OVERVIEW & SPESIFIKASI
Parallel 24-channel GPS receiver capabilities and compatibility with SBAS (WAAS / EGNOS) and MICHIBIKI
Features
WAAS, EGNOS and MICHIBIKI compatible
SBAS, Satellite Based Augmentation Systems, are fully operated in USA (WAAS) and Europe (EGNOS).
GPS-21 is able to receive the seamless correction signals provided from these systems.
MICHIBIKI (Quasi-Zenith Satellite System) is a Japanese satellite positioning system composed mainly of satellites with quasi – zenith orbit.
Four satellites take non-symmetrical figure-of-moons trajectory up and down, so that one satellite in the country will always be arranged in the zenith direction, complementing GPS positioning. Moreover, positioning accuracy can be improved by receiving sub meter-class reinforcement signals broadcast from the quasi-zenith satellite.
MICHIBIKI can be used in East Asia and Oceania area only.
24-channel reception
Parallel 24-channel receiver provides precise and quick positioning at any time.
