Sensor view angle for an overlap ratio of 1 at equator - DEPRECATED
[view_angle] = CL_gm_equatorialSwath(alt, inc, [er, rotr_pla])
This function is deprecated.
Replacement function: CL_op_equatorialSwath
Computes the view angle as seen from the satellite (angle from the descending vertical) so that the overlap ratio at equator is 1.
The overlap ratio is the ratio Q=Leq/Ded where:
- Leq: portion of the equator seen by the sensor during the time it crosses the equator.
- Deq: gap between 2 consecutive ground tracks at equator.
Notes:
- The planet is assumed spherical, and the orbit circular.
- The sensor is conic and oriented towards the descending vertical.
- The gap between 2 consecutive ground tracks is computed taking the effect of J2 into account.
- The result is undefined (%nan) if inclination is 0 or pi.
Satellite's altitude. [m] (1xN)
