Abstract:	After GPS use for decades, GLONASS is also widely used nowadays and GPS/GLONASS combination has become the first multi-constellation standard for high-end receivers for precise applications, but also for mass-market chipsets. GNSS have become strategic today, and Europe and China are deploying their own systems respectively named GALILEO and BEIDOU. Full Operation Capacity is announced for 2020 for both constellations. First mass-market chips with a four-constellation capacity are being produced, and the present paper gives early performance results for PVTs using the four systems. After a presentation of theory for combining signals, early PVT experimentation results are given for static receivers but also for dynamic tests in real environment. First PVTs show that in flight GALILEO and BEIDOU satellites can already be used in combination with GPS and GLONASS, with a typical pseudorange accuracy in the order of 1 to 2 meters RMS. 2020 is a challenging date for FOC for the coming constellations, but Early Services should be reached by this date with a reduced number of satellites. Four-constellation PVTs should be even more accurate than GPS/GLONASS ones, in particular in constrained
