Receiver of a system of global satellite navigation code correlators prn blank.

摘要

A GNSS receiver includes a subsystem REDUCING THE NEGATIVE EFFECTS OF MULTIPLE VIAS SIGNALS ON TIMELY AND CORRELATION MEASUREMENTS PRIMERAS least the last, making CORRELATION MEASUREMENTS WITH THE USE OF A BLOCKED PRN code. PRN CODE LOCKED consists of all zeroes, EXCEPT IN BRIEF ADJACENT IMPULSE, LIGHT AND THAT OCCUR IN EACH TRANSITION bit code in a PRN code generated locally. USING THE CODE PRN - LOCKED, the receiver performs MEASUREMENTS OTHER THAN ZERO CORRELATION Only about TRANSITIONS code bits in the code PRN LOCAL. If code PRN PRN CODE LOCAL AND SATELLITE SIGNAL GNSS RECEIVED ARE CLOSELY ALIGNED, DIFFERENT MEASUREMENTS ARE MADE ZERO CORRELATION IN MOMENTS OF TRANSITIONS IN BITS received PRN code. CONTRIBUTIONS TO THE MEASUREMENTS OF CORRELATION SIGNALS VIAS MULTIPLES NOT HAVE TRANSITIONS Debits DURING THE ADJACENT IMPULSE, LIGHT AND SHADE IN THE CODE PRN - LOCKED CANCELED when accumulated MEASUREMENTS OF CORRELATION, because these signals ROADS MULTIPLES They are constant during times of pulses. GNSS RECEIVER (SYSTEM GLOBAL SATELLITE NAVIGATION) includes a PRN code logic - LOCKED CODE PRODUCES THE QUOTED FROM LOCALLY GENERATED PRN code. PRN code logic BLOCKED This results in a code having a value of zero except those adjacent pulses. Alternatively, the PRN code logic - LOCKED PRODUCES LOTS OF VALUE CODE ZERO disabling the correlators SEPARATELY CODE LOCKED BETWEEN TRANSITIONS BITS of code in the local PRN code. THE RESULT IS THE SAME, THAT IS, A SYSTEM PRODUCES CORRELATION MEASUREMENTS NEAR ZERO IN ADDITION TRANSITIONS BITS of code in the local PRN code.
