Preliminary analysis for the navigation of multiple-satellite-aided capture sequences at Jupiter

Robust Space Trajectory Design using Belief Stochastic Optimal Control

“…Then, as in Figure 4(b), the belief state is propagated and updated during OD arcs until X T RG−E18 at the time of targeting, close to the trajectory apocenter, when the deterministic ∆v T RG−E18 is applied to the belief state to target the next Europa flyby E18. The deterministic impulse is combined with a linear analytical controller δ∆v (j) T RG−E18 to correct for the state dispersions and target the desired B-plane conditions (B vector and Linearised Time-of-Flight) [30] at E18, with a different velocity correction applied to different belief components X (j)…”

Optimal SEP Trajectories from Earth to Jupiter with Triple Flyby Capture

“…While single gravity-assist trajectories are most commonly proposed [5], double gravity-assists have been proposed for some mission designs [6]. Further, the use of three of the Galilean moons for a triple-satellite-aided capture has been explored by Lynam et al as a means to further reduce the overall ΔV requirements of Jupiter insertion [7][8]. This sequence begins with a hyperbolic arrival trajectory (from a low-thrust Earth-Jupiter trajectory) a few days before the triple-flyby gravity-assist sequence.…”

Impulsive Trajectories from Earth to Callisto-Io-Ganymede Triple Flyby Capture at Jupiter

“…The use of gravity assists of planetary moons to reduce the ΔV required to capture into planetary orbit is called "satellite-aided capture". While most papers discussing satellite-aided capture have focused on using only one satellite gravity assist to aid in the capture [13][14][15][16][17][18], several have proposed using two [19][20][21][22][23] or three [21][22][23][24][25][26] of Jupiter's Galilean moons to capture a spacecraft into orbit about Jupiter. Using three gravity-assists of Jupiter's Galilean moons is called "triple-satellite-aided capture".…”
