The experiments selected to be part of the UOSAT 2 payload had several objectives which included the following: to provide the educational community with an operational scientific satellite which could be utilized with a minimal ground station; to provide the scientific community with a new source of data to aid in the understanding of the electro-magnetic properties of the near earth environment; and to provide the amateur radio community with a full complement of instruments for the study and monitoring of radio propagation conditions from high frequency to microwave. In order to meet these objectives the following instruments comprised the UOSAT 2 payload; a triaxial fluxgate magnetometer with a resolution of plus or minus 2 nT and maximum vector sample rate of 6.25 per s; two charged particle counters with threshold energies of 20 and 60 keV; four phase-referenced high-frequency beacons at 7, 14, 21, and 28 MHz; two microwave beacons at 2.4 and 10.47 GHz; and a CCD earth-imaging camera with 2 km resolution, and spectral response of 0.4 -1.0 micrometers. One VHF and one UHF telemetry channel provided data in standard FSK ASCII at a variety of baud rates, as well as Morse code and synthesized voice formats. Though the descriptions are the same, there were some differences between UOSAT 2 and UOSAT experiments.
