b) Orbital height
(Lo): The perpendicular distance between the supraorbital and infraorbital margins of the orbit.
A Walker Constellation consists of three integer parameters: the number of satellites T, the number of orbit planes P, and the phase factor between satellites in adjacent planes F, and two other orbital parameters: the orbital height
h, and the inclination i.
The increased use of lightweight Cube-Sats (100 mm cubes) has brought solar sails to the fore for slow manoeuvring and raising orbital height
However, this value of Leo-SAR is around 9.8% since its orbital height
is low and the effect of perturbation force is obvious.
The orbital height
of the satellite has been modified to 600 km above the earth's surface compared to 690 km, which is the current orbit of DubaiSat-1.
Despite its thousand-mile orbital height
, the 100-foot aluminized balloon rivals 1st-magnitude stars, catching the attention of even casual watchers.
using (14) and taking into account that M [much greater than] m we further obtain (15), where M is the source of the gravitational field = the mass of the Earth in our case [M.sub.e], and R is the radius of the massive body = [R.sub.e], and r = [R.sub.e] + [z.sub.orb] it's orbital height
plus Earth radius for an Earth-based satellite.
The $10million Ansari X Prize was last week award-ed to Scaled Composites for launching Spaceship One, a privately built, reusable, craft to orbital height
twice within a fortnight.
Strictly speaking, this only applies to objects at exactly the same orbital height
as the centre of mass (CM) of the satellite.
The orbital length and height (4.22 [+ or -] 0.009 cm and 3.86 [+ or -] 0.005 cm, respectively) was more in left than right orbit (4.04 [+ or -] 0.007 cm and 3.81 [+ or -] 0.004 cm, respectively), which was disagreement with the finding of Sarma where orbital length was more in left orbit, while the right orbit showed more orbital height
. Similarly, orbital depth and circumference were recorded more in the right orbit (4.66 [+ or -] 0.004 and 13.49 [+ or -] 0.009 cm, respectively) than the left one (4.61 [+ or -] 0.003 and 13.09 [+ or -] 0.01 cm, respectively) in blackbuck.
Dnepr's launch of the UAE satellite is expected to give it better orbital height
and inclination in space.
