GOES‐16/ABI Thermal Emissive Band Assessments Using GEO‐LEO‐GEO Double Difference [PDF]
Earth and Space Science, 2019 Geostationary satellite (GOES)‐16/Advanced Baseline Imager (ABI) and Himawari‐8/Advanced Himawari Imager (AHI) represent a significant improvement over the imagers on board previous GOES.

Noises in Double-Differenced GNSS Observations
Energies, 2022 Precise data processing from the Global Navigation Satellite Systems (GNSS) reference station network is mainly based on a combination of double-differenced carrier phase and code observations.

VESUVIO—the double difference inverse geometry spectrometer at ISIS [PDF]
Physica B: Condensed Matter, 2004 The VESUVIO spectrometer at the ISIS pulsed neutron source performs inelastic neutron scattering at high-energy and wave vector transfers, employing gold and uranium resonant foils. A factor of two improvement in the instrumental resolution has been achieved by making use of the double filter difference method.

Double-difference adjoint seismic tomography [PDF]
Geophysical Journal International, 2016 We introduce a `double-difference' method for the inversion for seismic wavespeed structure based on adjoint tomography. Differences between seismic observations and model predictions at individual stations may arise from factors other than structural heterogeneity, such as errors in the assumed source-time function, inaccurate timings, and systematic ...

Seeing Double: Machine Vision, Difference, and Repetition
communication +1, 2023 In thinking about human and machine vision in relation to doppelgangers, I turn to Francois Brunelle’s photographic project “I’m not a look-alike.” Here the artist captured people that were not related yet looked very similar.

Dizhen xuebao, 2021 分别运用双差定位法、结合波形互相关的双差定位法和结合波形互相关的双差层析成像法，对唐山地区2010年1月至2020年7月河北地震台网记录的4 874个地震事件进行重定位。结果表明：结合波形互相关的双差层析成像法的定位精度高于其它两种方法，地震走时均方根残差由初始的0.71降至0.27；重定位后的震中分布更加集中，线性分布更明显，优势分布方向为NE向，与该区域断层走向基本一致；重定位后震源深度主要集中在5—15 km，分布形态更接近于正态分布，结果更加合理。从重定位后的震中空间分布可见在唐山 ...

INS-Aided Multi-Antenna GNSS Carrier Phase Double Difference Spoofing Detection
IEEE Access, 2023 The effective spoofing detection can prevent GNSS receiver from providing erroneous positioning, velocity and timing information. Most of the available multi-antennas carrier phase double difference-based spoofing detection methods, regardless of the ...

The double difference property for some classes of functions [PDF]
Real Analysis Exchange, 1999 The paper relates the difference property of \(F\) to the double-difference property of a pair \((F, F^{(2)})\), where \(F\) and \(F^{(2)}\) are classes of real-valued (and possibly periodical) functions of one and two real variables, respectively, sharing the same ``characterisation'' property.

Performance Enhancement of Land Vehicle Positioning Using Multiple GPS Receivers in an Urban Area
Sensors, 2016 The Global Positioning System (GPS) is the most widely used navigation system in land vehicle applications. In urban areas, the GPS suffers from insufficient signal strength, multipath propagation and non-line-of-sight (NLOS) errors, so it thus becomes ...

L’architettura come sistema di differenze
Aisthesis, 2012 There are many cases in which the “direction” of architecture seems to be indifferent to the architect who designs it. Among these, the Guggenheim Museum in New York by Frank Lloyd Wright is highly emblematic: through the long and troubled project’s ...
