"Japan Aerospace Exploration Agency (JAXA) is planning to conduct precise point positioning (PPP) experiment by using the LEX (L-band experiment) signal channel of QZSS (quasi-zenith satellite system). The target accuracy of the PPP is under 10 cm RMS. The area of the service is all over the Asia and Oceanian region including the Pacific Ocean side where users can receive broadcasting signals by the QZSS satellites. The expected GNSS for the augmentation are GPS, GLONASS, QZSS and Galileo. PPP can provide precise positioning service to many users in the broad regions without dependency of ground stations. A lot of applications like precise farming, Tsunami detection, crustal deformation monitoring and GNSS meteorology are much expected by such the PPP technique. To generate the augmentation information for the PPP service, precise orbit and clock determination of GNSS satellites is necessarily required as well as the ground GNSS reference station network. For these purposes, JAXA decided to newly develop a precise orbit and clock determination software for multiple constellation GNSS from scratch in addition to extending the multi-GNSS monitoring network (MGM-net). We call the software MADOCA (multi-GNSS demonstration tool for orbit and clock analysis). In this paper, we provide the introduction of MADOCA including models and algorithms, technical features, implementation aspects, accuracy evaluation and the future plan."
