Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Claim Rejections - 35 USC § 102
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
Claim(s) 1 and 16 are rejected under 35 U.S.C. 102(a1) as being anticipated by Phan (US-20210364649-A1).
Regarding claims 1 and 16, Phan discloses a method and a GNSS receiver (see Fig. 3) comprising:
an antenna (308 in Fig. 3) to receive GNSS signals from a set of GNSS SV s;
an RF front end coupled to the antenna to amplify the GNSS signals (receiver electronics 310 can amplify and /or filter RF signals, paragraph 0044-0045);
an analog to digital converter (ADC) coupled to the RF front end to generate a digital
representation of received GNSS signals (a receiver front end implies an amplifier to amplify signals and an ADC);
a baseband memory coupled to the ADC to store the digital representation (memory 320 in Fig. 3, paragraph 0043);
a GNSS processing system coupled to the baseband memory to process the received
GNSS signals (GNSS receiver 205 can execute signal tracking channels which correlate the
received radio frequency signals to predetermined code signals in order to calculate pseudorange values (e.g., code position measurements, carrier phase measurements, and/or the like), paragraph 0033), the GNSS processing system including a set of correlators that provide correlation outputs, wherein the GNSS processing system includes processing logic to acquire, from primary pseudorandom number (PRN) codes in the received GNSS signals, primary code phases for five (5) GNSS SVs (see Fig. 3, satellites 110A to 110N), in the set of GNSS SVs, to derive pseudoranges to each of the five GNSS SVs;
wherein the GNSS processing system includes processing logic to acquire, from at least
one secondary PRN code in the received GNSS signals, a secondary code phase of at least one
GNSS SV, the acquired secondary code phase providing an estimated time data relative to an
epoch boundary of the at least one secondary PRN code (the receiver 305 identifies the secondary code phase of the received signal and aligns the secondary code phase to coherently integrate over a longer integration interval (or period). paragraph 0045);
wherein the GNSS processing system includes processing logic to compute an estimated
GNSS time using the derived pseudoranges to each of the five GNSS SV s and the estimated time data derived from the acquired secondary code phase (the secondary code phase is determined from the unique known pattern of chip transitions of the secondary code sequence and the potential effects of navigation data symbol transitions on the pattern of secondary code chip transitions, paragraph 0045)(chip transition indicates epoch boundary).
Allowable Subject Matter
Claims 2-15, 17-26 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
