Do you really, seriously believe that 'relativists' claim that
the receiver can measure the frequency of the L1 carrier to be
1575.42 MHz = 154*10.23 MHz and can use this to recover the
master TCXO frequency of 10.23000000 Mhz? :-D

You claim to be an engineer and must understand that it is
no way a GPS receiver can measure the L1 frequency with any precision
better than ~ 1575420000 ±150 Hz.

DEEPSEEK ANSWER:
----------------------------------------------------------
5. Conclusion
The commenter is correct that directly measuring the L1 frequency with a
precision of ±0.025 Hz is unrealistic for a GPS receiver.

Imbecile, I was working with spread spectrum transmission when you were
learning how did a germanium transistor worked (circa 1980). It evolved,
using digital encoding of data, 20 years later into what was known as 2G
CDMA transmissions for mobile telephony, competing with the European 2G
GSM (based on frequency multiplexing), which won the commercial race in
just 4 years, by 2004.
Every one of the 33+ GPS SV uses THE SAME L1 frequency, which means that
any GPS receiver has to separate the signals of each SV by tracking the
distinctive PRN code of each satellite for coarse demodulation. To do
so, the L1 frequency at the GPS receiver HAS TO BE DETECTED AND
MULTIPLIED BY A LOCAL SIGNAL OF ABOUT 120 x 10.23 Mhz, which is
generated within the receiver from the LOCAL TCXO oscillator of 10.23
Mhz. This heterodyne technique allows each GPS SV L1 signal to be
transported (by analog multiplication) to a suitable IF filter of about
400 Mhz, where each signal is digitized and sent to the DSP to extract
the stream of chirps at 1.023 Mhz, and to start the correlation process
that allows the GPS receiver TO EXTRACT EACH INDIVIDUAL SIGNATURE of the
received GPS SV.
The FOUR RECOVERED SIGNALS WITH THE HIGHER SNR are selected to process
and identify the signature of the four GPS SV, which are locally stored
in the GPS receiver memory.
Then, a sophisticated process of tracking of each of the four baseband
signals start, in order TO CALCULATE the almost exact time of arrival of
each mark.
The next phase, involving RECURSIVE ALGORITHMS for refinement of FOUR
DATA SETS start, which involves matrix operation and feedback. After
three or four steps in the math of trilateration, the EXACT POSITION of
the GPS receiver is obtained (within the error margins for such
operation with only one carrier: L1).
If more precision is required, other carrier frequencies (L2, etc.) are
used, allowing accuracy of cm in the position of the receiver. If more
than 4 SV are used, the mathematics of trilateration become more
complex, but accuracy increases (as well as the COST of the GPS
receiver).
The above explanation is to show your INFANTILE ATTITUDE by conveniently
using ONLY PARTS of my posts. It must be that you're living your second
childhood, as your are approaching senility.
The above PLUS that you're a fucking relativist, which uses the usual
techniques of your people to DECEIVE, DISTORT, LIE, MOCK, CHANGE WHAT
WAS SAID/WRITTEN, ETC., because you all are a disgusting bunch of
FRAUDSTERS, that can't behave in any other way. You're BAD PEOPLE. You
always were.
