The omnidirectional coverage of low-profile TTC antennas onboard minispacecraft

The optimization of antenna placement onboard minisatellites is key in shaping the coverage pattern of TTC (telemetry, teleranging and telecommand) links. A careful selection of phasing between two or more TTC antennas is needed to mitigate the occurrence of nulls and to maintain the directions of the majority of the radio wave propagation towards the Earth-facing side. In the case of a small spacecraft, the MoM offers acceptable computing time and accuracy.
