Precise GRB source locations from the renewed interplanetary network

A new interplanetary network (IPN) is made possible by the modication of the NEAR mission, now at 2 AU distance. With Ulysses and the near-Earth GRB monitors, this fully long-baseline network will produce GRB localizations at a rate of about one per week, with ac- curacies varying from several to tens of arc minutes. Given the delays inherent in the collection of deep space data, high-precision alerts with delays under one day should be possible at a rate of one to several per month. An auto- matic analysis system is being developed to optimize the process.
