Dear FULLY RETARDED Paul. I've extracted this part from your last post,
as A SAMPLE OF YOUR COMPLETE IGNORANCE, IDIOCY AND INDOCTRINATION.
I told you that the GPS 10.23 Mhz is REGENERATED from the L1 received
carrier IN ANY GPS RECEIVER, which has a CHEAPER TCXO oscillator. This
recovery, made through PLL and filtering, is ESSENTIAL for the receiver
TO TIME THE ARRIVAL OF MARKS EMBEDDED IN THE L1 CARRIER.
As you are A COMPLETE ASSHOLE, 100% IMBECILE AND LIVE WITH AN
INCREASINGLY FOSSILIZED BRAIN, I let that ChatGPT speak for me.
Quoting Paul:
**********************************************************************
The rate adjustment is made to make the SV clock be in sync to UTC.
Since all frequencies in the SV are derived from the same frequency
standard which is adjusted down by ((1-4.4669e-1), this has
the secondary effect that the L1 carrier is emitted as
1575.4199992966223 MHz, and will be 1575.42 MHz measured by UTC.
When the carrier reaches the receiver it is Doppler shifted
up to Δf/f = ± 1e-7 , up to 200 times the GR correction.
The frequency of the carrier is irrelevant, the receiver
must have bandwidth enough to receive the carriers from
up to 12 satellites. The carriers are all Doppler shifted
differently.
The satellites are not separated by their frequency, but
by their PRN sequence.
I won't bother to comment your confused babble below.
I will laugh at it though!

Learn something, fucking asshole:
Question to ChatGPT: Can you tell me how any GPS receiver recovers the
10.23 Mhz TCXO frequency of the GPS satellite from the reception of the
L1 carrier?
Answer from ChatGPT:
--------------------------------------------------------
Sure! To explain how a GPS receiver recovers the 10.23 MHz TCXO
frequency from the reception of the L1 carrier, let's break it down into
a few steps:
1. The L1 Carrier and GPS Signal Structure
- The GPS L1 carrier is transmitted at a frequency of 1575.42 MHz, which
is a radio frequency.
- This carrier is modulated by two primary signals:
- C/A code (Coarse/Acquisition code), a pseudo-random noise (PRN) code
used for civilian GPS.
- Navigation message that includes time and ephemeris data.
2. The 10.23 MHz TCXO in GPS Receivers
- The 10.23 MHz signal is typically the frequency generated by the
Temperature Compensated Crystal Oscillator (TCXO) inside the GPS
receiver.
- This frequency is crucial because it provides a stable timing
reference for the receiver's operations, especially for demodulating and
synchronizing with the GPS signals.
- The 10.23 MHz is closely tied to the GPS signal because it is the
frequency used in the C/A code modulation scheme.
3. How the Receiver Synchronizes with the L1 Carrier
- The GPS receiver uses the L1 carrier to perform a process called
"carrier tracking". The key part of this process is recovering the exact
phase of the L1 signal in order to demodulate the C/A code.
- The C/A code has a 1.023 MHz rate (this is the frequency of the chip
rate, not the L1 carrier), which is derived from dividing the 10.23 MHz
reference clock of the GPS receiver by 10. This rate is what the
receiver uses to decode the C/A code.
4. Phase-Locked Loop (PLL) or Frequency Locking
- The GPS receiver uses a Phase-Locked Loop (PLL) or other
synchronization techniques to lock onto the L1 carrier frequency.
- The receiver’s TCXO at 10.23 MHz plays a critical role in maintaining
synchronization. When the L1 carrier is received, the receiver needs to
extract the modulated signal, which is often done by mixing the L1
carrier with a local oscillator in the receiver that is a multiple or a
fraction of the 10.23 MHz TCXO.
- By adjusting the local oscillator to match the frequency and phase of
the incoming L1 signal, the receiver effectively recovers the 1.023 MHz
rate of the C/A code from the L1 carrier, which corresponds to the 10.23
MHz clock that the receiver is using.
5. Recovering the 10.23 MHz from L1
- The GPS receiver’s local oscillator (which is based on the 10.23 MHz
TCXO) is usually a multiple of this frequency, so the receiver can
generate the correct frequency to mix with the L1 signal.
- The frequency of the 1.023 MHz C/A code is recovered by the receiver,
and once the C/A code is decoded, it effectively locks onto the 10.23
MHz TCXO frequency used to modulate the GPS signal.
In summary, a GPS receiver recovers the 10.23 MHz TCXO frequency from
the L1 carrier through a process of carrier tracking, using a PLL to
synchronize the receiver’s internal clock with the phase and frequency
of the incoming L1 signal. This allows the receiver to demodulate the
C/A code and, indirectly, maintain the stable 10.23 MHz reference clock
for time and position calculations.
