A NEW LAND-BASED AIRCRAFT PRECISION APPROACH BASED ON PPP
Abstract A new landbased aircraft precision approach based on precise point positioning technology was proposed，which can support the blind landing of fixedwing aircraft，helicopters and unmanned aerial vehicles.The approach can reduce the risk of landing in bad weather and greatly simplifies the airport equipment and reduce the cost of construction of the airport.Moreover，a precise ephemeris compression method was presented in the paper，which can meet two hours of precise point positioning using two Beidou short messages.
