Document Number/Ref.-No. 00-6383A01 (113491 2) Issue 1.0 Page 11 of 26 After typing the above line, on the monitor there should be two windows displayed, one window consisting of 25 lines and one window consisting of 1 line. The window with 25 lines should have some text displayed, this is the window where the command acknowledgments from the LAAS radios and status reported by the LAAS radios is displayed. The 1 line window is where commands for the LAAS Host Simulator are typed.
Document Number/Ref.-No. 00-6383A01 (113491 2) Issue 1.0 Page 12 of 26 The calibration consists of accurately measuring the simulated GPS signal period and determining the error (in microseconds) from one second. The CountsPerSecond entry of the configuration file should then be changed by that number. The default value of CountsPerSecond is 16960, which will provide a nominal 1 PPS simulated GPS signal given an ideal crystal oscillator.
