Simulated radio sources and their corresponding BELLA detection at (a) ±10°, (b) ±40°, (c) ±90°, and (d) ±170° of Ahead-Behind separation with respect to Wind. Orange dots are the true location of the sources, and stars and ellipses are their corresponding detection and uncertainties, respectively. At each spacecraft configuration, simulations were performed twice with different cadences: 30 s (blue) and 60 s (red). The background maps were generated at a 60-s cadence and show a general overview of the multilateration uncertainty. Uncertainty of the measurements is dominated by the cadence of the instruments and the location of the spacecraft. The best performance of the multilateration technique occurs when the separation angles between all spacecraft are maximised and widely distributed.
