Abstract

The Ultra-Fast Flash Observatory (UFFO) aims to detect the earliest moment of Gamma-RayBursts (GRBs) which is not well known, resulting into the enhancement of GRB mechanismunderstanding. The pathfinder mission was proposed to be a scaled-down version of UFFO,and only contains the UFFO Burst Alert & Trigger Telescope (UBAT) measuring theX-ray/gamma-ray with the wide-field of view and the Slewing Mirror Telescope (SMT) with arapid-response for the UV/optical photons. Once the UBAT detects a GRB candidate with theposition accuracy of 10 arcmin, the SMT steers the UV/optical photons from the candidateto the telescope by the fast rotatable mirror and provides the early UV/optical photonsmeasurements with 4 arcsec accuracy. The SMT has a modified Ritchey-Chrètien telescopewith the aperture size of 10 cm diameter including the rotatable mirror and the imagereadout by the intensified charge-coupled device. There is a key board called the UFFOData Acquisition system (UDAQ) that manages the communication of each telescope and alsoof the satellite and the UFFO overall operation. This pathfinder is designed and builtwithin the limited size and weight of  ~20 kg and the low power consumption up to ~30 W. We will discuss the design and performance of the UFFO-pathfinder, and itsintegration to the Lomonosov satellite.
