. Performance options include redundancy,

propulsion capability, high data rate communications, and high-agility/high-accuracy pointing.

Payload Accomodations

The exible LEOStar-2 spacecraft bus has been adapted to a variety of space science, remote sensing,

and technology validation missions. The spacecraft employs a compact avionics suite housed within a

hexagonal bus platform, enabling Orbital to deliver a signicant launch vehicle fairing volume for multiple

instruments. Our modular approach to the spacecraft platform and instrument deck enables parallel

integration and testing, reducing overall delivery schedule. With the LEOStar-2, Orbital has regularly

delivered attitude control better than 15 arc-seconds, with attitude knowledge less than 6 arc-seconds.

Through the inclusion of higher performance actuators, we can achieve greatly improved agility.
