| Keywords: text surreal writing 330-PSA-286-60 (USN 710829): New Navigational Satellite. The Transit ground stations receive the Doppler data from satellite at T1. The data are corrected for the effect of ionospheric refraction and sent to a Computing Center which then calculates new orbital parameters for the satellite for several days in advance. This information is transmitted to an Injection Station, and twice a day as the satellite passes within range at T2, the Injection Station transmits to the satellite these new orbital parameters and a time correction. From then on, the satellite transmits once each minute the data received from the Injection Station (it transmits the other satellite signals continuously), When the satellite at T3 is within range of a ship with special receiving equipment, the navigator can by a simple pushbutton operation obtain the most accurate navigational fix ever before possible.
