|Abstract:||This technical report provides the results from the [extremely high] performance evaluation of the direct acquisition of the GPS-like VBOC signals against noise, channel impairments, and interference using real GPS or GNSS signals. We initially compare and contrast the performance of VBOC1(1,1,0.5) and VBOC2(1,1,0.4) against noise and channel impairments, no data and only four GPS-like satellite signals in the lab. We, then, graduate include one effect at a time as the test setup gradually manifests a more realistic scenario from where it is shown that a high-performance acquisition engine for direct acquisition of GPS-like VBOC signals can achieve time to first fix (TTFF) of 100 seconds with initial time uncertainty (ITU) of 100 ns and jamming/signal ratio (JSR) of 90 dB against additive white Gaussian noise (AWGN) or other “unknown” jammers with bandwidth of ?/+ 1 or 4 MHz. Giftet Inc. Indoor Geolocation Systems MATLAB library offers unique and unlimited capabilities for analysis, simulation, and design tool for the Radio Frequency (RF), Intermediate Frequency (IF), and Baseband (BB) sections analysis and simulation of future Keysight, Locata, NovAtel, etc. products. Index Terms—VBOC1, VBOC2, BOC, GPS, GNSS, interference, noise, high-performance, acquisition, TTFF, ITU, JSR.|
