The invention relates to a Beidou-2 positioning, timing and time service terminal, which comprises a main antenna, an auxiliary antenna, a cable and a charger, and is characterized in that the main antenna is used for supporting signal capturing, tracking and joint positioning for five frequency points of a BD2 (Beidou-2) system, a GPS (Global Positioning System) and a GLONASS (Global Navigation Satellite System) and supporting functions of RDSS short message communication and active positioning of the BD2 system; the auxiliary antenna is used for supporting signal capturing, tracking and joint positioning for five frequency points of the BD2 system, the GPS and the GLONASS; the cable comprises a power supply cable and a data cable, the power supply cable mainly completes power supply of the main antenna for the auxiliary antenna, the data cable realizes wired-mode orientation through observed quantity data mutual transmission of the main antenna and the auxiliary antenna; and the charger completes offline charging for a battery of the main antenna and a battery of the auxiliary antenna. The main antenna and the auxiliary antenna of the Beidou-2 positioning, timing and time service terminal adopt an integrated design, functions of a data transmission station are integrated in the main antenna and the auxiliary antenna, and that is, the equipment can independently complete a pseudo-range differential positioning and realize a wireless orientation function between dual antennas at the same time.
