FIELD: physics.;SUBSTANCE: invention can be used for ephemeral provisioning of a process for controlling global navigation satellite system (GNSS) spacecraft. A low-orbiting spacecraft fitted with apparatus for synchronising the on-board time scale with the system time scale, apparatus for determining orbit parameters from ground-based radio beacons and consumer navigation equipment is taken to an orbit. During orbit flight thereof, the on-board time scale is synchronised with the system time scale of the GNSS; orbit parameters are determined from radio beacon signals; a GNSS spacecraft navigation message signal is received; Doppler frequency shift of the message signal is measured. Orbit parameters of the low-orbiting spacecraft and the measured values of the Doppler frequency shift of the message signal on-board the low-orbiting spacecraft are used to determine the orbit of navigation GNSS spacecraft and then transmitted for reception thereof at the GNSS spacecraft.;EFFECT: high measurement accuracy.;1 dwg
