pub fn comm_timeline_linear(
departure: Planet,
arrival: Planet,
departure_jd: f64,
travel_time_s: f64,
n_steps: usize,
) -> Vec<CommTimelineEntry>Expand description
Compute communication timeline along a linear route between two planets.
Assumes the ship travels in a straight line from departure planet position to arrival planet position (simplified; actual trajectories curve). This is sufficient for estimating the light delay profile.
Returns entries at regular time intervals.
