Provided is a method for producing a plug for use in a piercing-rolling mill for producing a seamless steel tube/pipe, and the method for producing the plug for piercing-rolling comprises shotblasting a surface of the plug, and arc-spraying a spray wire so as to form a film on a surface of a base metal of the plug that is shotblasted. In the arc-spraying step, the arc spraying is carried out by using, as the spray wire, a cored wire whose iron sheath tube is charged with at least iron oxide particles among iron particles and the iron oxide particles (one or more of FeO particles, FeOparticles, and FeOparticles), so as to form the film containing iron oxide and Fe. Accordingly, it is possible to enhance the production efficiency of the plug, and to produce the plug for piercing-rolling capable of securing the steady enhancement of the durability life of the plug during the piercing-rolling.

A length of time required for the verification of data transmitted from a satellite or satellites is reduced. A distance r1 calculated from a time delay required for the propagation of a radio wave between a transmitting and a receiving site is obtained, as is a line-of-sight distance r2 which is calculated from the positions of a satellite and a point of reception. When a difference between these two distances is small, data from these satellites are regarded as valid data. However, when the difference is large, data is regarded as involving a large error. The position of the point of reception is determined by a positioning calculation which utilizes data from predetermined three or four verified satellites, or is entered by an operator. The position of the satellite is obtained from orbital data which is delivered by that satellite.

The receiving circuit is very much simplified and particularly, the Costas Loop demodulating circuit detects the phase lock condition when the signal obtained by multiplying the signal of which phase is shifted by 90.degree. and the reversely spread signal is within the preset range without using a phase shifter or other multiplying circuit. Accordingly the circuit structure of the receiver as a whole can be simplified.
