Available orbital constellations for dual-satellite reception. Available orbital constellations of two satellites from SDARS measurements (coloured diamonds) and from GNSS measurements (coloured fields) quantised to seven azimuth separation sections, nine elevation ranges and five environments. The colour indicates the measurement length. The GNSS data is further used for dual-satellite state analysis. A dual-satellite state analysis from SDARS is omitted, since conclusions for dual-satellite reception in dependency to azimuth angle separation or elevation are rather limited.
