Moves rte_pos and rte_los backwards to the target altitude.

The method gives the rte_pos and rte_los at the target altitude to reach the original rte_pos and rte_los with a geometrical ppath. That is, the movement is backwards in terms of viewing direction.

If the original rte_los is reversed with respect to the line-of-sight direction, then set the GIN los_reversed to 1. One such case is that if rte_los represents surface incidence angles, i.e. holds the zenith and nadir angle towards the sensor.

There is also sensor_pos_losBackwardToAltitude().
