The local orbital reference system is defined at each point of the orbit by three unit vectors. These vectors are derived from the satellite position and velocity vectors: Vector L is colinear with position vector P (on the axis between the Earth’s centre and the satellite). It defines the yaw axis. Vector T is perpendicular to the orbital plane (vector L, vector V). It defines the pitch axis. Vector R completes the set of orthogonal axes. It lies in the plane defined by Vectors L and V and defines the roll axis. It does not coincide exactly with the velocity vector due to the eccentricity of the orbit.

CONT

Spacecraft axes. The three orthogonal axes of rotation : roll, pitch and yaw. If the spacecraft has a recognisable longitudinal axis or a specified forward direction of flight, the axes are analogous to those of an aircraft, where the roll axis is the longitudinal axis; the pitch axis is in the plane of the wings; and the yaw axis is the "vertical" axis, orthogonal to both the roll and pitch axes. The axes are mutually perpendicular, with an "origin" at the vehicle's centre of mass. For a winged spacecraft such as a Space Shuttle, the similarity with an aircraft is obvious. For expendable launch vehicles the roll axis is the axis which is vertical at launch and the other axes are more-or-less arbitrarily assigned since the vehicle rotates about the roll axis in flight.... The axes of a cylindrical spacecraft(e. g. Apollo, Suyuz, etc.) are similar to those of an ELV [Expendable Launch Vehicle] at launch, but one orbit assume the axis-definition of an aircraft(i. e. defined relative to the pilot's seat). The axes of a satellite mirror those of an aircraft "flying along the orbital arc" : the roll axis is aligned with the direction of travel; the yaw axis passes through the sub-satellite point; and the pitch axis is orthogonal to the other two. For a satellite in an equatorial orbit, the pitch axis is aligned approximately with the Earth's spin axis. The pitch axis is also the spin axis for the spin-stabilised satellite.

OBS

In the compilation of engineering drawings the three orthogonal axes are often labelled in Cartesian fashion: x=roll, y=pitch, z=yaw. For the three-axis stabilised spacecraft, the x-axis and y-axis are otherwise known as the east-west and north-south axes, respectively; the z-axis passes through the sub-satellite point. This leads to the definition of the box-shaped satellite’s faces as follows: the "plus-x face" faces east; the "minus-x face" faces west; +y faces south; -y faces north; +z is the Earth-pointing face; and -z is the "anti-Earth face."

In 1979, Boeing and the US Air Force Rocket Propulsion Laboratory proposed a small unmanned "Air-Launched Sortie Vehicle", ALSV consisting of a reusable spaceplane and a huge expendable propellant tank. The vehicle could overfly any point on Earth within 90 minutes of the launch order and also perform other military missions such as satellite inspection. It then returns to a military airbase and lands horizontally like the Space Shuttle.

A specific increment's planning operation may begin several years before the relevant STS launch(or OMV [Orbital Maneuvering Vehicle] deployment from the manned base). A specific increment's executions operations begin with the Station Program's realtime support to launch of the relevant transportation mission(STS/OMV), and generally extends through the initiation of similar support to the respective follow on transportation mission. ELV [Expendable Launch Vehicle] arrivals at Station elements are contained within the relevant increment. For the manned base, increment duration may vary according to the number of STS visits per year(for eight flights per year, increment duration is 45 days; for five flights per year, 72 days). For platforms, increment duration is related to the period between servicing, between deployment and return to Earth, or between deployment and the end of its operational lifetime.
