Abstract : The paper reports on the operation and results of the double-probe DC electric field experiment on the low altitude polar orbiting Injun 5 satellite. At middle and low latitudes, where the convection electric field is generally very small, the operation of the double-probe electric field antenna is investigated by comparing measured electric fields with the vector V sub s cross the vector B electric field generated by the satellite motion through the ionosphere. Errors caused by sunlight shadows on the probes, wake effects, and antenna impedance variations are discussed. (Author)
