Abstract
The possibility of the USSR's global satellite navigation system GLONASS and the NAVSTAR Global Positioning System using a common navigation system can only be determined following exhaustive testing of two systems in a variety of satellite and receiver modes and configurations. The authors describe their first attempts to carry out basic position-fixing and timing measurements with a single-channel, sequencing digital receiver in a C/A code phase-measurement mode using the GLONASS satellites. The receiver used to produce the fixes was a digital sequencing unit with a single stage of downconversion and followed by 1-bit quantization. Code acquisition was accomplished using 1-Q channels measuring code phase. The number of satellites available in the present preoperational phase heavily restricts the time and satellite configurations which can be tested. However, the results have encouraged the authors to propose a range of experiments aimed at evaluating the two systems and eventual integration.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
