The figure on the left is an HST observation of GRB970228; on the right, the logo of the 3rd Interplanetary Network.
IPN3 began operations in 1990, with the launch of the Ulysses spacecraft, which carried the GRB experiment. Today, the main spacecraft contributing their data are WIND, 2001 Mars Odyssey, INTEGRAL, Swift, Fermi, and BepiColombo. When the duty cycles and effective fields of view of all the missions in the network are considered, the IPN is a full-time, isotropic all-sky GRB monitor. The flux and fluence efficiencies of the IPN are plotted here. So far, 32 spacecraft have participated in the network.
